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 MH02

TerryLeave a comment

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.

Hollman HA-2M Sportster

TerryLeave a comment

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

Holleville RH-1 Bambi

TerryLeave a comment

The French-built Holleville RH.1 Bambi was designed and built by Monsieur Roger Holleville and flown for the first time on July 27, 1953. It is a side-by-side two-seat aircraft and was unusual at the time to be among self-build types to make extensive use of synthetic resins and sandwich construction. It was originally intended to make construction plans available to clubs and groups, however, the design was sophisticated and plans to market kits were abandoned.

The Bambi is basically of wooden construction and the exceptional cleanliness of the overall design results in an outstanding performance on a 65 h.p. engine.

The aircraft has a low-wing layout and a fixed tail-wheel undercarriage.

The Bambi was initially operated by its designer from Guyancourt airfield to the west of Paris. By 1964 it was owned by Monsieur Gerard Chaplain and based at St Dizier.

It has visited the United Kingdom to attend light aircraft rallies including at Biggin Hill airport in Kent in 1967. The sole Bambi received a 90 hp Continental C90-8F engine in the early-1980s. In October 2001 the aircraft was donated to the GPPA (Groupement pour la Préservation du Patrimoine Aéronautique) which is operating the Musée Régional de l’Air at Angers Loire Aéroport, Marcé near Angers, France. The Bambi is preserved in airworthy condition in the Musee Regional de l’Air at Angers Aerodrome, 20 km north east of the town.

Holcomb Perigee

TerryLeave a comment

Due to other events, notably the Bullet 2100 project and Molt’s declining health, the Micro-IMP was not developed further. Jerry Holcomb went on however to develop, build and fly a refinement of the Micro-IMP design which he named the “Perigee”.
The Perigee, which was designed by Jerry Holcomb of Perigee Associates and initially called the Ultra Imp, first flew in April 1987 and is based on the TPG form of construction pioneered on the Aerocar Micro-Imp. This is a version of the same company’s Mini-Imp, which clearly provided the conceptual starting point for the Perigee.
The TPG (Taylor Paper Glass) form of construction was developed by Moulton B. Taylor, president and general manager of Aerocar, which was created in 1948 to develop Mr Taylor’s extraordinary flying car concept. TPG is a paper core (with metal inlays to accommodate compression loads) covered in glassfibre in a matrix of polyester resin and covered with ripstop Dacron fabric. The Mini-Imp and Micro-Imp both have retractable tricycle landing gear, but the Perigee uses fixed tailwheel landing gear with cantilever main legs ending in elegant speed fairing round the wheels. The need to accommodate a tailwheel led to an alteration of the Y-shape tail unit by comparison with the Aerocar types: in the Perigee it is turned through 1800 so that the vertical surface is at the bottom with the tailwheel attached to its lower edge.
The streamlined fuselaqe is of composite construction with spruce longerons, TPG bulkheads, cockpit floor, tailcone and side skins, a glassfibre nose and some aluminium alloy components. The braced high-set wing has an aluminium alloy/TPG main spar, a spruce/TPG rear spar, wood main ribs, TPG nose ribs, a glassfibre leading edge and fabric covering aft of the main spar. The full-span flaperons are of aluminium alloy sheet over polystyrene foam. The three tail surfaces are similar to the wing in basic construction, but have no wood in them. Propulsion is the task of a twin-blade pusher propeller behind the tail unit, and this is driven by an extension shaft running aft from the engine located behind the cockpit.
Fixed-gear, strut-based monoplane with Y tail, pusher engine. Wings fold for towing on highway. Optional retractable gear, cantilever wing. Powerplant: Cuyuna 430 drives controllable pusher prop. Landing gear: Fixed taildragger.

Holbrook 1910 Aeroplane

TerryLeave a comment

High-wing monoplane designed by Arthur Erritt Holbrook and built by the Holbrook Helicopter Aeroplane Co. in Joplin, Missouri. At around the time of the founding of his company, Holbrook also filed (January 19, 1910) to patent an Aeroplane; rather a tandem wing monoplane fitted with both tractor propeller and vertical rotors – hence the name of the firm. Four years later, on February 10, 1914, Holbrook was finally granted US Patent 1,086,916 for his invention. It is reasonable to assume that this photographed machine, with shafts protruding above the wing, was a “first draft” to be augmented to a form visible in the patent of Holbrook, where two rotary propellers are visible. After its appearance in 1910, Holbrook’s aeroplane was never heard from again.
