Enstrom Helicopter Corporation
The Enstrom Helicopter Corporation is an American helicopter aerospace manufacturer, based at the Menominee–Marinette Twin County Airport in Michigan, United States. The company was founded in 1959 by mining engineer Rudolph J. "Rudy" Enstrom, initially as the R.J. Enstrom Corp. The company was bought by the Chongqing Helicopter Investment Corporation in 2013 and went out of business in January 2022. Surack Enterprises purchased the company from bankruptcy in May 2022 with the intention of restarting production. History Enstrom began by attempting to design his own helicopter. His lack of training in this area meant that his first efforts were not outstanding, but his efforts were noticed by local Upper Peninsula businessmen, who decided to back him. They recruited several experienced aeronautical engineers, and the group was incorporated as the R.J. Enstrom Co. (1959). The company's first product was the piston-powered F-28 (1965). However, Enstrom had been removed fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lycoming HIO-390
The Lycoming IO-390 engine is a horizontally opposed, four-cylinder aircraft engine, manufactured by Lycoming Engines. There is no carburetted version of the engine, which would have been designated O-390 and therefore the base model is the IO-390. Design and development The engine was originally conceived in the 1970s as the IO-400-X, but the project was never pursued. The IO-390 family of engines, which Lycoming refers to as the IO-390-X, produce to . The IO-390 was developed from the similar IO-360 engine, to increase the O-360's cylinder bore. (Although the IO-390 cylinder assembly is not the same part number as the IO-580, the cylinder barrels of both have a 5.318 bore and 4.375 stroke dimension.) It features a tuned induction system, roller tappets and Slick Start ignition. The engine has a fuel injection system which meters fuel in proportion to the induction airflow with fuel vaporization taking place at the intake ports. The engine has a displacement of .

Enstrom 480
The Enstrom 480 is a small, light helicopter produced by the Enstrom Helicopter Corporation.Apostolo, Giorgio: ''The Illustrated Encyclopedia of Helicopters'', pages 64-65. Bonanza Books, New York, 1984. Design and development In the 1980s the Enstrom Helicopter Company was producing two helicopters, both powered by horizontally-opposed piston engines. When the United States Army revealed a requirement for a turbine-powered training helicopter, the company designed a larger, turbine-powered version of its 280 Shark. The proposed unit was designated TH28 (TH for "training helicopter" derived from the 28(0), since the Army's proposal was NTH, "new training helicopter"). The Army contract effort was not successful, but the company effort looked promising enough that management committed to continue with a commercial version, which was introduced in 1993. Its power was provided by the C20W variant of the Rolls-Royce Model 250 turboshaft engine. Design The 480 fuselage consists of a ...

Spitfire Mark I
__NOTOC__ The Spitfire Mark I was a utility helicopter built in the United States in the late 1970s and intended for series production.Taylor 1989, p.839Simpson 1998, p.234Taylor 1977, p.411 In essence, the Mark I was an Enstrom F-28 that was modified to use an Allison 250 turboshaft engine and geared transmission in place of the original piston engine and system of vee belts. The resulting powerplant installation was lighter and more compact, which allowed for additional cargo or fuel. Spitfire Helicopters' parent company, Fetsko Aviation Sales and Transportation began work on the prototype in January 1976, and on a number of pre-production aircraft in February 1977. Fetsko displayed a mockup of the concept at the National Maintenance and Operations Meeting at Reading, Pennsylvania in June 1976.Field and Goodman 1976, p.33 The prototype (registered ''N4890'') first flew in December 1978. By May 1979, Spitfire had supplemental approval for the turbine conversionLambert 1979, p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brantly B-2
The Brantly B-2 is an American two-seat light helicopter produced by the Brantly Helicopter Corporation. Design and development After the failure of his first design, the Brantly B-1, Newby O. Brantly decided to design a simpler and less complicated helicopter for the private buyer. The B-2 had a single main rotor and an anti-torque tail rotor and first flew on 21 February 1953. This was followed by an improved second prototype that first flew on 14 August 1956. The B-2A was introduced with a modified cabin, and the B-2B had a larger 180 hp fuel-injected engine. The B-2B has a three-bladed articulated main rotor and an all-metal fuselage, it can be operated with skid, wheel or float landing gear. The piston engine is fitted vertically in the fuselage behind the cabin. Operational history The basic design has remained in production for over 50 years. The United States Army ordered five B-2s (designated the YHO-3) to be evaluated in the Light Observation Helicopter competiti ...

Robinson R22
The Robinson R22 is a two-seat, two-bladed, single-engine light utility helicopter manufactured by Robinson Helicopter Company. It was designed in 1973 by Frank D. Robinson, and has been in production since 1979. Development The majority of flight testing was performed at Zamperini Field in Torrance, California. Flight testing and certification was performed in the late 1970s by test pilot Joseph John "Tym" Tymczyszyn and the R22 received FAA certification in March 1979. Due to relatively low acquisition and operating costs, the R22 has been popular as a primary rotorcraft trainer around the world and as a livestock management tool on large ranches in North America and cattle stations in Australia. The R22 has a very low inertia rotor system Greenspun, Philip.2005 Robinson R22 - owner's review" March 2010.

Robinson R44
The Robinson R44 is a four-seat light helicopter produced by Robinson Helicopter Company since 1992. Based on the company's two-seat Robinson R22, the R44 features hydraulically assisted flight controls. It was first flown on 31 March 1990 and received FAA certification in December 1992, with the first delivery in February 1993. The R44 has been the world's best-selling general aviation (GA) helicopter every year since 1999. It is one of the most-produced GA aircraft of the 21st century, with 5,941 deliveries from 2001 to 2020. Design The R44 is a single-engined helicopter with a semi-rigid two-bladed main rotor, a two-bladed tail rotor and a skid landing gear. It has an enclosed cabin with two rows of side-by-side seating for a pilot and three passengers. Tail rotor direction of rotation on the R44 is reversed compared to the R22 for improved yaw control authority. On the R44 the advancing blade is on the bottom.

Schweizer 300
The Schweizer S300 series (formerly Hughes 300, Schweizer 300, and Sikorsky S-300) family of light utility helicopters was originally produced by Hughes Helicopters, as a development of the Hughes 269. Later manufactured by Schweizer Aircraft, and currently produced by Schweizer RSG, the basic design has been in production for over 50 years. The single, three-bladed main rotor and piston-powered S300 is mostly used as a cost-effective platform for training and agriculture. Development Background In 1955, Hughes Tool Company's Aircraft Division (later Hughes Helicopters) carried out a market survey showing that there was a demand for a low-cost, lightweight, two-seat helicopter. The division began building the Model 269 in September 1955. The prototype flew on 2 October 1956, but it was not until 1960 that the decision was made to develop the helicopter for production. On 9 April 1959, the 269 received certification from the Federal Aviation Administration (FAA) and Hughes conti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
