Developed by Rushing Aircraft and Kirov Design under the jointly owned company Advanced Supersonic Aerospace LLC, both the T-7 SST and the Corporate SST have a non-stop range of more than 4,000 nautical miles and are able to fly at uninterrupted supersonic speeds over land and sea. Up to 277 passengers in the T-7 and 12 passengers in the Corporate SST are able to travel in large cabin comfort to global destinations in half the time taken by current passenger aircraft. These jets have a patented design that revolutionizes travel with a low "shaped sonic signature" over 100 times quieter than the recently retired "Concorde" supersonic aircraft. In fact these jets give off no more than 65DB of noise during any phase of flight making them as quiet as a passing auto.
Explaining Shaped Sonic Signature
The advanced integrated design reduces the sonic signature to a sound level between the interior of a car at 70 miles per hour and normal talking levels. The sonic signature of our SST aircraft is not disturbing to people or structures on the ground below. A T-7 or Corporate SST cruising overhead is barely audible against ordinary background noise. This result is achieved by increasing the ratio of length to wingspan, using canards, a patented V-tail design and ensuring that the individual pressure waves generated by each part of the aircraft structure reinforce each other less significantly, producing a longer but less objectionable boom. Most jets are almost defined by the streaking sound made when the engine releases hot compressed gases. Not our stealthy military jets, which wouldn't be stealthy if you could hear them coming. So we used the same idea here which is to use a diffuser (basically a plate or airfoil) extending from below the nozzle of the engine. This directs the engine noise upward and away from the ground.
21st Century Supersonic Fuel Efficiency
Don't compare our aircraft to the inefficient designs of the past. These are radical designs that utilize bleeding edge supersonic technology to fly efficiently at twice the speed of sound with a barely noticeable sonic signature - less than 1/100th that of the Concorde. The T-7 uses four ALTEC-4 Variable Stream Control Engines (VSCE) while the Corporate SST utilizes two Tigner Infinity Variable Stream Control Engines (VSCE) to further enhance its superior design. Each engine design is a two stage design capable of efficient operation at takeoff, subsonic and supersonic speeds. These are hybrid engines that are like having both a turbo jet engine and ramjet.
The engine works by utilizing a Bypass fan design that allows for airflow to one of two combustion chambers. With the main turbine the engine provides the performance of a turbo jet. The turbo fan also helps compress the gases in the engine during supersonic flight. This will raise that critical compression ratio of the ramjet operation thus increasing fuel efficiency. The ramjet mode is activated when the bypass fan is activated, closing the bypass nozzle. Air is then ducted into the bypass burner and the engine operates as a ramjet.
Magnetic Brake System
When landing at high speeds, friction brakes wear out easily and create a lot of heat. Wear necessitates their replacement quite often. In order to solve this problem, our aircraft use magnetic brakes. This technology is primarily used on extremely high-speed land vehicles in order to slow them down. It also eliminates problems with hydraulic failures and leaks. Such problems can lead to dramatic ground loops, and overshoots attributable to failed brakes. The magnetic system prevents these problems and reduces weight. Magnetic brakes are ideal, as they produce no friction, and are low maintenance.
