Deck Torpedo Bomber

Vought/Consolidated

TBU-1

TBU-1 Vought. Structurally, in comparison with the TBF-1 torpedo bomber that was being developed at the same time, the Vough torpedo bomber had a longer fuselage, a different shape tail, as well as the landing gear retraction scheme. The landing gear was retracted into the wing backward in flight with a turn of 90 °. A slight advantage was also the slightly stronger offensive armament, which consisted of three 12.7mm Browning machine guns versus the Avenger's two. During the construction of the aircraft, one interesting innovation was used, which was an automatic system that synchronously controls the release and retraction of the landing gear, flaps and the pitch of the propeller.

The first flight of the TBU-1 prototype took place on December 22, 1941.

To improve the flight performance of the aircraft, the Pratt & Whitney XR-2800-6 (1800 hp) engine was replaced with an R-2800-2 with 2000 hp. with a Hamilton-Standart propeller with a diameter of 4.06 m. After all possible modifications, the performance characteristics of the torpedo bomber rose quite insignificantly and, in fact, it was equivalent to the TBF-1.

TBY-2 Consolidated. In September 1943, the order for production was transferred to Consolidated, due to the fact that Vought was extremely busy with the production of F4U Corsair fighters and OS2U Kingfisher float reconnaissance aircraft. The aircraft's designation changed to TBY-1, but Consolidated began to produce the next modification, TBY-2, which also received its own name Sea Wolf. It differed from TBU-1 in a more powerful R-2800-22 engine (2100 hp) and in the presence of a locator antenna in the fairing of the right wing console.

Armament. Three forward-firing 12.7 mm Browning machine guns, one 12.7 mm machine gun in the dorsal turret and one 7.62 mm machine gun in the ventral position; bomb load - up to 726 kg or one 907 kg torpedo.
