Huff-Daland LB-1 Pegasus

The little-known Huff-Daland factory in Ogdenburg, New York, was the designer of the first LB (light bomber) category bomber, designed by C. The XLB-1 prototype was single-engine only, the chosen engine being the powerful 597kW Packard 1A-2540 inline engine. It was a large biplane, with a canvas-covered steel tube structure. The tail surfaces were simple. The crew was a three-man crew, with the pilot and copilot seated side by side behind the engine and the gunner positioned in the middle of the back of the fuselage. The aircraft had a bomb bay where all the bombs were placed, targeting was done through a window in the cockpit floor. The undercarriage with oil-pneumatic shock absorbers was also modern for its time.

The XLB-1 was first shown to the public at the National Air Races held at Mitchel Field on Long Island. The XLB-1 competed in the transport aircraft category, which it won. Based on the prototype, nine machines were ordered for military trials in 1925 (the tenth ordered was later cancelled). Completed in July 1927 (by which time the company was already based in Bristol), they differed from the prototype in having a Packard 2A-2540 engine with the radiator moved under the engine, a fourth crew member to operate a movable machine gun in the fuselage floor, and nearly double the bomb load - 1,247 kg compared to the 680 kg of the prototype. This additional weight affected performance, especially range. The company named its creation Pegasus, but this name was not accepted by the military.

By the time the production machines were taken over, however, the USAAC had already decided to prefer the twin-engine concept, which after all had the advantages of greater safety in the event of a single engine failure, and allowed the gunner/gunner to be placed in the nose. Test experience with the LB-1 confirmed this, and it was therefore the last USAAC single-engine bomber. However, they became the basis for further development, both in the line of subsequent, already twin-engined LBs, and in the enlarged form of the heavy bomber HB-1.
