The de Glymmes DG X OO-AKV (c/n 01) was designed by engineer Raoul de Glymes of Hollebecque, Belgium, and fabricated in collaboration with Alfred Herrmann.
This two-seater aircraft was equipped with a Renard 100hp engine and was registered as OO-AKV in 1931.
In 1931, R. Van de Velde owner and pilot of the aircraft flew Brussels – Nuremberg – Vienna (1400 Km) in 9 flight hours with an average speed of 155 Km/H.
On August 22nd, 1931 the same pilot won the first place of a Belgian air raid organized by the “Aeroclub Royal de Belgique”.
The registration and the plane disappeared in 1935.
The first machine incorporating the S.C. Hart-Still wing was the 1937 Deekay “Knight” two seat cabin monoplane. The wings of this aircraft are in wood, but developments for the use of plastic materials was to be extended to the production aircraft of the company. One completed; scrapped during war.
The first of two unsuccessful aeroplanes designed and built by Établissement de Dion-Bouton, the car and motor company. Remotely resembled a Wright Flyer, with twin rudders at the rear, a single small tailplane, and a triplane elevator in front, but instead of wings, each side had four wing-segments set at 30 degrees dihedral. Four propellers were to be employed, driven by a 100 hp engine. Displayed incomplete at the Première Exposition internationale de la locomotion aérienne at the Grand Palais in Paris during September 25 – October 17, 1909, construction and/or testing was likely halted afterwards as nothing more was heard of this flying machine of Jules-Albert de Dion and Georges Bouton.
Emmanuel Honoré Decommines, known as Georges Decommines, was born in Ostend, Belgium, on 14 February 1879. His brother Louis Decommines helped him with the construction of this airplane. The tractor propeller was driven by a 25 hp Anzani, which was financed by his aunt. On the first flight attempt, on the morning of May 15, 1910 on the beach of Ostend, Belgium, refused to start and on the second threw a propeller blade through the fuel tank, causing a fire which burned both the plane and the pilot/builder, but both were able to recover and try again. After repair, the machine crashed while attempting to take off. The builder, with minimal damage this time, took the hint and scrapped it, but he would come back with another design the year after.
was a success and gave its first public demonstration flight at Monett on July 4, 1911, flown by Monett druggist Logan McKee. It then made an exhibition tour in Oklahoma and Texas.
The aeroplane made several straight away flights, going some distance, but hardly exceeding fifty feet in height, alighting in some pasture and returning to the grounds.” If I am reading this correctly, when McKee wanted to turn around, he landed and turned the plane around on the ground, then flew back to the fair grounds. Turning was by far the most dangerous maneuver in early flight, and making a plane that could turn safely was a major design challenge for early airplane builders. Either McKee was a very cautious pilot, or the DeChenne was a very limited aircraft. In any case, the DeChenne company received $1,000 for a two day exhibition at Caddo.
On October 6, 1911, Aero magazine carried a classified ad seeking a new pilot for the Dechenne, and on November 25, 1911, it carried an ad offering to sell the plane’s engine. “Cheap if taken soon. Reason, have closed for season and can make more by spring.” If the plane ever flew again after McKee, I have found no record of it. In February, 1913, Aero & Hydo magazine carried a “quitting business” ad offering to sell various assets of the DeChenne company.
Édouard Eugène Joseph Ghislain opened a workshop in Nieuport-Groenendyck, with his first monoplane coming out 1910. A second with characteristic curved wings appeared in 1911 and another in 1912. Although building three different monoplanes his firm was principally in propeller production. The works folded in 1914 with the beginning of the war.
Around 1902, Viscount Decazes and G. Besancon had conducted tests of a 6m diameter vertically mounted propeller in Paris for a planned concept that would have used two of these vertical thrusting propellers, in addition to fixed wings and a propeller for forward thrust. The “rotor” tested produced 67kg of lift at 60 rpm, requiring 10hp. Without a flight weight engine, however, Decazes would have to weight ten more years to build his idea. In 1912, Decazes built his prototype “Helicoplane” at the Loire et Olivier Aircraft plant, and it was tested the following year by Commandant Dorand at Villacoublay. It used two 50hp Gnome rotary engines, one for the co-axial four-bladed rotors and one for the propeller. Two wings in tandem had approximately 25sq.m surface area each. Although it was not intended to hover without a head wind, it was planned to have minimum speed of 18km/h. A transmission failure, however, ended the tests prematurely, prior to flight.
