Brewster XA-32

 

1st Flight 1943

Initially designed in 1941, the XA-32 was grossly overweight, at almost 20,000 lb (9,100 kg), similar to the Douglas A-20 Havoc.

The drag induced by its bulbous shape was amplified by careless detail design, which left it festooned with bumps and lumps.

One disastrous characteristic was that the exhaust scoops that ringed the cowling nearly blinded the test pilots during night flying; the backfiring at low power settings resulted in flames engulfing the nose of the aircraft.

Even with the 2,100 hp (1,600 kW) Pratt & Whitney R-2800, the XA-32 was underpowered and an attempt to re-engine the aircraft with the 3,000 hp (2,200 kW) Pratt & Whitney R-4360 Wasp Major was unsuccessful.

The first flight of the XA-32 prototype was not until May 22, 1943, two years after the design was proposed, and almost every aspect of performance fell short of the specifications.

Without its load of weapons, the XA-32 could only reach 279 mph (242 kn; 449 km/h) and although handling was adequate, as soon as armament and external stores were added, the performance dropped drastically and more seriously, the disturbed airflow set up severe buffeting at its top speed.

Only two examples were built, the XA-32 and XA-32A, both of which were scrapped at the conclusion of flight testing.

The XA-32 failure was to be the last product and the end for Brewster.
