Étienne Dormoy
Étienne Dormoy (10 February 1885, in Vandoncourt, France – 28 February 1959, in San Diego, USA) 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, NJ), wherein he designed the first monocoque fuselage aircraft produced in USA. With this monoplane, Harold D. Kantner won the NY 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, CA. Dormoy returned to France at the beginning of World War I, working for SPAD. In 1917, he joined the French industry delegation in the United States for SPAD technology transfer to Curtiss Aeroplan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aerial Application
Aerial application, or what is informally referred to as 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 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 ...

Convair
Convair, previously Consolidated Vultee, 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 2020. The company also entered the jet airliner business with its Convair 880 and Convair 990 designs. These were smaller than contemporary aircraft like ...

Autogyro
An autogyro (from Greek and , "self-turning"), also known as a ''gyroplane'', is a type of rotorcraft that uses an unpowered rotor in free autorotation to develop lift. Forward thrust is provided independently, by an engine-driven propeller. While similar to a helicopter rotor in appearance, the autogyro's rotor must have air flowing across the rotor disc to generate rotation, and the air flows upwards through the rotor disc rather than down. The autogyro was invented by Spanish engineer Juan de la Cierva in an attempt to create an aircraft that could fly safely at low speeds. He first flew one on 9 January 1923, at Cuatro Vientos Airfield in Madrid. The aircraft resembled the fixed-wing aircraft of the day, with a front-mounted engine and propeller. Cierva's autogyro is considered the predecessor of the modern helicopter. The success of the autogyro garnered the interest of industrialists and under license from Cierva in the 1920s and 1930s, the Pitcairn & Kellett compan ...

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 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. Variants * LA-1 Bull Pup * LA-1A Bull Pup – version for competition flying with 28 ft wingspan * LA-1B Bull Pup – version for high-altitude flying with 32 ft wingspan * LA-1S Bull Pup – floatplane version Specifications (L-1) See also * Buhl CA-1 Airster ; Buhl Airsedan The Buhl AirSedan was a family of American civil cabin sesquiplane aircraft developed and manufactured by the Buhl ...

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 one, 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 A ...

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.
