American powered parachute

Twin General information Type Powered parachute National origin United States Manufacturer Gemini Powered Parachutes Status Production completed (2007) Number built 60 (2005) History Manufactured 2002-2007

The **Gemini Twin** is an American [powered parachute](/source/Powered_parachute) that was designed and produced by [Gemini Powered Parachutes](/source/Gemini_Powered_Parachutes) of [Culver, Indiana](/source/Culver%2C_Indiana). Now out of production, when it was available the aircraft was supplied as a complete ready-to-fly-aircraft.[1][2]

The aircraft was introduced in about 2002 and production ended when the company went out of business in 2007.[3]

## Design and development

The Twin was designed by a former [Buckeye Industries](/source/Buckeye_Industries) employee to comply with the [Fédération Aéronautique Internationale](/source/F%C3%A9d%C3%A9ration_A%C3%A9ronautique_Internationale) [microlight](/source/Microlight) category and the US [FAR 103 Ultralight Vehicles](/source/FAR_103_Ultralight_Vehicles) rules as an ultralight trainer. It features a 45 m2 (480 sq ft) [parachute](/source/Parachute)-style wing, two-seats-in-[tandem](/source/Tandem) accommodation, [tricycle landing gear](/source/Tricycle_landing_gear) and a single 64 hp (48 kW) [Rotax 582](/source/Rotax_582) engine in [pusher configuration](/source/Pusher_configuration).[1]

The aircraft carriage is built from a combination of bolted [aluminium](/source/Aluminium) and [4130 steel](/source/4130_steel) tubing. In flight steering is accomplished via foot pedals that actuate the canopy brakes, creating roll and yaw. On the ground the aircraft has lever-controlled nosewheel steering. The main landing gear incorporates spring suspension. The acceptable power range is 50 to 100 hp (37 to 75 kW)[1][2]

The aircraft has an empty weight of 157 kg (346 lb) and a gross weight of 385 kg (849 lb), giving a useful load of 228 kg (503 lb). With full fuel of 40 litres (8.8 imp gal; 11 US gal) the payload for crew and baggage is 200 kg (441 lb).[1]

The standard day, sea level, no wind, take off with a 64 hp (48 kW) engine is 350 ft (107 m) and the landing roll is 100 ft (30 m).[2]

## Operational history

In 2005 the company reported 60 examples had been completed and flown.[2] In July 2015, 15 examples were [registered](/source/Aircraft_registration) in the United States with the [Federal Aviation Administration](/source/Federal_Aviation_Administration).[4]

In 2004 Jean Pierre la Camus reviewed the design in the *World Directory of Leisure Aviation* and described the Twin as "soundly engineered".[1]
