The Ryan YQM-98 R-Tern (also called Compass Cope R) was a developmental aerial reconnaissance drone developed by Ryan Aeronautical. It could take off and land from a runway like a manned aircraft, and operate at high altitudes for up to 24 hours to perform surveillance, communications relay, or atmospheric sampling.

yqm-98a As the production Compass Cope vehicle, Teledyne Ryan proposed their Model 275. This featured a competely new engine installation with a General Electric TF34 turbofan, and had a redesigned tail unit.

The Boeing YQM-94 B-Gull (also called Compass Cope B) is a developmental aerial reconnaissance drone developed by Boeing. It could take off and land from a runway like a manned aircraft, and operate at high altitudes for up to 24 hours to perform aerial surveillance, communications relay, or atmospheric sampling.

2018年1月14日 · The YQM-98A R-Tern (Model 235) Compass Cope-R was a Teledyne-Ryan high-altitude, long-range research vehicle designed for long endurance reconnaissance. It took off and landed on conventional...

The Ryan YQM-98A was variously known as the "COMPASS COPE R", "COPE R", or "R-Tern". Its general configuration was similar to that of the Boeing COMPASS COPE B, resembling a jet sailplane with a twin-fin tail, retractable tricycle landing gear, and an engine in a pod on its back.

2006年12月22日 · The YQM-98A was designed in 1973 for an Air Force competition to select a drone for high altitude signals intelligence. Both the YQM-98A and the Boeing designed YQM-94A began testing in 1974. During the tests the Teledyne drone set what was then a record for unmanned, unrefueled flight duration with a time of 28 hours 11 minutes and 12 seconds.

The program consisted of the Boeing YQM-94A and the Teledyne Ryan YQM-98A. Both vehicles used conventional landing gear to permit runway takeoff and landing. The Compass Cope was a large,...
