Spectrum Aeronautical
Spectrum Aeronautical is a business jet developer based in Carlsbad, California with its development center located in Spanish Fork, Utah. An engine failure while flying a single-engine Stinson Voyager over the jungles of Honduras in 1958 nearly killed Spectrum CEO Linden Blue. After this incident he started to design aircraft that had multiple engines. Since approximately 2006, the company has been involved in the development of two very light jets, the Spectrum S-33 "Independence" and the S-40 "Freedom", which are to be constructed making extensive use of composite materials. The twin-engined single pilot aircraft are supposed to carry between five and nine passengers over distances between circa 3000 and 4000 kilometres, using about 40% less fuel than conventionally built planes. The certification dates of both planes have been postponed on several occasions, even more so after a setback in 2006, when the company's only prototype - a S-33 - crashed, causing the death of ...

Composite Material
A composite material (also called a composition material or shortened to composite, which is the common name) is a material which is produced from two or more constituent materials. These constituent materials have notably dissimilar chemical or physical properties and are merged to create a material with properties unlike the individual elements. Within the finished structure, the individual elements remain separate and distinct, distinguishing composites from mixtures and solid solutions. Typical Materials, engineered composite materials include: *Reinforced concrete and masonry *Composite wood such as plywood *Reinforced plastics, such as fibre-reinforced polymer or fiberglass *Ceramic matrix composites (composite armor, composite ceramic and metal matrices) *Metal matrix composites *and other Advanced composite materials (engineering), advanced composite materials There are various reasons where new material can be favoured. Typical examples include materials which are less ex ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spectrum S-33 Independence
The Spectrum S-33 Independence is a very light jet designed and built by Spectrum Aeronautical using a carbon fiber construction process that makes the airplane weigh about two thirds as much as a comparably sized aluminum-frame airplane. The aircraft is designed to cruise at 45,000 ft. at speeds up to 415 knots (Mach 0.72) and fly as far as 2000 nm (3700 km) while using about half the fuel of comparably sized aluminum-framed business aircraft. FAA and JAA Type Certifications of the S-33 Independence were expected to be completed in 2009, but were not. The company has provided no press releases to explain the long delay in gaining certification. The aircraft is reported to be able to accommodate 5–6 passenger seats, a full-sized private lavatory, and will have a maximum take-off weight of 7,300 lb., with a range of over 2,000 miles. The retail sales price of the aircraft, which is equipped with Williams FJ-33 engines is supposed to be US-$3.95 million. Th ...

Spectrum S-40 Freedom
The Spectrum S-40 Freedom was a business jet developed by Spectrum Aeronautical. The aircraft was first announced at the 2006 NBAA Conference in Orlando, Florida. Design and development The S-40 is expected to be classified as a very light jet, albeit it is planned to feature a cabin comparable to the Lear 60, Hawker 800, Phenom 300 and the Citation XLS, at a Maximum Take-Off Weight of less than . It will be built using a graphite-epoxy construction process that makes the aircraft one third the weight of comparably sized aluminium airplanes. The aircraft is designed to cruise at at speeds up to 435 knots (Mach 0.76) and fly as far as 4170 km - while consuming about 40% less fuel than conventionally built planes - using two GE Honda HF120 engines. The retail sales price of the aircraft is supposed to be US-$6.8 million. In May 2011 Spectrum president Austin Blue is quoted: "We are still trying to get the programmes advancing, but it is not easy" The aircraft is to be rele ...

Williams V-Jet II
The Williams V-Jet II was designed and built by Burt Rutan's Scaled Composites for Williams International as a test bed and demonstrator aircraft for Williams' new FJX-1 turbofan engine. Development Williams International had been building small turbofan engines for cruise missile applications since the 1950s, and had successfully entered the general aviation market in the late 1980s with the FJ44 engine. In 1992, NASA initiated a program, Advanced General Aviation Transport Experiments (AGATE) to partner with manufacturers and help develop technologies that would revitalize the sagging general aviation industry. In 1996, Williams joined AGATE's General Aviation Propulsion (GAP) program to develop a fuel-efficient turbofan engine that would be even smaller than the FJ44. The result was the FJX-2 engine, which produced thrust. Williams then contracted with Burt Rutan's Scaled Composites to design and build the V-Jet II, considered a Very Light Jet (VLJ), to use as a testbed a ...

Bell Eagle Eye
The Bell Helicopter Eagle Eye, Model 918, was an American tiltrotor unmanned aerial vehicle that was offered as one of the competitors in the United States Navy's VT-UAV (Vertical Takeoff - Unmanned Aerial Vehicle) program. Development The Eagle Eye program began in 1993 with the TR911X 7/8th scale prototype. The composite airframe was originally designed and built for Bell by the California research company ''Scaled Composites''. The two demonstrator aircraft were powered by an Allison 250-C20 turboshaft engine mounted in the center fuselage, with a transmission system driving a tilting rotor at the end of each wing. The aircraft had its maiden flight on March 6, 1998, and then entered a flight test program. Phase 1 (land-based operations testing) was completed in April 1998. Phase 2 (sea-based testing) started shortly after that. The first prototype was destroyed in an accident, but the second successfully completed the test program. These successes led to the entry into ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scaled Composites Proteus
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 a multi-mission vehicle able to carry various payloads on a ventral pylon. The Proteus has an extremely efficient design and can orbit a point at over 19,800 m for more than 18 hours. It is currently owned by Northrop Grumman. Design and development Proteus has an all-composite airframe with graphite-epoxy sandwich construction. Its wingspan of is expandable to with removable wingtips installed. Proteus is an "optionally piloted" aircraft ordinarily flown by two pilots in a pressurized cabin.

Beechcraft Starship
The Beechcraft Starship is a twin-turboprop six- to eight-passenger pressurized business aircraft produced by Beech Aircraft Corporation. Development Development of the Starship began in 1979 when Beech decided to explore designs for a successor to its King Air line of turboprops that would fly faster and carry more passengers. The design was originated by Beechcraft in January 1980 as Preliminary Design 330 (PD 330). Beechcraft President Linden Blue was the executive sponsor of the project at its inception. Max E. Bleck was the Beechcraft President who oversaw its subsequent production. C.R. Stoner, head of Beechcraft’s Experimental division, was the project manager. On August 25, 1982, Beech contracted with Scaled Composites to refine the design and build an 85% scale proof-of-concept (POC) aircraft. One of the significant changes made to the design by Scaled Composites was the addition of variable geometry to the canard. The POC aircraft first flew in August 1983. ...
