Bristol Type 148

The Bristol Type 148 was a two seat, single engine low wing monoplane built in 1937 to an Air Ministry specification, A.39/34, for an army cooperation aircraft meant to replace the Hawker Audax and Hector. Following the layout of the Types 133 and 146, it had stressed skin wings of constant chord, an all monocoque fuselage, split flaps and connected wingtip slots for handling at low speed, and a pilot and observer in tandem cockpits under a continuous canopy. The intended engine was the Bristol Perseus, but it made its first flight on 15 October 1937 with a Mercury IX. It lost the competition to the Westland Lysander and did not progress past the two prototypes built.
