The Stinson Reliant is a popular single-engine four- to five-seat high-wing monoplane manufactured by the Stinson Aircraft Division of the Aviation Manufacturing Corporation of Wayne, Michigan.
The Reliant is a high-wing, fixed-tailwheel land monoplane powered with a variety of radial engines.[1]
1,327 Reliants of all types were made from 1933 to 1941, in different models, from SR-1 to SR-10. The final commercial model, the Stinson Reliant SR-10, was introduced in 1938. A militarized version was first flown in February 1942 and remained in production through several additional versions (all externally identical) until late 1943 for the US and British armed forces.[citation needed]
Reliant production can be broken into two distinct types – the straight-wing Reliants (all models up to SR-6) and the gull-wing Reliants (all models from SR-7 and after, including the militarized V-77/AT-19), with there being little in common between the two groups of types. The straight-wing Reliant has a wing of constant chord and thickness which is supported by two struts each side with additional bracing struts. In contrast the taper-wing Reliant has the broadest chord and thickness of the wing at mid-span, with the outer wing trailing edge heavily angled forward and a rounded cutout on the leading edge root, all supported by a single strut. The taper wing has a significant step up between the fuselage and the wing, and the changes in wing thickness gave it a distinct gull appearance from the front.[citation needed]
Operational historyedit
A Stinson (Vultee) V-77
The Reliant was used by the United States Army Air Forces in World War II as a utility aircraft, designated UC-81, and as trainer designated AT-19. The Royal Navy and Royal Air Force also used Reliants, for light transport and communication duties. After the war they were sold on the civilian market as the Vultee V-77.
The V-77 is a spartan version of the SR-10 with the 300 hp Lycoming R680-E3B, a single door on the left side and the traditional "bump" cowl was replaced with a simpler smooth cowl. Internal structure was beefed up significantly over the commercial models, and a distinctive triangle-shaped counterbalance was added to the rudder.[citation needed]
Two SR.5As impressed into service with the USAAF during World War II.[14]
L-12A
Two SR.7Bs impressed into service during World War II.[14]
RQ-1
One SR-5 Reliant was acquired by the US Coast Guard in 1935, later redesignated XR3Q-1 and decommissioned in 1941.[15]
XR3Q-1
One SR-5 Reliant was acquired by the US Navy in 1935.[16]
Reliant I
500 Reliants were supplied to the Royal Navy under Lend-Lease. The Reliants were used for light transport and communications, navigation and radio training duties.
Aeronaves de México – the Reliant was the first aircraft used by Aeronaves, later to become Mexico's largest airline, Aeromexico, on their initial service between Mexico and Acapulco on 14 September 1934[21]
