L-1 Vigilant
The Stinson L-1 Vigilant (company designation Model 74) is an American liaison aircraft designed by the Stinson Aircraft Company of Wayne, Michigan and manufactured at the Vultee-Stinson factory in Nashville, Tennessee (in August 1940 Stinson became a division of Vultee Aircraft Corporation). The aircraft was operated by the United States Army Air Corps as the O-49 until 1942. Design and development The Vigilant was designed in response to a 1938 United States Army Air Corps design competition for a two-seat light observation aircraft. After the German-manufactured Fieseler Storch was demonstrated at the 4th International Air Meet in Zurich, Switzerland in 1937, the Air Corps Material Division at Wright Field initiated a feasibility study for the creation of a similar aircraft. The development program was approved in January 1938, design and performance specifications were determined in April 1938, and a Circular Proposal for a formal design competition was released to manufactu ...

Stinson Aircraft Company
The Stinson Aircraft Company was an aircraft manufacturing company in the United States between the 1920s and the 1950s. History The Stinson Aircraft Company was founded in Dayton, Ohio, in 1920 by aviator Edward Stinson, Edward “Eddie” Stinson, the brother of aviator Katherine Stinson. After five years of business ventures, Eddie made Detroit, Michigan the focus of his future flying endeavors while still flying as a stunt pilot, earning $100,000 a year for his efforts — a huge sum in those days. Stinson found Detroit's business community receptive to his plans to develop his own airplane. Alfred V. Verville and a group of local businessmen — the Detroit Board of Commerce's Aviation Committee — supported Stinson's plans to establish the Stinson Aircraft Syndicate in 1925, and provided $25,000 to design and build a prototype, an enclosed cockpit, 4-place biplane, powered by a Wright Whirlwind J-4 air-cooled radial engine test flighted at Packard Field in Roseville, ...

Boundary Layer Control
In engineering, boundary layer control refers to methods of controlling the behaviour of fluid flow boundary layers. It may be desirable to reduce flow separation on fast vehicles to reduce the size of the wake (streamlining), which may reduce drag. Boundary layer separation is generally undesirable in aircraft high lift coefficient systems and jet engine intakes. Laminar flow produces less skin friction than turbulent but a turbulent boundary layer transfers heat better. Turbulent boundary layers are more resistant to separation. The energy in a boundary layer may need to be increased to keep it attached to its surface. Fresh air can be introduced through slots or mixed in from above. The low momentum layer at the surface can be sucked away through a perforated surface or bled away when it is in a high pressure duct. It can be scooped off completely by a diverter or internal bleed ducting. Its energy can be increased above that of the free stream by introducing high velocity a ...

Stinson L-5 Sentinel
The Stinson L-5 Sentinel is a World War II-era liaison aircraft used by the United States Army Air Forces (USAAF), U.S. Army Ground Forces, U.S. Marine Corps and the British Royal Air Force. It was produced by the Stinson Division of the Vultee Aircraft Company (Consolidated-Vultee from mid-1943). Along with the Stinson L-1 Vigilant, the L-5 was the only other USAAF liaison aircraft that was exclusively built for military use and had no civilian counterpart other than the prototype. Design and development The origins of the L-5 can be traced to the prewar civilian Stinson HW-75. This 75 horsepower civilian high-wing design was built by the Stinson Aircraft Company at Wayne, Michigan and first flew in 1939. It was marketed as the Model 105 and was first introduced to the public at the New York World's Fair. The three-place HW-75 featured two side-by-side seats and a third "jumpseat" in back on which a small passenger could sit facing sideways. Economical, spin resistant and ea ...

Taylorcraft L-2
The Taylorcraft L-2 Grasshopper is an American observation and liaison aircraft built by Taylorcraft for the United States Army Air Forces in World War II. Design and development In 1941 the United States Army Air Forces ordered four Taylorcraft Ds with the designation YO-57. They were evaluated in the summer of 1941 during maneuvers in Louisiana and Texas where they were used for support purposes such as light transport and courier. General Innis P. Swift, commander of the 1st Cavalry Division, coined the 'grasshopper' name after witnessing a bumpy landing. This led to a production order under the designation O-57 Grasshopper. In March 1942, the designation was changed to L-2 Grasshopper. In World War II, the Army Ground Forces began using the L-2 and other liaison aircraft in much the same manner as the observation balloon was used in France during World War I—spotting enemy troop and supply concentrations and directing artillery fire on them. It was also used for l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aeronca L-3
The Aeronca L-3 group of observation and liaison aircraft were used by the United States Army Air Corps in World War II. The L-3 series were adapted from Aeronca's pre-war Aeronca 50 Chief, Tandem Trainer and Chief models. Design and development In 1941, the United States Army Air Corps ordered four examples of the Aeronca Chief family, Aeronca 65 TC Defender, designated YO-58, for evaluation of the suitability of light aircraft for observation and liaison purposes. (It also placed similar orders with Piper Aircraft, Piper and Taylorcraft Aircraft). Service tests during the US Army's annual maneuvers proved successful, and resulted in large orders being placed. In 1942, the O-58 was redesignated L-3.Swanborough and Bowers 1963, p. 31.Mondey 1996, p. 8. When American forces went into combat after Attack on Pearl Harbor, Pearl Harbor, the Army Air Force used the L-3 in much the same manner as observation balloons were used during World War I—spotting activities and directing ar ...
