Harmon Rocket HR-2 Rocket II / Rocket III

TerryLeave a comment

The Rocket II is a modified Van’s two place RV-4.
The kit to build a Rocket II from John Harmon is an extension of RV-4 kit which is purchased from Van’s.
With the intended use of bigger engines the altered fuselage is wider and the length 18 inches longer.
The modified wing was tested by an independent engineering facility. A unique modification is titanium for the gear legs which provide a difference in feel when landing and also doesn’t shimmy during ground operations.
The HR2 is not a quickbuild kit as many builders of the Rocket prefer to be more involved in the aircraft building process and express a preference of some minor fitting and trimming. An economy cruise speed of 215 mph at 55 is average for a Rocket II with a LYC.10-540 -C4B5/250 hp. 2575 rpm. while there is one Rocket that has a 340+ horsepower and can cruise at 275 mph.

Harmon Mr America

Harmon chose the long-established combination of a welded steel-tube fuselage and tail surfaces, with wood spar and rib wings. In addition, the wing may be easily removed for storage and towing. The entire aircraft can be built with hand tools except for the use of a welding rig. Mr. America’s powerplant is a nearly stock 1600-cc Volkswagen engine bored to 1650. The engine develops an honest 60 hp, to pro¬duce what is said to be rapid acceleration on takeoff to around 800 fpm at 90 mph during initial climb.

The translation of this open-cockpit sport plane’s name is “The Thunderclap” It was the airframe of this plane which was used as the foundation for “Mr. America.” Both share similar wings, fuselage, tail unit and landing gear. The wings are a wire-braced, shoulder type with two simple beam spars. As with the Mr. America, seating is for one, behind a modified Volkswagen engine turning a two-blade wooden prop.

Harmening’s High Flyers High Flyer

TerryLeave a comment

Introduced in 1988, the Harmening High Flyer powered parachute was designed to comply with the US FAR 103 Ultralight Vehicles rules, including the category’s maximum empty weight of 254 lb (115 kg). The aircraft has a standard empty weight of 247 lb (112 kg). The aircraft was designed to be a single-place or optionally two-seater. The base model High Flyer features an MK Superfit rip-stop nylon parachute-style high-wing, tricycle landing gear and a single 45 hp (34 kW) 2si 460-F engine in pusher configuration. Variants use other engines.

High Flyer Executive

The aircraft is built from a combination of bolted 6061-T6 aluminium, welded 4130 steel tubing and mild steel. In flight steering is accomplished via foot pedals that actuate the canopy brakes, creating roll and yaw. On the ground the aircraft has lever-controlled nosewheel steering. The main landing gear incorporates sprung steel suspension. The aircraft was factory supplied in the form of an assembly kit that required 30–40 hours to complete.

All kits were manufactured in the USA, and includes the engine and 3 blade propeller. FAR 103 legal, the High Flyer Standard converts from single to two place in 10 minutes.

By 1998 the company reported that 75 kits had been sold and 75 aircraft were completed and flying, the cost in 2001 was US$9,500.

The production by Harmening’s High Flyers of Genoa, Illinois, USA, ended when the company went out of business in circa 2008.

Harbin Y-12 / Hafei Aviation Industry Y12

TerryLeave a comment

In July 1982 it was reported that the Harbin Aircraft Works had developed a turbine-powered version of the Y-11, with PT6A-110 turboprops. A prototype was reputed to have flown. With a gross weight of 12,125 lb / 5500 kg, the maximum payload is 3748 lb / 1700 kg, and the Y-11T is estimated to have a max speed of 175 mph / 282 kph and a max range of 876 miles / 1410 km.

Developed from the earlier piston-engined Y-11, the twin-PT-6A-powered Y-12 has an enlarged cabin to accommodate up to 17 passengers. A first production batch of 18 aircraft was scheduled for completion by the end of 1986.

Harbin Y-12 Article

The Y-12 prototype first flew in 1982, and there have been three series production versions

Y12 (I)
Initial version with 500 shp PT6A-11 engines, 93” diameter propellers,
leading edge slats, seating for 17 passengers and a MTOW of 5000 kg.

Y12 (II)
Later production version with higher-rated 600 shp PT6A-27 engines, plain leading edge, 98” diameter propellers and MTOW increased to 5300 kg. The UK CAA issued Type Certificate FA49 for this variant in 1990 and examples are in operation in Malaysia and Fiji.

Y12 (IV)
Improved model with sweptback wingtips, redesigned seating for 18-19 passengers and max. weight increased to 5700 kg. The Canadian Aerospace Corporation markets a version of the aircraft under the Twin Panda name as a DHC-6 replacement.

The Sri Lankan Air Force ordered six Y-12 turboprop utility transports from China in 1986, and at least two have been delivered to the Chinese Air Force for aerial survey work.

The Y12 was originally produced by Harbin Aircraft Manufacturing Corporation (HAMC), and under Chinese commercial arrangements is marketed by the China Aviation Technology Import and Export Company (CATIC). HAMC has subsequently been reorganised in 1999 as Hafei Aviation Industry Co. Ltd (HAI), responsible for the Y12 and other sub-contract work.

Federal Aviation Administration Type Certificate: A00006WI applies to the Hafei Aviation Industry Company Limited Y12 IV.

Created in 1952 from the Mansyu Hikoki Seizo Kabushiki Kaisha of Manchuria. Began the H-6 bomber program in 1957, initially assembling two Tu-16s from Soviet supplied components, the first flying in September 1959, but in 1961 this program was transferred to Xi’an. Manufactured the H-5 jet bomber from 1966 to the 1980s, based on the Soviet llyushin II-28. Developed and still produces the Y-11 (first flown about 1975) and Y-12 (first flown June 1984) general-purpose transports and Z-9 Haitun twin-turboshaft helicopter as license-produced Eurocopter Dauphin 2. Was pursuing development of a new helicopter in 1999, and is a partner in the Colibri EC 120 B helicopter program . Also produced two prototype (one static) and five production SH-5 anti-submarine amphibians (one civil, tested as a firebomber).

In 1998, the core company of Harbin Aircraft Industry Group (HAIG) was under under AVIC II and occupied a 514 ha (1.270 acre) site, including 350,000 sq.m of workshop space. The workforce in 1998 numbered approximately 18,000.

Harbin partnered with Eurocopter and Singapore Technologies Aerospace in the Eurocopter EC 120 Colibri programme, for which it builds the cabin.
