lift jet

The second aircraft was converted to lift jets instead, also crashing after several tests.

This aircraft featured eight small vertical lift jets straddling the main engine.

The city and the sunburned coast dropped below as the lifting jets carried them effortlessly up into the sky.

Despite the skirling wind, the scars from its lift jets remained as pits in the soil.

However, it became apparent very early that this configuration was unsatisfactory, as the lift jets became useless dead weight once airborne.

These include the rotary-winged helicopter and craft that use lift jets (e.g. the flying bedstead).

Lift jets were first designed by German engineers during World War II, but none saw operational service.

Some VTOL designs have used both vectored thrust from the main engine together with auxiliary lift jets.

In addition to the wingtip engines, two further lift jets were installed in the fuselage to supplement the main engines in hovering flight.

In the 1980s the British MoD and the US DoD both conducted studies into lift jet solutions.

The A-57 was equipped with a lift jet (similar to VTOL aircraft today) facing downward to assist its take-off from the surface of the ocean.

The engine would have had a large air bleed leading to an auxiliary combustion chamber located in the nose, though separate lift jet would have been retained.

A Lift jet is a lightweight jet engine used to provide vertical thrust for VTOL operation, and is then shut down in forward flight.

The two Pratt & Whitney JT12 engines were replaced with six General Electric J85 turbojets four of these units acting as lift jets.

A lift jet is an auxiliary jet engine used to provide lift for VTOL operation, but may be shut down for normal wing-borne flight.

From April 1991, various kinds of rolling take-off and run-on landings were performed on normal runways and also "ski-jump" ramps at the lift jet center at Saky.

The Soviets did side-by-side testing of versions of combat aircraft using variable geometry wings and lift jets (the results became the Mikoyan MiG-23 and Sukhoi Su-24).

The A.W.171 design was a very slender delta flying wing powered by two Bristol Orpheus turbojets mounted at the wingtips, with 10 Rolls-Royce RB.108 lift jets.

The transfer of approximately 1/3 of the power available for hot nozzle thrust to the lift fan reduces the temperature and velocity of the rear lift jet impinging on the ground.

A lift jet is a jet engine angled to provide an aircraft with aerostatic (i.e. not requiring the movement of air over an airfoil) lift instead of (or in addition to) thrust.

The British Hawker Siddeley Harrier used vectoring nozzles, while the Russian Yakovlev Yak-38 Forger attack jet used lift jets in conjunction with rotating rear nozzles.

A novel alternative to the lift jet for auxiliary vertical thrust is to be employed by the VTOL Lockheed F-35B version of the U.S. Joint Strike Fighter program.

Similar problems were then encountered when 'Minsk' sailed off the coast of West Africa and then in the Indian Ocean; in these instances the lift jets proved unwilling to start under hot and humid conditions.

On a fixed-wing aircraft, lift jets may be installed as auxiliary engines, with a separate engine to provide forward thrust, or, as in the Harrier jump jet, may be vectored in flight to provide both.
