NASA Langley is developing Traffic Aware Strategic Aircrew Requests (TASAR). TASAR features a cockpit automation system that monitors for potential flight trajectory improvements and displays them to the pilot. These wind-optimized flight trajectory changes are pre-cleared of potential conflicts with other known airplane traffic, weather hazards,
We are able to view the train schedule after selecting the station, view the routes between the stations by selecting the start and end destination, view the map, and know about the various geographical features of the place the train is crossing through like the rivers,
No-Access Armor transparent polymer is a revolution in construction and provides increased safety while reducing weight/maintenance. Traditional safety glass is heavy, difficult to cut, fragments when impacted, yellows/delaminates over time, and is limited in applications.
No-Access Armor (NAA) is ballistic/tornado/hurricane-resistant, load-bearing,
NASA's Langley Research Center has developed an inexpensive, long endurance vertical takeoff and landing UAV. It is capable of flying for 24 hours, landing in a 50 x 50 zone, and can be loaded into the back of a cargo van for easy transport. In addition,
