The B-17 Flying Fortress was powered by four Wright R-1820-39 turbo super-charged Cyclone Radial Engines, delivering over 1200hp, giving the mainstay of the USAAF’s bomber fleet a top speed of 287mph with a range of over 2,000 miles.
For its pilots and crew, the B-17 was an extremely stable and robust aircraft capable of sustaining considerable damage and still bringing its crew home safely.
Unlike the British heavy bombers, the B-17 featured two pilot positions, with the co-pilot seated to the right of the cockpit, able to relieve the chief pilot during the often lengthy flights or take control of the aircraft if the pilot was killed or injured.
The co-pilot would be responsible for monitoring the aircraft's systems in particular, the B-17's powerful Wright supercharged engines with key engine gauges such as Fuel, Cylinder Head Temperature and Engine RMP's located to the right of the main flying panel directly in front of the co-pilot.
The B-17's two RPM gauges sat side by side, just below the Manifold Pressure gauges with the left hand gauge monitoring the Port No 1 & 2 engines and the right, the Starboard No 3 & 4 engines.
Early USAAF RMP gauges were mainly mechanical tachometers mounted to the instrument panel with a direct flexible drive cable to the engine's tachometer drive. Later models, such as gauge featured here, were electrical remote indicators connected electrically to a generator or autosyn transmitter attached to the engine’s tachometer drive.
Produced by the Chicago Flexible Shaft Co, this AN5530 - 2A Electric Tachometer monitored the starboard 3 and 4 engines of the B-17 and is dated 1945 with additional service stamps on the rear of the unit. The face glass is relatively unmarked and the unit is in remarkable condition for a gauge over 75 years old.
Mounted in its 100yr old mango Wood Display Stand with engraved plaque, printed and laminated Fact Sheet and an incredible detailed 1/72 scale model of the B-17 perched atop its removable magnetic arm, this Recovery Curios WWII B-17 flight instrument display would make a fantastic gift for any aviation enthusiast.
This B-17 Flying Fortress Instrument comes complete with detailed Scale Model, Mango Wood Stand & Plaque plus Printed Fact Sheet featuring photo of instrument in aircraft cockpit.
