The Scaled Composites Model 81 Catbird is a high-efficiency five-seat single-engine all-composite general aviation aircraft designed by Burt Rutan. It is unusual in that it incorporates both a small forward wing and a small conventional horizontal stabilizer on the tail.

Design and development

The Catbird was designed by Burt Rutan while his company, Scaled Composites, was owned by Beechcraft. The design was intended to replace the long-produced Bonanza. [1] The financial situation of Beech at the time, and competing projects, prevented consideration of commercial production. In 1988 Beechcraft sold Scaled Composites to the partnership of Rutan and the Wyman-Gordon Company, who also acquired the rights to a number of the designs, including Model 81 Catbird.

The aircraft was stored inverted from the ceiling of Scaled Composites' Mojave hangar until April 2011. The aircraft was restored to flying condition by Zach Reeder, Jim Reed and Mike Melvill. Catbird's second first flight was July 7, 2011.

World records

Catbird holds the world record for speed over a closed circuit of 5,000 km without payload of 334.44 km/h, set in 2014 [2] in Category C-1c, Landplanes with take-off weights from 1000 to 1750 kg.

The aircraft won the CAFE Foundation's 1988 California CAFE 400 race flown by Mike Melvill, in which aircraft compete for performance efficiency, as measured by fuel consumption, speed and payload. [3] Piloted by Dick Rutan, it subsequently won the 1993 CAFE Challenge with a record score and a speed of 210.73 mph (339.14 km/h), fuel consumption of 20.15 mpg (US miles and gallons) and a payload of 976.63 pounds (442.99 kg). [3] [4]

In 2014, the Catbird set another record, for speed over a closed 2,000 km course, from Mojave to EAA AirVenture Oshkosh, with an average speed of 339.50 km/h (211 mph).

Scaled Composites is an American aerospace company founded by Burt Rutan and currently owned by Northrop Grumman. It is located at the Mojave Air and Space Port in Mojave, California, United States. Founded to develop experimental aircraft, the company now focuses on designing and developing concept craft and prototype fabrication processes for aircraft and other vehicles. It is known for unconventional designs, for its use of non-metal, composite materials, and for winning the Ansari X Prize with its experimental spacecraft SpaceShipOne.

SpaceShipOne Suborbital air-launched spaceplane

SpaceShipOne is an experimental air-launched rocket-powered aircraft with sub-orbital spaceflight capability at speeds of up to 900 m/s (3,000 ft/s), using a hybrid rocket motor. The design features a unique "feathering" atmospheric reentry system where the rear half of the wing and the twin tail booms folds 70 degrees upward along a hinge running the length of the wing; increasing drag while remaining stable. SpaceShipOne completed the first crewed private spaceflight in 2004. That same year, it won the US$10 million Ansari X Prize and was immediately retired from active service. Its mother ship was named "White Knight". Both craft were developed and flown by Mojave Aerospace Ventures, which was a joint venture between Paul Allen and Scaled Composites, Burt Rutan's aviation company. Allen provided the funding of approximately US$25 million.

Burt Rutan American aerospace engineer

Elbert Leander "Burt" Rutan is a retired American aerospace engineer and entrepreneur noted for his originality in designing light, strong, unusual-looking, and energy-efficient air and space craft. He designed the record-breaking Voyager, which in 1986 was the first plane to fly around the world without stopping or refueling, and the Virgin Atlantic GlobalFlyer, which in 2006 set the world record for the fastest and longest nonstop non-refueled circumnavigation flight in history. In 2004, Rutan's sub-orbital spaceplane design SpaceShipOne became the first privately funded spacecraft to enter the realm of space, winning the Ansari X-Prize that year for achieving the feat twice within a two-week period.

Mojave Air and Space Port Facility located in Mojave, California

The Mojave Air and Space Port, also known as the Civilian Aerospace Test Center, is in Mojave, California, United States, at an elevation of 2,801 feet (854 m). It is the first facility to be licensed in the United States for horizontal launches of reusable spacecraft, being certified as a spaceport by the Federal Aviation Administration on June 17, 2004. The facility covers 2,998 acres and has three runways.

Rutan VariEze

The Rutan VariEze is a composite, canard aircraft designed by Burt Rutan. It is a high-performance homebuilt aircraft, hundreds of which have been constructed. The design later evolved into the Long-EZ and other, larger cabin canard aircraft. The VariEze is notable for popularizing the canard configuration and moldless composite construction for homebuilt aircraft.

Scaled Composites Proteus Experimental aircraft

The Scaled Composites Model 281 Proteus is a tandem-wing High-Altitude Long Endurance aircraft designed by Burt Rutan to investigate the use of aircraft as high altitude telecommunications relays. The Proteus is actually a multi-mission vehicle, able to carry various payloads on a ventral pylon.

Rutan Boomerang

The Rutan Model 202 Boomerang is an aircraft designed and built by Burt Rutan. The design was intended to be a multi-engine aircraft that in the event of failure of a single engine would not become dangerously difficult to control due to asymmetric thrust. The result is an asymmetrical aircraft with a very distinct appearance.
