Visualizing quieter supersonic flight by Staff Writers Moffett Field CA (SPX) Jun 30, 2021
NASA's X-59 Quiet SuperSonic Technology X-plane is designed to fly faster than the speed of sound without producing sonic booms - those loud, startling noises which can be disruptive to humans and animals. Currently, commercial aircraft aren't allowed to fly faster than the speed of sound over land because of the objectionable sonic booms they cause for those on the ground. This experimental plane will fly at a cruise speed roughly double that of a commercial jet while keeping aircraft noise down to a quiet "sonic thump" - or even no sound at all - as heard on the ground when the plane flies overhead at supersonic speeds. To be sure the X-59's design will perform within expected noise limits, NASA is working closely with its contractor, Lockheed Martin, to create a database of computational fluid dynamics simulations to verify the aircraft's supersonic performance. The database will include simulations for all possible combinations of the settings that a pilot uses to control the aircraft and the flight conditions that may be encountered during flight.
Sikorsky to build nine more CH-53K King Stallion helicopters for U.S. Marines Washington DC (UPI) Jun 28, 2021 Lockheed Martin's Sikorsky division will build nine more CH-53K heavy-lift helicopters for the U.S. Marine Corps, the Navy Air Systems Command said. The $878.7 million contract, announced in a statement on Friday, includes an option to build and deliver nine more of the aircraft at a lower price. The helicopters are part of a plan to build 33 of the helicopters, known as "King Stallions," for the Marine Corps. Three have already been delivered, and Sikorsky will begin deliveries o ... read more
