RM-30 San Real

The RM-30 San Real is a supersonic high altitude heavy strategic bomber capable of delivering nearly 35 metric tonnes of ordnance to targets over 8000 kilometres away. The RM-30's production is highly classified and the date that the San Real entered production is estimated to be in mid 2010. The program was born out of the need to replace the aging Rockwell B1-B Lancer fleet which had served Mikoyan-Guryevich superbly, and in some ways became the symbol of the nation. The RM-30 was designed to offer enhanced speed at high altitudes, an accomplished stealth capability and a bomb load sufficient to neutralize a number of targets on a single bombing run. The RM-30 is produced solely by Gemballa Avionics Development and has been released to sale to the rest of the world. Make no mistake that the RM-30 San Real is possibly one of the most lethal aircraft ever produced, capable of wiping out not one, but multiple cities on a single bombing run.

Origins

In 2006, a competition for a new bomber was announced by the Mikoyan-Guryevich Air Force. The builder for this replacement aircraft was selected as Gemballa Avionics Development, the company responsible for the development of the superb GM-24 multirole fighter. The first prototype of the RM-30 flew in late 2009, where it was immediately accepted by the review panel of the competition. Minor modifications were made and the RM-30 entered production in mid 2010. So far, 50 have entered service with Mikoyan-Guryevich and only one has been used in combat. RM-30 'MGR0010' was deployed to neutralize a seperatist anti-government terrorist camp operating in far north west Mikoyan-Guryevich.

Avionics

The RM-30's avionics include an uprated version of the Cervelo SS-16 radar warning receiver/emissions locator system, Cervelo SB-77 Infra-Red and Ultra-Violet MAWS (Missile Approach Warning System) and a more powerful version of the Cervelo DD-18X Active Scan radar. The DD-18X features both long-range target acquisition and low risk of interception of its own signals by enemy aircraft due to its complex set up and frequent channel changing.



The SS-16 is a passive receiver system capable of detecting the radar signals in the environment. It is composed of 50 antennas smoothly blended into the wings and fuselage that provide all around coverage plus azimuth and elevation information about enemy aircraft. With significantly greater range than the radar, it enables the RM-30 to limit its own radar emission to preserve its stealth, as it does in the GM-24 fighter. As a target approaches, the receiver can set the DD-20X radar to track the target with a very narrow radar wave, which can be as focused as precisely to 1° by 1° in azimuth and elevation. As the RM-30 is not designed for air-to-air combat, its on board electronics asses the threat.

The Cervelo DD-20X Active Scan radar is designed for large strike operations and features a low-observable, active-aperture, electronically-scanned array that can track multiple aircraft, in any weather, including storms. The RM-30 also features the Cervelo S5 Terrain following radar. The system works by transmitting a radar signal towards the ground area in front of the aircraft. The radar returns can then be analysed to see how the terrain ahead varies, which can then be used by the aircraft's autopilot to maintain a reasonably constant height above the earth. This technology enables flight at very low altitudes, and high speeds, avoiding detection by enemy radars and interception by anti-aircraft systems. This allows the pilot to focus on other aspects of the flight besides the extremely intensive task of low flying itself.
The Cervelo DD-20X Active Scan changes electromagnetic frequencies at more than 1,000 times per second to greatly reduce the chance of being intercepted by an enemy aircraft. If the RM-30 is spotted, it can then focus its radar emissions on an enemy aircraft, to overload enemy sensors and thus jamming the enemy radar. If it is engaged, it can use a variety of counter measures including chaff, flares to defeat enemy missiles.

The radar's information is processed by four Indeon Common Integrated Processors (CIP), which is effectively double the system of the GM-24 fighter. Each CIP can process 12 billion instructions per second and has one gigabyte of memory, allowing it to store a wealth of information and making the system nearly impossible to overload. Information can be gathered from the radar and other onboard and offboard systems, where it is then filtered by the CIP which will effectively 'gist' the meanings of the signals onto several cockpit displays, enabling the crew to remain on top of complicated situations by having all the information simply presented. The more powerful radar has an estimated range of 500 miles, also giving the RM-30 an AWACS capability. The RM-30 is capable of communicating with GM-24 fighters, in which the RM-30 transmits its radar signals to the fighters, allowing them all to see off the RM-30's radar screen.

In addition to this powerful array, the RM-30 also has a limited Battlespace Command network capacity, in the sense that the radar system on board the RM-30 can transmit and receive data to and from other fighters. This allows targets which the RM-30 can detect to be seen among all fighters within communication with the bomber, and conversely and fighter running a forward screen for the bomber can relay any information of enemy fighters to the RM-30, which then can be shared amongst all fighters. The capacity of this is somewhat limited, the RM-30 can only communicate with 12 fighters at a time due to the complexity of the system. However, several RM-30's can keep contact with 12 fighters each while communicating data to other RM-30's as well, therefore, using the RM-30 as a data link device, a single fighter can project its radar information to any aircraft within contact of an RM-30, provided the RM-30's are in contact with one another.

The sheer power and capability of the DD-20X means that it can scan and track almost any aerial or ground target no matter the size of the enemy's radar cross section. From a distance of 500km, the DD-20X can successfully detect a target which has a radar cross section of roughly five square metres and can detect a target with a cross section of less than 10 square centimetres from fifty kilometres away.

In total, the RM-30 can simultaneously track and record movements for a total of 108 different aerial or ground targets and engage up to sixteen at once using active radar homing missiles. This gives the RM-30 the ability to address any numbers deficit it may go into battle facing by effectively fighting multiple targets at any one time.


Cockpit



The cockpit was designed from the outset to be a fully glass cockpit wihtout any tradtional analouge instruments. This presents the challenge of the chance of engine failure in which all the cockpit instruments fail as well. Two small inlets in the fuselage are automatically opened during engine failure, which suck in air to spin two generators, which provide enough power to keep the cockpit operational.

The main features of the RM-30 cockpit include a simple and rapid start-up procedure, a highly developed Human-Machine Interface, a lightweight crew helmet designed from automotive racing helmets incorporating carbonfibre and kevlar, large anthropometric accommodation and highly integrated threat warning system and offensive weapons system as previously discussed. The cockpit of the RM-30 is large enough for a crew of four, with ample room provided for the two pilots, the defensive suite operator and the offensive systems operator. A small compartment directly behind the cockpit houses a lavatory and basin, which may become necessary on long flights.

The RM-30 also features a special night vision system not unlike the system on the GM-24 Fighter. A strip of Infra Red sensors are mounted directly below the windshield of the RM-30, and when these are engaged, they project the image directly on to the windshield itself, giving the pilots the impression the world has illuminated as such.

Offensive Systems

The RM-30 was always designed to have a huge payload of conventional, guided and gliding bombs, the need for this has been proven time and time again through conflicts involving heavy bombers. However, the concept of a stand-off missile platform was also toyed around with and designers decided to change the way the RM-30 worked by turning this stable platform into an airborne arsenal, capable of carrying some of the worlds deadliest missiles at speeds of up to Mach 2.8.

The RM-30 has three internal bomb-bays mounted in the underside of the fuselage. Each of these bomb-bays can carry nine tonnes of ordnance in each of the two smaller bays mounted behind the large central bomb bay which can carry 18 tonnes of ordnance. Ordnance can be comprised of missiles, bombs and mines which can be carried in a variety of configurations. Launching ordnance requires opening the weapons bay doors for less than a second. The ordnance is pushed clear of the airframe by hydraulic arms where they then fire at the target. Carrying missiles and bombs internally enhances its stealth capability and returns lower drag due to the absense of underwing armament permitting higher speeds, both maximum and cruise, and a much longer range due to less fuel being required.

Also mounted before the bomb bays are two rotary rocket launchers capable of holding cruise missiles. The missiles are tasked to their target by the offensive systems operator and are then fired. Each launcher can carry 6 short to medium range cruise missiles or in a revolver style system.

Defensive Systems

Mounted to the front and rear are 'missile chutes' which hold AIM-9 short range missile, but can be configured to fire any short range missile. Each chute holds four missiles which are used as self defence. The radar automatically locks on to a target, defensive suite operator fires a missile out of the front or rear chute, and the missile is guided towards the threat aircraft. This is used for last ditch purposes, the RM-30 should avoid air-to-air combat where possible.

The RM-30 also carries a chaff and flare system to defeat missiles once they are in the air.

The RM-30's greatest asset is its speed; the RM-30 can evade combat by simply running away. With it's cruise speed of Mach 2.6, the RM-30 can sustain high supersonic speeds for hours while many would be interceptors would only manage these speeds for short periods of time. This high speed also allows the RM-30 an element of suprise during attacks as the RM-30 can approach and attack targets much faster than many other bombing aircraft.

Should this speed be insufficient, the RM-30 can attain and hold Mach 2.8 for a time of 140 seconds in bursts. This should only be used in emergencies as attaining this speed does induce a serious stress on the airframe. At no stage should pilots exceed Mach 3.0.

Thrust & Thrust Vectoring

The RM-30 is one of a select few aircraft of its size to offer thrust vectoring, much less three dimensional thrust vectoring. The nozzles can be pointed 10 degrees in either direction on the y axis, and 10 degrees in either direction on the x axis, boosting agility to this enourmous aircraft and allowing the RM-30 to lose hydraulic pressure to it control surfaces and still be able to be landed. Variable altitude engine intakes are featured on both engines reducing the risk of compressor stall.

The RM-30 uses the incredible Azzuri R-R4000 to create enough thrust to be able to move at over Mach 2.8. The R-R4000 is a variable cycle engine which functions as both a turbojet and a fan-assisted ramjet, allowing the MR-SST to take off on a conventional turbojet engine and use ramjet efficiency at high altitude without having to worry about two different engines. At Mach 2.6, 75% of the engine's thrust comes from the ramjet , with the turbojet providing the remaining 25%. At lower speeds, the engine relies soley on the turbojet for thrust.



The R-R4000 is essentially a turbojet engine inside a fan-assisted ramjet engine. This was required because turbojets are inefficient at high speeds but ramjets cannot operate at low speeds. To resolve this, the airflow path through the engine varied, depending on whether ramjet or turbojet operation was more efficient, thus the term variable cycle. To create this effect, at speeds over 1500 mph the nose cone of the engine was pushed about 2 inches forward to improve the air flow in the ramjet cycle.

Air is initially compressed and heated by the shock wave cones, and then enters 4 stages of compressors, and then the airflow is split: some of the air enters the compressor fans (core-flow air), while the remaining flow bypasses the core to enter the afterburner. The air continuing through the compressor is further compressed before entering the combustor, where it is mixed with fuel and ignited. The flow temperature reaches its maximum in the combustor, just below the temperature where the turbine blades would soften. The air then cools as it passes through the turbine and rejoins the bypass air before entering the afterburner.

At around Mach 2.7, the initial shock-cone compression greatly heats the air, which means that the turbojet portion of the engine must reduce the fuel/air ratio in the combustion chamber so as not to melt the turbine blades immediately downstream. The turbojet components of the engine thus provide far less thrust, and the RM-30 flies with 75% of its thrust generated by the air that bypassed the majority of the turbomachinery undergoing combustion in the afterburner portion and generating thrust as it expands out through the nozzle and from the compression of the air acting on the rear surfaces of the spikes.

The turbojets of the RM-30 are constructed from a blend of materials which are used in tandem as well as in isolation from one another. A Turbine engine produces exhaust and internal temperatures far beyond that of a piston engine therefore new materials had to be developed in order to resist these temperatures. Composite materials were selected on the premise that they not only had the heat resistance to withstand temperatures at which steel would bend, but they are also much lighter than metals and would improve the power to weight ratio of the engine itself.

Components of the turbofan aft of the compressor fans, including the internal turbines of the turbofan as well as the turbine shaft, are constructed out of a composite ceramic material to resist against the extreme temperatures of the propulsion system. A ceramic is an inorganic, non-metallic solid prepared by the action of heat and subsequent cooling, this results in a crystalline substance. The ceramic material used within the turbine is silicon carbide, or a carbon ceramic material. Silicon Carbide is exceedingly hard, synthetically produced crystalline compound of silicon and carbon. The modern method of manufacturing silicon carbide for the abrasives, metallurgical, and refractories industries is basically the same as that developed by Acheson. A mixture of pure silica sand and carbon in the form of finely ground coke is built up around a carbon conductor within a brick electrical resistance-type furnace. Electric current is passed through the conductor, bringing about a chemical reaction in which the carbon in the coke and silicon in the sand combine to form SiC and carbon monoxide gas. A furnace run can last several days, during which temperatures vary from 2,200° to 2,700° C (4,000° to 4,900° F) in the core to about 1,400° C (2,500° F) at the outer edge. The energy consumption exceeds 100,000 kilowatt-hours per run. At the completion of the run, the product consists of a core of green to black SiC crystals loosely knitted together, surrounded by partially or entirely unconverted raw material. The lump aggregate is crushed, ground, and screened into various sizes appropriate to the end use.

Components of the turbine fore of the compression chamber and also components outside of the turbine itself are constructed from Aermet. Aermet is an ultra-high strength type of alloy steel where the main alloying elements are cobalt and nickel, but chromium, molybdenum, and carbon are also added. Aermet 100 was selected over Aermet 310 and Aermet 340 because of the greater fracture toughness that the 100 variant offers over Aermet 310 and Aermet 340, fracture resistance being paramount on the blades of the pair of compressor fans.

Airframe

The RM-30 incorporates Variable Geometry. Typically, a swept wing is more suitable for high speeds, while an unswept wing is suitable for lower speeds, allowing the aircraft to carry more fuel and/or payload, as well as improving field performance. A variable-sweep wing allows a pilot to select the correct wing configuration for the plane's intended speed. The variable-sweep wing is most useful for those aircraft that are expected to function at both low and high speed, and for this reason it has been used in the RM-30.

As a bomber, maneuvrability is no where near as important as a stable bombing platform therefore the RM-30 was made as a very stable design that could be easily controlled and flown. A conventional tailplane was added instead of a V-twin which would offer a lesser radar signature to reflect this idealogy and increase the stability of the RM-30 around the longitudinal (pitch) axis and the normal (yaw) axis.

The airframe exterior is made entirely from metal alloy, in this case Aluminium Lithium alloy. Al-Li alloy is a very light yet very strong material which poses great breakthroughs for the aviation community. While many regard composite materials as the future, composites still are not suited to flight at speeds which the RM-30 is designed to travel at, due to the enourmous skin friction experienced at these speeds. Thus, conventional alloys would have to be used yet engineers still needed to keep the empty weight of the San Real as low as possible, otherwise the extra weight would mean making sacrifices to some of the payload; something engineers were desperate to avoid as the heavy payload of the RM-30 was one of the primary reasons for it's conception.

Lithium is the least dense elemental metal, much less dense than alumiunium which is in itself less dense than most other metals, therefore when the two are alloyed together, the density and weight of the resulting material is less than that of the alloy while being stiffer at the same time and more resisitant to strain. Unlike composite materials, the alloy is capable of dealing with the high skin friction associated with high-supersonic flight. Al-Li alloy was also used on the wings which are acted upon by not only horizontal but also vertical forces unlike the fuselage and thus need to have the compressive and tensile strength required to outlast these forces, as well as resist the immense shearing forces which are also experienced at high speeds.

The exterior of the aircraft is optimized for flight at high-supersonic speeds and the aircraft is most efficient when it is travelling at its cruise speed of Mach 2.6.

The RM-30 was designed to be as 'slippery' as possible by effectively removing all drag inducing external features and mounting them inside the airframe, further enhancing its stealth and performance. The RM-30's stealth is reliant on radar absorbing paint and its low observance throughout the entire spectrum of sensors including radar signature, visual, infrared, acoustic, and radio frequency. This allows it to cover all angles, unlike the F-117 who focuses on the former and F-22 which conversely focuses on the latter. The materials used on the RM-30 are significantly more durable than those used on aircraft such as the B-2 and F-117, as the RM-30 can be kept out on the flightline instead of in climate controlled hangers, which the B-2 and F-117 require to remain effective.
