Chauviere Gyroptere

Lucien Chauviere, a propeller designer, built a machine dubbed the Gyroptere in 1927, based on the principles of a patent he had filed ten years earlier. It used a 170kW Renault engine to drive a four-blade rotor with flapping hinges and clutched to power a tractor propeller at the nose. To counter torque while the rotor was powered, control flaps mounted vertically on the fuselage sides vectored the slipstream. Testing of the 1,372kg aircraft did not progress very far before his available finances were expended.

Châtelain AC-5 Bijou

F-PHQO c/n 01

The AC-5 Bijou was one of several original homebuilt aircraft designed and built by Armand Châtelain in the 1950s and 1960s.

The sole AC-5 was initially powered by a 75 hp Minié 4DC-32 Horus engine, and was registered F-PHQO. It first flew on September 10, 1956. Later it was re-engined with one 65 hp Continental A65, the aircraft was still active in 2012.

Chassany Monoplane

Chassany built his Monoplane in France in 1910.

This Nieuport-like monoplane was displayed at 1910 Paris “Exposition de la Locomotion Aérienne”. It’s recognisable by the three-cylinder Viale engine and the arrangement of landing gear struts.

It was claimed to be the lightest plane at the show, having reached 90 km/h with only a 32 hp engine. It was also the cheapest, costing only 7,000 francs without engine.

Chase-Gouverneur 1911 Wrightsville Beach / Gouverneur

In July 1910 Harold M. Chase and Minor F.H. Gouverneur received a patent for a mechanism to stabilise and control aeroplanes. Their invention was a manually operated lever described as capable of being swung in any direction to transmit motion to other elements of the plane, apparently including on the wings. Three weeks later they won a second patent for rear wing panels (ailerons) that were controllable in flight by a cable or flexible cord, a device different enough from the 1906 Wright wing-warping patent.

On November 14, 1910, M. F. H. Gouverneur, vice-president of the Tide Water Power Company, and H. M. Chase, manager of the American Chemical and Textile Coloring Company, made the only public test flight of the airplane they built on Shell Island, sometimes called Moore’s Beach. More than 5,000 visitors crowded Wrightsville Beach four months earlier, when, on July 4, the pair had planned to attempt the first flight of their self-designed aircraft. Newspaper reports described the November flight, piloted by Mr. Chase, as having attained an altitude of about five feet, sustained for some distance, just long enough to demonstrate the plane’s ability to fly. The event carries the distinction of being the first airplane constructed in North Carolina and owned and flown by North Carolinians.

Designed and built by H. M. Chase and M. F. H. Gouverneur, Wilmington NC, USA, the 1911 Chase-Gouverneur “Wrightsville Beach” multiplane was similar to a Wright aircraft but built from aluminum.

It flew short hops at about five feet altitude on 10 November 1911, at Wrightsville Beach, Chase flew in a series of unannounced hops along the Shell Island beach at low tide.

In 1911 Gouverneur won a lawsuit for $380, with interest, against Boston’s Harriman Motor Works, apparently because its motor was unreliable.

In 1912 Gouverneur informed London’s Jane’s All the World’s Aircraft that he was now using the Gouverneur IV, a 25ft long monoplane with a 31 ft span, with pilot, it weighed 840 lb. According to Chase, his former patner hired an experienced pilot to fly one of his planes, apparently the Gouverneur IV, but the aviator crashed and “Gouverneur went no further”.

Chasle YC-12 Tourbillion

The Tourbillion (Whirlwind) is a single seat, amateur-built, light low-wing plane that comes from France.

Prototype Chasle YC-12 Tourbillion F-PMXQ nearing completion at Beynes 1965

Designed by Yves Chasle in 1964, the wooden prototype F-PMXQ first flew on 9 October 1965.

It is available in several models that differ only in their engine size. Most common is the 65-hp Continental. Airframe construction includes wood and fabric wings and a plywood-covered fuselage structure.

Plans no longer available.
