"Gourdou-leseurre GL-432 carrier bomber
Gourdou-leseurre GL-432 carrier bomber (Designed by French Aviation technician Charles Edouard Pierre Gourdou and Jean Adolf Leseurre) was an aircraft that has developed from the GL-30 series. The GL-30 was a single-seat fighter that evolved from a racing aircraft, but the GL-430, which was completed in 1931, was designed to be a-single seat bomber. (therefore, the prototype aircraft was called as GL-430. 01B1 (B1 is a symbol representing a single –seat) bomber).
GL-430, which had a parasol type high wing, strengthened the prop that supporting the wing on the fuselage, but other parts were similar to GL-32, which is the main production type of the GL-30 series. GL-430 had duralumin steel pipe construction covered with fabric, it was possible to dive bombing with a 50kg bomb under the fuselage.
GL-430 prototype aircraft that had landing hook, strengthen the structure of the rear fuselage, a long-term test operation was carried out by the French Navy.
In 1935, the French navy ordered four GL-432BP1 (BP1 represents a single-seat dive bomber) which became a pre-production aircraft.
The GL-432 was more strengthened than the prototype aircraft, and the bladder was installed to float the aircraft at the time of crash landing on water for offshore operation. The GL-432 amount of the bomb was larger than the prototype aircraft and can be equipped with a 225 kg bomb for the Navy.
From 1936, French Navy conducted operation test using GL-432, but the Second World War broke out before it started mass production, so it ended without leaving the prototype.
Also GL-482 single seat fighter and GL-531 carrier bomber were product experimentally, but these aircraft have also been planned to discard France surrender.
These aircraft were terminated due to French surrender."

"The Gourdou-Leseurre GL-482 was a single - engine gullwing fighter developed by the French company Gourdou-Leseurre in the early thirties and remained at the prototype stage.
Made on a specification issued by the Service technique de l'aéronautique (STAé) on behalf of the Aéronautique Militaire , the air component of the Armée de terre (the French army ), evaluated together with other eleven competitors was deemed unsuitable by preferring the Dewoitine D.500 , consequently its development was abandoned. It was the last fighter designed by the French company before its closure.
History of the project
In 1930, when the legacy Chasse "Jockey", also known as Plan Caquot , a program for the creation of a light fighter, was deemed unsuccessful, to remedy the need to replace the fleet of aircraft now inadequate, the Service Technique de l'Aéronautique (STAe ) issued a specific C1, ie related to a new single-seat fighter model. The requirements, already expressed in 1928 , were related to an aircraft with excellent visibility, cell with a robustness coefficient of 16, maximum reachable speed of at least 327 km / h at 3 500 m and an armament comprising two Vickers 7 caliber machine guns , 7 mm built under license by the Manufacture d'Armes de Châtellerault (MAC). A subsequent modification, dated 26 January 1931, specified the need to use an aeronautical engine with a displacement between 26 and 30 L equipped with a mechanical compressor bringing the maximum speed to 350 km / h at 4 000 m.
In the competition the main national aeronautical companies answered, presenting no less than 10 projects, realized in 12 different prototypes , almost all designed around the Hispano-Suiza 12Xbrs , a 12-liter 26 L V-cylinder capable of delivering a power of 650 hp (485 kW ) at an altitude of 4 500 m (14 765 ft ), chosen for its proven reliability and contained front surface compared to the models then available.
The Gourdou-Leseurre was among the last to present its proposal, the GL-482, a model that re-proposed the setting of the previous models developed by the company, single-engine in designing a classic single-tailed fletching and fixed cart, but although it maintained the veiling monoplana , unlike the previous equal role made by the company, abandoned the sunshade configuration to adopt a gull-wing configuration, a solution intended to revive the advantages theorized by the Polish Zygmunt Puławski who first adopted it to equip an aircraft and which made it possible to combine the greater stability of a high wing with improved visibility by the pilot and already adopted, despite the inevitable differences linked to the different paternity of the project, by the competitor Loire 43 .
The prototype was taken to the air for the first time in February 1933 but presented to the French army examining committee failed to achieve the performance required by the specification, also expressing performances generally lower than the competition.
The Gourdou-Leseurre decided to abandon its development and the model was the last hunt developed by the company. "
