A liaison aircraft (also called an army cooperation aircraft ) is a small, usually unarmed aircraft primarily used by military forces for artillery observation or transporting commanders and messages.
5-490: The Bristol Boarhound was a British army cooperation and liaison aircraft of the 1920s. It was a two-seat biplane with wings of equal span and a steel frame construction with fabric covering. The Boarhound was built as a private venture under Air Ministry Specification 8/24 (later superseded by Specification 20/25) for an Army cooperation aircraft to replace the Bristol Fighter , first flying on 8 June 1925 as
10-578: The Type 93 Boarhound . The Boarhound, designed by Captain Frank Barnwell , was a two-bay biplane which used a method of steel construction which involved high-tensile steel strips rolled into cusped and flanged sections, which were riveted together to form longerons and struts. The resulting structure was lighter, stronger, and cheaper than one made from drawn tubes. It had a deep fuselage allowing bulky radio and camera equipment to be carried, and
15-1362: The Type 93B Boarhound II . The only two Boarhound II s ever built were sold to Mexico in 1928 and were used against rebel forces in April 1929. The Boarhounds proved successful in Mexican service, their metal structure proving suitable for the climate. Two legends of the Mexican Air Force flew the Boarhound II: Pablo Sidar and Alfonso Cruz Rivera. Data from Bristol Aircraft Since 1910 General characteristics Performance Armament Aircraft of comparable role, configuration, and era Liaison aircraft The concept developed before World War II and included also battlefield reconnaissance , air ambulance , column control, light cargo delivery and similar duties. Able to operate from small, unimproved fields under primitive conditions, with STOL capabilities, most liaison aircraft were developed from, or were later used as general aviation aircraft. Both fixed-wing aircraft and helicopters can perform liaison duties. ( Fuerza Aérea Argentina ) Nazi period: Imperial period: Postwar period: This aviation -related article
20-696: The aircraft as a private venture for a general-purpose bomber to replace the Airco DH.9A . A second aircraft was therefore built, the Type 93A Beaver , which flew on 23 February 1927. This was rejected in favour of the Fairey III F, which used the preferred Napier Lion engine, of which large numbers were in store. The Boarhound I (registered G-EBLG) and the Beaver (registered G-EBQF) were withdrawn from use at Filton Aerodrome in April 1927. A further two aircraft were produced as reconnaissance fighters as
25-544: Was powered by a Bristol Jupiter IV engine with variable timing . The Boarhound was evaluated alongside the Armstrong Whitworth Atlas , de Havilland Hyena and Vickers Vespa . The Jupiter's variable timing gear gave poorer power at low altitudes, a disadvantage for an army cooperation aircraft, and the Atlas was considered superior. The Directors of Bristol decided, however, to continue development of
