The active members of Lockheed Martin Corporation always remain probing about the prospect aircraft design concept for supersonic overland flight. Use of simulation tools to illustrate the possibility of attaining over-land flight by radically lowering the sonic booms level via utilization of an “inverted-V” engine under wing configuration is the real theme of the Lockheed Martin Corporation team. Since the
Almost one decade has been passed when the final flight Concorde was landed at London’s Heathrow Airport. The concept of commercial supersonic air travel is still indefinable in the minds of people. But, it does not mean that NASA has stopped working on this major concept. The entire team of NASA is doing hard to build up solutions of dream in which they would be able to provide supersonic passenger travel off the ground yet again. It must be noted here that aerospace engineers have made noteworthy advancement in their perceptive of supersonic flight.
According to Peter Coen who is the manager of NASA’s High Speed Project “There are three fences especially to sonic boom, civil supersonic flight, high altitude emissions and airport noise. Among all three problems, the most significant on is the boom. The previous designs of supersonic aircraft reveal the lacking and necessitates of NASA’s low-boom project. These obligations indicate goals for efficiency of aerodynamic, boom noise and airport noise for an N+2 i.e., the second generation ahead of present technology. N+2 is the aircraft design that could be flying by the years 2020 through 2025.
Alike the past designs, the modern concepts are portrayed by a smooth fuselage, a needle-like nose and highly-swept or delta wings. This description reveals the detail of future designs for supersonic overload flight that have been trying to shape in the compact sonic boom. Various organizations are working with NASA in this aspect to finalize some highly suitable design. Up till now, the design of Lockheed Martin Corporation is considered as most appropriate design.
In this design, a very new concept has been illustrated by mounting two engines beneath the wing in a conventional pattern along with one extra centerline engine over the wing. The world-famous “Boeing Company” is the other industry collaborator now working with High Speed Project of NASA. The Boeing Company suggested some alterations in the proposed design by mounting two top engines in the exit just like the design of past aircraft design. Peter Coen again stated that installation of engine is a vital part of attaining a general low boom design.
