Honeywell LF 507 / AlliedSignal LF 507 / Lycoming LF 507
The Honeywell LF 507 is a geared turbofan engine produced by Lycoming, AlliedSignal and then Honeywell Aerospace. The earlier ALF 502 was certified in 1980. The improved, higher-thrust LF 507 was used on the Avro RJ update of the British Aerospace BAe 146.

Honeywell
LHTEC (Light Helicopter Turbine Engine Company) is a joint venture between Rolls-Royce and Honeywell founded in 1985. The company was originally a partnership between the Allison Engine Company and AlliedSignal Aerospace . In 1995 Rolls-Royce acquired Allison, and AlliedSignal merged with Honeywell in 1999, and adopted its name.
Honda HF118 / GE Honda HF120
The GE Honda HF120 is a small turbofan engine for the light-business jet market.
The HF120 turbofan is the first engine to be produced by GE Honda Aero Engines. Developed from the Honda HF118, the HF120 was undergoing an extensive testing program, with formal certification testing scheduled to begin in late 2008. The engine has a wide-chord swept fan, two-stage low-pressure compressor and counter rotating high-pressure compressor based on a titanium impeller. Evolved from Honda’s HF118, the engine demonstrates a 2,050 lbf takeoff thrust. The engine touts environmental performance, striving to meet and exceed future environmental standards for business jet engines. Greater fuel efficiency and reduced emissions are two of the results of the engine’s lightweight design.

Honda HA-420 HondaJet
The HondaJet made its maiden flight in North Carolina in December 2003. Honda’s six seat business jet is powered by a lightweight low-emission turbine engine that has been in development since 1988.
It features a graphite composite fuselage, laminar flow wing and two Honda HF118 turbofans mounted on overwing pylons.
Delivery of the first plane is planned for the third quarter of 2012.

Honda MH02
At the Atlantic Aero FBO at Greensboro, North Carolina’s Piedmont Triad International Airport (KGSO), a team of engineers and technicians assembled a twin-engine very light business jet. This was the proof-of-concept (POC) prototype of what would become the HondaJet very light jet. The team’s work culminated on Dec. 3, 2003, when the POC took flight.
This was a relatively small team of engineers and technicians that had been working furiously for at least the last 10 months—and some much longer—in preparation for that day.
There were no electrical system drawings, only conceptual schematics, and they had to create them from scratch.
They had a very small group in the early days of the project in Greensboro and a larger team in Japan supporting them. Work hours during the design phase started early and extended into the evening, day after day. In three years, they accomplished a tremendous amount of work and overcame huge challenges with the limited staff getting the aircraft ready for its inaugural flight.
The second production jet to feature over-the-wing-mounted (OTWEM) turbofan engines, the HondaJet was the brainchild of Honda’s Michimasa Fujino. Fujino spent years exploring aircraft design, culminating in flight testing of the composite twin-engine MH02, which had two engines mounted directly on top of a wing attached to the top of the fuselage.
He eventually settled on the HondaJet OTWEM design because of its efficiency and the extra space it afforded in the aft cabin, but persuading the head office that this was the best configuration proved to be a huge challenge. It took more than two years to reach the point and finally the OTWEM configuration for HondaJet was fixed.
At midnight and, with the flight scheduled for 8 a.m., the aircraft was prepped and ready to go. However, back in at 5:30 a.m., firing up the aircraft to make sure everything was still okay before the preflight.
Michimasa Fujino’s first design was the MH02, which didn’t go into production.

Holmes KH-1 / JSH Scorpion
Designed and built entirely by Mr Kenneth Holmes, a meteorologist, this British high performance single seater is characterised by a very high aspect ratio (31.0) wing and a slim fuselage of minimum cross-sectional area; construction is largely of wood.
Design work on the KH-1 began in1968, construction commenced in the following year and the prototype flew for the first time on 24 November 1971. The cantilever shoulder wings are of largely wooden construction with single aluminium spars bonded by epoxy resin and also pop riveted to plywood webs. The spars and closely spaced ribs are covered by a pre-moulded plywood/balsa sandwich to the 50% chord line, by a 2mm thick plywood skin for a further 20% of the chord and with fabric for the remainder of the wing. Small-span trailing edge flaps also act as air brakes, but spoilers are not fitted. The fuselage is built of plywood frames and spruce longerons covered with a birch ply skin, and the landing gear consists of a retactable monowheel and a tail bumper. The tailplane is an all-moving surface with anti-balance tabs controlled by a spring trimmer in the cockpit, and the tall fin and rudder is unswept. A tail braking parachute is fitted for control during the approach and in short field landings.
A second example of the KH-1 named the JSH Scorpion was built by Mr John Halford and first flew in July 1977.

Hollman HA-2M Sportster
As part of his Aeronautical Engineering thesis research Martin Hollman designed a set of aluminum rotor blades for a two-place gyroplane. Having designed a practical rotor system for a two-place gyro, he moved on to the design of a gyroplane to go with the new blades. The result was the Hollmann Sportster, a two-place home-built gyroplane. Plans for the Sportster were made available, powered by a certified Lycoming engine.
The Sportster is designed for the homebuilder who has limited access to power tools. Ninety percent of the structure is bolted or riveted together, 2x2in aluminum tubing, and a minimum of machined parts are used. For convenience, the Sportster is designed to be towed behind a car.
Two average people, 350 pounds combined, can fly comfortably inside its nearly enclosed cockpit for up to 90 miles on a cross-country trip. A 130-hp Franklin, 135-hp Lycoming, or 150-hp Lycoming engine can be used. With the engine cut, the Sportster has a 1,000-fpm sink rate. The Sportster is now marketed by Aircraft Designs, Inc.
The Sportster has been in the air since 1974. Its side-by-side dual controls are ideal for flight training. It’s partially enclosed and uses a 160-hp Lycoming engine to reach top speeds of up to 100 mph. Well-detailed plans for the Sportster 2001: $535
