Étienne Dormoy
Étienne Dormoy (10 February 1885, in Vandoncourt, France – 28 February 1959, in San Diego, US) was an aeronautical engineer and a designer of aircraft. Biography Etienne Dormoy graduated in 1906 as an electrical engineer from Institut industriel du Nord ( École Centrale de Lille, France). He worked as an aircraft designer for Deperdussin ( Deperdussin Monocoque (SPAD)) in France. He met Harold D. Kantner in France in 1913. He was then seconded to Maximilian Schmitt Aeroplane & Motor Works (Paterson, New Jersey), wherein he designed the first monocoque fuselage aircraft produced in the US. With this monoplane, Harold D. Kantner won the ''New York Times'' race on 4 April 1914. The aircraft was re-engineered as a biplane with a 100 hp engine and tested for military applications at San Diego, California. Dormoy returned to France at the beginning of World War I, working for the Société Pour L'Aviation et ses Dérivés (SPAD). In 1917, he joined the French industry de ...

Aerial Application
Aerial application, or crop dusting, involves spraying crops with crop protection products from an agricultural aircraft. Planting certain types of seed are also included in aerial application. The specific spreading of fertilizer is also known as ''aerial topdressing ''in some countries. Many countries have severely limited aerial application of pesticides and other products because of environmental and public health hazards like Pesticide drift, spray drift; most notably, the European Union banned it outright with a few highly restricted exceptions in 2009, effectively ending the practice in all member states. Agricultural aircraft are highly specialized, purpose-built aircraft. Today's agricultural aircraft are often powered by turbine engines of up to and can carry as much as of crop protection product. Helicopters are sometimes used, and some aircraft serve double duty as water bombers in areas prone to wildfires. These aircraft are referred to as SEAT, or "single engine ai ...

Convair
Convair, previously Consolidated Vultee Aircraft Corporation, was an American aircraft-manufacturing company that later expanded into rockets and spacecraft. The company was formed in 1943 by the merger of Consolidated Aircraft and Vultee Aircraft. In 1953, it was purchased by General Dynamics, and operated as their Convair Division for most of its corporate history. Convair is best known for its military aircraft; it produced aircraft such as the Convair B-36 Peacemaker and Convair B-58 Hustler strategic bombers, and the Convair F-102 Delta Dagger and Convair F-106 Delta Dart interceptors. It also manufactured the first Atlas rockets, including the rockets that were used for the crewed orbital flights of Project Mercury. The company's subsequent Atlas-Centaur design continued this success and derivatives of the design remain in use as of 2025. The company also entered the jet airliner business with its Convair 880 and Convair 990 designs. These were smaller than conte ...

Consolidated Aircraft
The Consolidated Aircraft Corporation was founded in 1923 in aviation, 1923 by Reuben H. Fleet in Buffalo, New York, the result of the Gallaudet Aircraft Company's liquidation and Fleet's purchase of designs from the Dayton-Wright Company as the subsidiary was being closed by its parent corporation, General Motors.Yenne 2009, p. 15. Consolidated became famous, during the 1920s and 1930s, for its line of flying boats. The most successful of the Consolidated patrol boats was the PBY Catalina, which was produced throughout World War II and used extensively by the Allies.

Autogyro
An autogyro (from Greek and , "self-turning"), gyroscope, gyrocopter or gyroplane, is a class of rotorcraft that uses an unpowered rotor in free autorotation to develop lift. A gyroplane "means a rotorcraft whose rotors are not engine-driven, except for initial starting, but are made to rotate by action of the air when the rotorcraft is moving; and whose means of propulsion, consisting usually of conventional propellers, is independent of the rotor system." While similar to a helicopter rotor in appearance, the autogyro's unpowered rotor disc must have air flowing upward across it to make it rotate. Forward thrust is provided independently, by an engine-driven propeller. It was originally named the ''autogiro'' by its Spanish inventor and engineer, Juan de la Cierva, in his attempt to create an aircraft that could fly safely at low speeds. He first flew one on January 1923, at Cuatro Vientos Airport in Madrid. The aircraft resembled the fixed-wing aircraft of the d ...

Buhl Bull Pup
The Buhl LA-1 Bull Pup was a light sports airplane developed in the United States in 1930. It was a mid-wing wire-braced monoplane with fixed Conventional landing gear, tailskid undercarriage and an open cockpit for the pilot. Buhl developed the Bull Pup as a cheap aircraft through which the company hoped to remain in business as the onset of the Great Depression was felt. However, as the economic situation worsened, it became evident that there was no demand for even such a basic aircraft; when production ceased in 1932, all aircraft still in stock were sold off at half price as the company folded.

Buhl Airsedan
The Buhl AirSedan was a family of American civil cabin sesquiplane aircraft developed and manufactured by the Buhl Aircraft Company in the late 1920s. One example completed the first transcontinental non-stop roundtrip flight, made in 1929 by the CA-6 ''Spokane Sun-God'', and the first Pope to have flown did so in a Buhl Airsedan. Design and development The Airsedan series were designed by Etienne Dormoy following the departure of Alfred V. Verville from Buhl, with whom he had worked previously. Dormoy had worked with Deperdussin before World War I, flew combat operations during the war before returning to work with SPAD, travelled to the US to coordinate production of SPADs with Curtiss until the project was cancelled with the end of the war. He then worked with Packard on automobiles for a year in 1919 before working as a civilian with the United States Army Air Corps with Verville, who convinced him to work at Buhl.Bleneau, Les berlines Buhl (Première partie), p.2-3 ...

Buhl-Verville CA-3 Airster
The Buhl-Verville CA-3 Airster (also known as the J4 Airster, after its engine), was a utility aircraft built in the United States in 1926, notable as the first aircraft to receive a type certificate in the US, (i.e. A.T.C. No. 1) issued by the Aeronautics Branch of the Department of Commerce on March 29, 1927. It was a conventional single-bay biplane with equal-span unstaggered wings and accommodation for the pilot and passengers in tandem open cockpits. Marketed for a variety of roles including crop-dusting, aerial photography, and freight carriage, only a handful were built, some with water-cooled engines as the CW-3, and others with air-cooled engines as the CA-3 . One CA-3 placed second in the 1926 Ford National Reliability Air Tour. 1926 Ford Air Tour, piloted by Louis Meister, and another (designated the CA-3A) placed third in the 1927 Air Derby, piloted by Nick Mamer.
