Windstar YF-80
The Windstar YF-80 is an American single-seat homebuilt replica of the Lockheed F-80. By 1987, the project was not complete, resulting in a court case between investors. The prototype was re-engined with a Turbomeca Marboré II turbine engine, as the Stargate YT-33.
Design and development
The YF-80 is a two-thirds scale replica of a Lockheed F-80 or T-33. The aircraft is a composite-construction, single-engine, low-wing design, with retractable tricycle landing gear. The tip tanks are removable for aerobatic flight. The aircraft is powered by a Chevy 350 V-8 turbocharged engine driving a turbine thrust section. The thrust section is driven by belts with high gear ratios to drive the turbine closer to the rotational speed it was originally designed for.The aircraft project was intended to showcase the Davis engine technology, with a static prototype displayed in 1977. Burt Rutan was approached to build the composite fuselage, but the US$240,000 cost estimate was declined. Davis attempted to produce a production prototype fuselage for US$80,000.
Stargate YT-33
The Stargate YT-33 is an American turbine powered prototype homebuilt aircraft that was designed and intended to be produced by Stargate, Inc., of McMinnville, Oregon. It was introduced in 1994. The aircraft is a 2/3 scale replica of the Lockheed T-33 jet trainer. Listed as "under development" in 1998, the YT-33 was planned to be supplied as a kit for amateur construction, but it is unlikely any kits were ever shipped.Design and development
The YT-33 features a cantilever low wing, a two-seats-in-tandem enclosed cockpit under a bubble canopy, retractable tricycle landing gear, and a single jet engine.The aircraft is made from composite material. Its span wing has a wing area of. The prototype uses a thrust Turbomeca Marboré IIC jet powerplant.
The aircraft has a typical empty weight of and a gross weight of, giving a useful load of. The aircraft has a fuel capacity of or of Jet-A.
The ISA standard temperature, sea-level, no-wind, take-off distance is, and the landing roll is.
The manufacturer estimated the construction time from the proposed kit to be 3000 hours.
