Airspeed AS.5 Courier

 

1st Flight 1933

The Airspeed Courier was a wooden low-wing cantilever cabin monoplane.

Multiple power plants were also offered, while the Armstrong Siddeley Lynx engine was promoted for domestic use, the Armstrong Siddeley Cheetah radial engine was also used upon most Couriers.

Owing to its advanced aerodynamics, two Couriers were used as research aircraft, one by the Royal Aircraft Establishment (RAE) and one by Napier’s, who used it for development of the Napier Rapier engine.

The RAE aircraft was modified by Airspeed via the addition of high-lift devices and drag inducers, along with modified controls, for testing purposes.

At the outbreak of the Second World War, the majority of the surviving Couriers were impressed into the Royal Air Force (RAF), where they were typically used for communications purposes.

Only a single Courier survived the conflict, and was briefly used for joyriding flights at ‘Southend on Sea’ prior to being scrapped during December 1947.
