NASA plans to build supersonic civil planes

NASA's supersonic airplanes have lower noise levels than the Concorde, which can be tested by 2019.

NASA is adopting designs of ultra- low noise civil aircraft with a noise level of less than 60 dBA compared to modern supersonic aircraft such as Concorde from technology contractors. Aviation Week.

By the end of July, Lockheed Martin will offer a preliminary design of a $ 20 million, $ 20 million, low noise supersonic concept with NASA. NASA will evaluate preliminary designs submitted by NASA and other contractors for four days.

NASA will then sign a contract to build the Super X aircraft with the contractor offering the best solution.

NASA will then sign a contract to build the Super X aircraft with the contractor offering the best solution. The winning design will undergo rigorous testing in 2019.

"We are ready to continue to build this test plane," said Rob Weiss, executive vice president and general manager of advanced development at Lockheed Martin.

X-ray test flights will go through two phases at the Armstrong Flying Research Center in California and be completed at Edwards Air Force Base, California.

U.S. land-based landings were banned in March 1973. Concorde is the only supersonic airliner ever served in the United States, but this model has now ceased to operate.
