Scaled Composites (often called simply Scaled) is an American aerospace company founded by Burt Rutan and currently owned by Northrop Grumman that is located at the Mojave Air and Space Port, 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.

Company history[edit]

Scaled Composites was established in 1982 and purchased by the Beech Aircraft Corporation in 1985, as a result of the collaboration on the Starship project. In 1988, Beech's parent company, Raytheon, sold Scaled back to Rutan, who then sold it to Wyman-Gordon. After Wyman-Gordon was acquired by Precision Castparts Corp., Rutan and ten investors re-acquired the company as Scaled Composites, LLC. Northrop Grumman, a major shareholder in the company with a 40% stake, said it would acquire the company outright on July 20, 2007. Both companies said Northrop Grumman's acquisition would not affect Scaled Composites' strategy or involve replacing Burt Rutan as senior manager.[1][2] The acquisition by Northrop Grumman was completed on August 24, 2007.[3] Rutan retired in April 2011.[4]

Early projects[edit]

Before forming Scaled Composites, Burt Rutan had designed several aircraft for amateur builders, including the VariEze, often considered one of general aviation's most innovative designs.[citation needed] He also designed the Beechcraft Starship, which was, however, a commercial failure. These aircraft were distinctive because of their canard configuration, winglets and pusher propellers.

Before SpaceShipOne, Rutan was best known for his Voyager aircraft, which his brother, Dick Rutan, and Jeana Yeager flew around the world without refueling in 1986. In 2005, the single-jet Global Flyer was flown by billionaire adventurer Steve Fossett on the first solo non-stop, non-refueled flight around the world, and later in the longest flight in history: 41,467.53 km (25,766.73 mi).

Although their role was not widely publicized, Rutan and John Roncz, who had provided aerodynamics support to a number of previous Rutan projects including Starship, helped design, and Scaled manufactured, the double slotted wing mast for the Stars & Stripes catamaran for Dennis Conner's entry in the 1988 America's Cup.[5]

The company announced in April 2003 that it was working on a privately funded spacecraft, in an attempt to win the Ansari X PRIZE for the first private, manned spaceflight. This experimental rocket-powered spacecraft was given the name SpaceShipOne. On December 17, 2003, they announced SpaceShipOne's first supersonic flight, the first flight of its kind by a privately funded aircraft. SpaceShipOne successfully made this flight, reaching 68,000 feet (21,000 m) and 930 mph (Mach 1.2). The craft was taken aloft by the White Knight carrier aircraft. On the same day, Paul Allen, one of the founders of Microsoft, confirmed publicly the rumors that he was the angel investor behind the SpaceShipOne venture.

On April 1, 2004, the U.S. Department of Transportation issued the company what it called the world's first license for a sub-orbital manned rocket flight.[6] The license was approved by the Federal Aviation Administration's Office of Commercial Space Transportation, which has backed licenses for more than 150 commercial launches of unmanned launch vehicles in its 20 years, but never a license for manned flight on a sub-orbital trajectory. The Mojave Airport, operating part-time as Mojave Spaceport, is the launch point for SpaceShipOne. SpaceShipOne performed the first privately funded human spaceflight on June 21, 2004. Flight 16P on September 29, 2004 and Flight 17P on October 4, 2004 won the X-Prize for Scaled Composites and SpaceShipOne.

Stratolaunch Carrier Aircraft[edit]

Scaled Composites Model 351 (nicknamed the "Roc"), is being built for Stratolaunch Systems to provide a platform from which air-launch space missions can be staged.[7] With a wingspan of 117 m (385 ft), the design has the longest wingspan of any airplane to date (July 2015).[8]

In August 2015, Scaled Composites president Kevin Mickey stated the company has so far assembled "roughly 200,000 pounds of composite structure" for the vehicle and if put on a football field, "its wingtips would extend beyond the goalposts by 15 feet on each side."[9]

Each of the twin fuselages of the aircraft is 238 feet (73 m) long and will be supported by 12 main landing gear wheels and two nose gear wheels. It will require 12,000 feet of runway to lift-off.[10]

Rutan Aircraft Factory aircraft[edit]

Burt Rutan created Rutan Aircraft Factory to market a commercial variation of his Model "VariViggen" prototype" he began building in his garage in 1968 which he called The Model 32, also known as the VariViggen SP. This model which utilized a slightly longer fuselage, larger span and winglets in order to increase efficiency. The Rutan Aircraft Factory sold over 600 plan sets for the VariViggen to homebuilders, and eventually about 20 of the aircraft were built. Following the crash of one in New Brunswick, Canada in September 2006 due to wing tank fuel contamination,[11] fewer than five are currently still flying. The prototype aircraft, N27VV, was donated to the EAA AirVenture Museum in 1988.

Accidents and incidents[edit]

  • On July 26, 2007, an explosion occurred during testing of SpaceShipTwo's systems, killing three employees and injuring three more.[19]
  • On October 31, 2014, the SpaceShipTwo VSS Enterprise broke apart during an in-flight powered test. The incident killed one pilot and severely injured the other, resulting in the total loss of the vehicle; both pilots were Scaled employees.[20][21] On July 28, 2015, the NTSB released the final report on its investigation of the incident, concluding that for an unknown reason the pilot had released the "Feather" of SpaceShipTwo prematurely, leading directly to the craft's disintegration.[22]
