      The advantages associated to Vertical Short-Take-Off and Landing (V/STOL) have been demonstrated since the early days of aviation, with the initial technolology being based on airships and later on helicopters and planes. Its operational advantages are enormous, being it in the field of military, humanitarian and rescue operations, or even in general by: The EU supported research project, abbreviated as GABRIEL, investigated whether magnetic levitation assisted take-off and landing is feasible, cost effective and objective of this paper is to show the developed operational concept, its key characteristics, the required improvements in aircraft and aircraft operation, the validation results and the impact by: 5.

Nozzle Concepts The four nozzle concepts tested were (1) an axi-symmetric nozzle, (2) an asymmetric, load-balanced exhaust nozzle, (3) a lwo aspect ratio, single expan-sion ramp nozzle, and (4) a high aspect ratio, sin-gle expansion ramp nozzle.

Each nozzle concept was tested with an area ratio A t =A e appropriate for dry pwoer and afterburning pwoer. Four advanced nozzle concepts were tested on a canard-wing fighter in the Langley by Foot Subsonic Tunnel.

The four vectoring-nozzle concepts were (1) an axisymmetric nozzle (AXI), (2) an asymmetric, load-balanced exhaust nozzle (ALBEN), (3) a low aspect ratio, single expansion ramp nozzle (LASERN), and (4) a high aspect ratio, single expansion ramp nozzle (HASERN).

[P Frank Quinto; Guy T Kemmerly; John W Paulson; United States. National Aeronautics and Space Administration. Scientific and Technical Information Program.]. Four advanced nozzle concepts were tested on a canard-wing fighter in the Langley by Foot Subsonic Tunnel. The four vectoring-nozzle concepts were as follows: (1) an axisymmetric nozzle (AXI); (2) an asymmetric, load balanced exhaust nozzle (ALBEN); (3) a low aspect ratio, single expansion ramp nozzle (LASERN); and (4) a high aspect ratio, single expansion ramp nozzle.

ICAS CONGRESS Abstract. The development of the baseline configuration, the design synthesis and the optimization of the baseline configuration of an advanced short take-off and vertical landing (ASTOVL) combat aircraft are presented.

The evaluated baseline configuration is an advanced technology, supersonic STOVL combat aircraft design with an internal weapon bay and powered by a military turbofan with a remote lift system (RLS) for landing.

Sunol and Vucinic [] have started a preliminary analysis of integration of the ACHEON nozzle into an aerial ng upon this preliminary result, this paper aims to analyze how the ACHEON nozzle can be further integrated into aircraft architecture, and in particular will focus on the definition of a specific aircraft model taking maximum advantage of this by: 6.

The pilot informed us this was due to a light that came on during takeoff that indicated high pressure/temperature. Here is the full trip report showing what.

Aircraft propulsion 2. Taking advantage of moving within a fluid, aircraft propulsion is achieved by air-breathing engines, i.e. engines that take a stream of air and throw it at higher speed backwards.

The project eventually became a combined US and UK study called ASTOVL, for Advanced Short Take-Off/Vertical Landing. The simplest technique explored by ASTOVL was the addition of plenum chamber burning to each of the Harrier's four rotating nozzles.

This led to the first VTOL engines as used in the first British VTOL aircraft, the Short SC.1 (), Short Brothers and Harland, Belfast which used four vertical lift engines with a horizontal one for forward thrust. The Short SC.1 a VTOL delta aircraft. The Short SC.1 was the first British fixed-wing VTOL aircraft.

Bythe Air Force and the U.S. Army were looking at a mix of at least two new vertical- and short-takeoff and landing capable aircraft programs, known as the Advanced Mobility Concept (AMC-X. The British Aerospace Sea Harrier is a naval short take-off and vertical landing/vertical take-off and landing jet fighter, reconnaissance and attack aircraft; the second member of the Harrier Jump Jet family developed.

Special drag prediction problems peculiar to short take-off and landing (STOL) designs, such as jet flap thrust recovery, and energy efficient aircraft concepts, for example laminar flow control, are beyond the scope of this chapter; as are drag due to speed brakes and fighter aircraftCited by: 4.

A rotating cascade of vanes is used in each nozzle to vector the thrust from a horizontal direction for high-speed flight to a vertical direction for hovering and vertical takeoff and landing.
