Hutter H 17 / Goppinggen 5

The H 17 was designed by the Hutter brothers, Ullrich and Wolgang, in Salzburg, Austria. The ‘17’ indicated the glide ratio. They sold plan sets until they joined Schempp-Hirth, which then built about five as the Goppingen 5 with the addition of a windshield and main wheel. Many were built from plans worldwide and several are still flying. A post-war version was developed and marketed as the H 17 B with enclosed cockpit, lengthened fuselage and airbrakes. The H 17B has slightly increased span and empty and loaded weights increased about 50%. One H 17 belongs to the National Soaring Museum. The Vintage Sailplane Association has plans.

Hurlburt Hurricane / Camburn Special

The Hurlburt Hurricane NX1223 of 1947 was designed and built by Marge Hurlburt, Anna Logan, and Duke Caldwell as midget racer #85.

Powered by an 85hp Continental C-85, the Hurricane was barred from Goodyear competition because the event was restricted to male pilots.

1947

Owned by Anna Logan and Mildred Caldwell of Cleveland, Eugene ‘Joe’ Smith flew the Hurricane in 1947.

The craft was later named the Camburn Special after Marge’s death. Eventually it was flown as Camburn Special in some competitions by Eugene “Joe” Smith.

Hurel Aviette

On the Aviette, Hurel used an aerodynamic solution to a structural problem. On this plane stabilising surfaces were attached on mini-tail-booms behind each outer wing. Just as the effect of a tailplane is to tend to return the entire aircraft to a level attitude from a non-level attitude, so the effect of these surfaces is to tend to hold the wing-tips at a constant angle relative to the airflow. The conventional constructional techniques of the time were used, materials being spruce, Balsa and Melinex.

Hurel’s 1976 Aviette aircraft had a 137 feet (42 m) span and a 12 feet (3.7 m) diameter propeller.

The Aviette flew at Le Bourget, largely through national recognition of the designer’s contribution to industry throughout his working life.

In 1974 the Aviette recorded flights of 1100 yards (1000 m).

The French entry to the Kremer Prize, the Hurel Aviette, might have been going into a museum. Unfortunately, at the time of the 1973 Paris Air Show, the airplane had to be moved from its hangar. Exposed to the elements, it was promptly chewed up by a dog.

Huntington H-12 monoplane

The 1920 Huntington H-12 monoplane was a successful design powered with a motorcycle engine. Designed and built by Dwight Huntington of Hempstead, this was the first kit, or plan-built, lightplane professionally engineered in the United States.

With a wingspan of 20 ft, the wings were attached to the upper longerons, but downward vision was increased by windows in the sides of the cockpit. It was powered by a 15 hp Harley Davidson motorcycle engine.

Able to cruise a 60 mph, plans of the H-12 were sold through aviation magazines into the late 1920s.

The cost of construction, without motor, was well under $80.
