Transport-2011: Making the aircraft of the future!
14 March 2012
TsAGI specialists have started a range of new work to further technological advances for a new generation of supersonic passenger and business aircraft. These airplanes will be able to cruise at supersonic speeds over populated areas. This research is being carried out in cooperation with a number of organizations: The Baranov Central Institute of Aviation Motor Development, OJSC Aviadvigatel, NPO Saturn OJSC, Sukhoi New Civil Technologies CJSC, Gromov Flight Research Institute, and SibNIA named after S.A. Chaplygin. This work is being done for the Industry and Trade Ministry as part of the Trasnport-2011 program.
The scientists will have to determine requirements regarding the primary challenges with this transport, that is, noise in the airport zone and the intensity of the sonic boom, and make preliminary recommendations for the shape of the future supersonic business planes to local developers.
The specialists plan to develop a functional structural diagram for the airframe, select the main construction materials and evaluate the preliminary design and weight dimensions of the planes, the main air intake systems, the engine exhaust and noise suppression systems.
An evaluation will also be carried out on the main characteristics of the range of engines in the supersonic business planes, including with future domestically produced engines.
An evaluation is to be made of the capabilities of existing methods of recording and registering sonic boom, requirements are to be developed for the composition and technical characteristics of measuring equipment needed for the flight certification testing of future supersonic business planes in terms of sonic boom.
Work is currently underway to produce an aerodynamic model of the body of the airplanes, models of the air intake and exhaust, including noise muffling devices, in order to carry out aerodynamic and acoustic testing.
Preliminary evaluations of noise levels during take-off and landing and the volume of the sonic boom of the aircraft at supersonic cruise speed have indicated the feasibility of keeping the noise at the level of future subsonic civilian airplanes and supersonic cruise flight over populated areas.
“This is the first work carried out in our country to create scientific and technological potential for supersonic business and passenger airplanes in the past two decades, with such broad participation between developers of aviation technology, applied science and flight research institutes,” TsAGI Deputy General Director and Director of the Aircraft Aerodynamics and Flight Dynamics Department Sergei Lyapunov said.
The development of high-speed aircraft is an urgent task facing the aviation industry. Resolving this issue may ensure a leading position within the aviation market in the future. Scientists from the US, the EU, China and Japan are all working on creating a new generation of supersonic passenger and business planes capable of cruising at supersonic speed over populated areas.
Based on calculations and design and experimentation work, recommendations will be made to domestic aircraft and engine producers regarding the shape of the future supersonic business and passenger planes. Moreover, the norms and requirements for these developments will be updated to include recommendations for new state sonic boom standards (GOST) for domestic airlines.
