Graph showcases the McDonnell F3H-2 Demon’s operational range on internal fuel when compared to distances between major cities. But no other engine could simply be fitted into the old Demons, as both the wings and fuselage would have to be redesigned and enlarged. Although the Demon was the Navy’s first true all-weather missile fighter, and its’ front line all-weather interceptor from , until it was replaced by the F-4 Phantom in , it is remembered by very few. Later versions of the aircraft were designed for all-weather operations and could carry the AIM-7 Sparrow missile, yet the Demon never shook its troubled reputation. For the camera, see Nikon F3H. In this photo the Demon is carrying a Delmar target boom mounted on the outboard missile pylon and its air driven winch mounted on the inboard missle pylon.

The F3H Demon was originally designed around Navy’s ambitious new Westinghouse J40 which was to offer enough power to use just one engine in a number of new aircraft designs. Troubles with the Westinghouse J power plant immediately threatened the F3H program. But the engine would ultimately fail to produce the promised thrust or run reliably.

McDonnell F3H Demon – Wikipedia tiếng Việt

The first Demon with a J71 flew in October With the Department of Defense budget having been passed by Congress and signed by the President, the National Naval Aviation Museum is not affected by the government shutdown and will be open from 9: From Wikipedia, the free encyclopedia.

The wing mainplanes were low-mounted along the fuselage sides and featured rounded tips. The result was the XF3H-1 Demon, which first flew in Fighters of the Fifties. Inthe F3H was redesignated F Speed brakes were extended during landing approaches to minimize engine operation in the unstable power range during landing approaches. AeroplaneVolume 36, No. The dawn of the jet age also ushered in an all-new generation of fighter for the United States Navy USN and the McDonnell concern became a longtime contributor to the service branch with various designs introduced.


F3H Demon: The good, The Bad And The Ugly

Air EnthusiastForty-three,pp. Despite the problems, the Navy ordered F3H-2 s, and the first were deployed in March The engine of choice became the in-development Westinghouse J40 which promised over 10, pounds of thrust output from a single source. Reality Demon Page 3: Later versions of the aircraft were designed for all-weather operations and could carry the AIM-7 Sparrow missile, yet the Demon never shook its troubled reputation.

In case of hydraulic failure, a ram air hydraulic pump popped out from the belly of the aircraft, just forward of the the belly of the aircraft, just forward of the lower engine access bay, driving a hydraulic pump that powered the small emergency-only hydraulic demob.

McDonnell and McDonnell Douglas military aircraft and spacecraft. From this work arrived an all-new development, the first by McDonnell to feature swept-back wing mainplanes, in the subsonic F3H “Demon”.

A reconnaissance version, the F3H-2Pwas proposed, but never built. The engine was a major disappointment, producing only half of the expected power.

McDonnell Edmon Corporation Type: These seats were replaced by Martin Baker seats, with much improved reliability and performance Early production F3H ‘s had a tendency to flame-out when flying in rain or icing conditions. A single engine configuration was selected this time around while the aircraft was to be crewed by one.


Angelucci, Enzo and Peter M. The Demon was withdrawn before it could serve in Vietnam where the F-4 Phantom II, itself conceived as an advanced development of the Demon, was a mainstay. Of 35 F3H-1N aircraft flown with the J40 engine, eight were involved in major accidents.

It was an infamously troubled aircraft; engine problems plagued the first version of the airplane, resulting in eleven crashes and c3h deaths of four pilots between and As the Demon’s airframe was too small to fit any larger, more current and proven jet engine, the next batch of production fighters were delivered with the Allison J71 turbojet.

Due to excellent visibility from the cockpit, the Demon earned the nickname “The Chair”.

McDonnell F3H Demon

Nevertheless, the USN was in need of high-performance, frontline fighters and continued to push the F3H program along. With the exception of the A3 which did not require a bifurcated intake ductthe Westinghouse engine failures ruined an entire generation of Naval aircraft.

Standard, fixed armament comprised 4 x 20mm Colt Mk 12 cannons some versions removed a pair as a weight-saving measure.

The experimental version of the Demon. The J engine, which promised 10, to 11, lbs.
