2021年9月26日 · The T49 turboprop was applied to the experimental Boeing XB-47D version of the Stratojet bomber. Curtiss-Wright bought the B-17 from the Air Force and flew tests, including a turbo-compound version of the R-3350 piston engine. Pratt and Whitney used its test bed B-17 for the T34 turboprop engine.

The Boeing B-17 Flying Fortress is an American four-engined heavy bomber aircraft developed in the 1930s for the United States Army Air Corps (USAAC). A fast and high-flying bomber, the B-17 was used primarily in the European Theater of Operations and dropped more bombs than any other aircraft during World War II .

4x Wright Cyclone GR-1820-97 nine cylinder radial engines with General Electric B-22 waste gas turbochargers with 1,200 hp start performance and 1,380 hp emergency-combat-management in 26,700 feet of altitude. Cylinder drilling: 155.6 mm; Piston stroke: 174 mm; 29.88 liters. 13 x .50 calibre machine guns. Maximum bomb load: 7983 kg.

Each engine on the B-17 has a turbo-supercharger which boosts manifold pressure for takeoff and provides sea-level air pressure at high altitudes. To operate the turbo-superchargers, engine exhaust gas passes through the collector ring and tailstack to the nozzle box, expands to atmosphere through the turbine nozzle, and drives the bucket wheel ...

Airplane equipped with four (4) Wright R-1820-65 engines with torque meters; exhaust driven turbo superchargers; 3-bladed constant speed propellers, blade design No. 6153A-18, blade angle range 21° - 88° at 42" radius. Landing gear retracted, wing flaps neutral, inter-cooler shutters wide open unless otherwise specified.

2024年7月17日 · Beginning with the B-17A, it was the first Air Corps bomber to employ the turbosupercharger to significantly improved its higher altitude performance. This post will explore some of the details of the engines and superchargers that powered the airplane, and address some of their misconceptions. What is a Supercharger? First, to define some terms.

Boeing B-17 Flying Fortress Power Plant: Number of engines: 4: Engine details: 4x Wright R-1820-97 radial engines: Horsepower (HP): 4x 1200 hp

The Boeing B-17 Flying Fortress four-engine heavy bomber is one of the most famous and successful airplanes ever built. The B-17 received the name “Flying Fortress” from a Seattle news reporter who commented on its defensive firepower, and said “It’s a Flying Fortress”.

2024年8月2日 · The B-17's strategic importance was highlighted by its ability to fly at high altitudes of 25,000 to 35,000 feet (7,500 to 10,500 meters), thanks to its powerful engines. This allowed pilots to evade enemy defenses while delivering precise and powerful strikes, with the Norden bombsight providing high levels of accuracy when offloading bombs.
