Blackburn Botha










First flight
28 December 1938
Introduced
12 December 1939
Retired
September 1944



Number built
580

The Blackburn B.26 Botha was a competitor to the Bristol, and entered service with the RAF in 1939. It was underpowered and was quickly withdrawn from operations.



In service, the Botha proved to be severely underpowered and unstable and there were a number of fatal crashes in 1940. Both airframe and engine were subject to further development work, but it was decided to withdraw the type from front-line service. At this point, the Air Staff made the ill-advised decision to transfer the surviving aircraft to training units, which inevitably resulted in further casualties.


The type was finally retired in September 1944. In total, 580 aircraft were built.

Performance

  • max speed: 260 knots (482 km/h)
  • service ceiling: 20,000 ft (6,100 m)

The Bird of Prey aircraft was developed intending to demonstrate stealth technology . it was a low cost program ( a price of $67 million) compared to many other programs . It developed technology and materials which would later be used on Boeing's X-45 unmanned combat air vehicle. It is characterized as a technology demonstrator.Development of the Bird of Prey began in 1992 by McDonnell Douglas's Phantom Works division for special projects. The first flight was in 1996, and 39 more were performed through the program's conclusion in 1999.The Bird of Prey is designed to prevent shadows and is believed to have been used to test active camouflage , which would involve its surfaces changing color or luminosity to match the surroundings.

The AASI Jetcruzer

The AASI Jetcruzer
Country of origin :United States of America

Capacity :

Typical accommodation for six including pilot. Can be configured for ambulance, cargo and other utility work. Optional aft lavatory.
Production :

450 - 3 were built. 500 - by November 2001, 2 had been converted from 450s, 1 new one was built, and 197 were on order. Basic unit price (2001) $US1.495.000.
Type :Business and utility transport
History :

The innovative Jetcruzer 500 is designed to be a high speed low cost single engine corporate turboprop and is the product of California based Advanced Aerodynamics and Structures Inc (AASI).
The Jetcruzer 500 is based on the smaller, unpressurised Jetcruzer 450. Early design work for what would become the Jetcruzer 450 began in 1983. Construction of an Allison 250-C20S powered prototype began in 1988. It flew for the first time on January 11 1989.
The preproduction prototype first flew April 1991, and the first production standard Jetcruzer 450 on September 13 1992. When FAA Part 23 certification was granted on June 14 1994 the Jetcruzer became the first aircraft in the world to be certificated as spin resistant.
AASI elected not to place the 450 into production and instead focused its efforts on the pressurised 500. Initial work was on the 500P, which featured a modest 25cm (10in) fuselage stretch, but AASI instead decided to enlarge the design further. The definitive Jetcruzer features a 1.83m (6ft) fuselage stretch over the 450 (increasing cabin length by 90cm (3ft), plus a significantly more powerful PT6A66 turboprop driving a five (rather than three) blade prop, pressurisation to 30,000ft, an airstair entry door on the right hand side and additional cabin windows.
First flight of the prototype 500 (the modified preproduction prototype 450) was in August 22 1997, followed by the second prototype (the modified production 450) on November 7 1997.
Other notable Jetcruzer 500 design features include its canard configuration (which allows the main wing to be positioned further aft than normal, so the wing spars do not intrude into the cabin), lack of flaps (reducing pilot work load and manufacturing costs and saving weight), and optional EFIS avionics. Like the 450 the 500 will be certificated as spin resistant. The fuselage is made from composites while the wing and canard are aluminium.
On February 8 2002, AASI announced that it was taking over the Mooney assets, and that the name Mooney would be used for the combined companies. Headquarters, development, and marketing would remain at AASI's facility at Long Beach in California, but production of the Jetcruzer would be at Mooney's Kerrville, Texas plant.
The company is also working on the Stratocruzer 1250, a 13 place twin WilliamsRolls FJ-44 powered light corporate jet development.
