Smaller turbines put out about 12 lbf (53 N) of thrust, while larger microturbines can put out as much as 45 lbf (200 N) of thrust. Radio-control jets require an onboard FADEC (full authority digital engine control) controller; this controls the turbine, as on a full-size aircraft. RC jets also require electrical power.
N833NA, the Boeing 720 aircraft involved in the test. NASA and the Federal Aviation Administration (FAA) conducted a joint program for the acquisition, demonstration, and validation of technology for the improvement of transport aircraft occupant crash survivability using a large, four-engine, remotely piloted transport airplane in a controlled impact demonstration (CID).
Slocum was the last one to leave the jet, three minutes before impact. Shanle then flew the jetliner by remote control, from the chase plane. [9] Aftermath at the crash site. Note that the cockpit broke off. The jetliner hit the ground at 140 miles per hour (120 kn; 230 km/h), with a descent rate of 1,500 feet per minute (460 m/min). [10]
There was also a TF-104G Starfighter chase plane with a set of backup controls which could take control of the HiMAT in the event that the remote pilot on the ground lost control. [ 2 ] Advances in digital flight control gained during the project contributed to the Grumman X-29 experimental aircraft, and composite construction are used widely ...
In December 2014, NASA awarded Lockheed Martin a contract to study the feasibility of building the SR-72's propulsion system using existing turbine engine technologies, The $892,292 (~$1.13 million in 2023) contract funded a design study to determine the viability of a TBCC propulsion system by combining one of several current turbine engines, with a very low Mach ignition Dual Mode Ramjet (DMRJ).
P&W was to control 60% of the program, shared with IAE partners MTU and FiatAvio but not Rolls-Royce, and possibly with Volvo and MHI. [5] Its LP turbine ran at 9,160 rpm, reduced by 3:1 for a 3,250 rpm fan having a 1,050 ft/s (320 m/s) blade tip speed down from 1,400 ft/s (430 m/s), dropping noise to 30 EPNdB cumulated below Stage 3 requirements.
