Portable Recovery System for an Unmanned Aircraft with a Straight Wing and a Tractor Propeller
(2019-07)
The recovery system development effort for an unmanned aircraft (UA) has been documented and examined. The development effort existed to satisfy a customer's need to recover an 80 lb aircraft on unimproved terrain. The ...
Turboprop performance and acoustic evaluation for a small unmanned aircraft variable-cycle engine
(2019-05)
Range and endurance of small unmanned aircraft systems (sUAS) driven by gas turbine engines are constrained by high thrust specific fuel consumption (TSFC) resulting from low overall efficiency. This study evaluates the ...
Unmanned Aerial System Inspection of Instrument Landing System Radio Signals
(2019-05-01)
This study investigates the use of a unmanned aerial system (UAS) for instrument landing system (ILS) signal inspection. A model of expected equivalent isotropic receiver power was built. A 10-meter radio tower was constructed ...
