The air load change takes place in the two-stroke section of the engine.

Similarly, the spine would distort under air loads, hence the rather short spines of earlier designs.

The piston of the four-stroke section is an air load exchange aiding system, working as a system of valves.

The two-stroke combustion engine is characterized by a simple construction and system of air load change as well as bigger index of power output.

Those tend to be the most troublesome during launching and include the protuberance air load ramp, the section where debris fell during the Discovery liftoff.

Aircraft fitted with variable-pitch propellers or constant speed propellers are started in fine pitch to reduce air loads and current in the starter motor circuit.

Further, an active aeroelastic wing can be used to reduce induced drag at low wing strain conditions and, at higher strain conditions, reduce maneuver air loads.

In addition, Protuberance Air Load (PAL) ramp foam had also shed pieces, and there were also spot losses from large-area foams.

At one point in my career, I worked in Langley's Full-Scale Tunnel, which was used to test full-size aircraft mounted to a system that measured air loads on airplanes.

The possibility that a large chunk of insulating foam might break away from a section of the tank called the protuberance air load ramp - PAL for short - never came up.

Pulling up a little I check, relinquish the throttles and, using both hands, force the stick left against the air loads to again watch earth and sky revolve effortlessly as we describe the easiest-ever aileron roll.

Attention has focused on the manufacture of the tank and on the area where the largest piece of foam fell off, a long aerodynamic feature known as the protuberance air load ramp, or PAL ramp.

The lower boom in the main spar had failed at the outboard edge of the engine nacelle and then the upper boom had also failed as the result of the wing folding upwards under the air loads imposed on it.

However, the engine separation had severed the hydraulic fluid lines that controlled the leading edge slats on the left wing, causing the slats outboard (towards the tip of the wing) of the separated engine to retract under air load.

At 127.1 seconds after liftoff, and 5.3 seconds after SRB separation, a large piece of debris separated from the Protuberance Air Load (PAL) ramp, which is part of the external tank (see animation, above left).

It is known as the protuberance air load ramp, which NASA abbreviates as the PAL ramp, and was designed to minimize crosswise airflow and turbulence around cable trays and lines used to pressurize the external tank.

Here he was involved in the development of zeppelins and was able to assemble a body of research around wind-tunnel experiments on air loads and moments acting on airships in curved flight and when moored, which formed the basis of his doctorate thesis.

This radical wing configuration was designed to maintain a constant angle of incidence regardless of flexing, by placing the torsion box well back in the wing so that the air loads, acting in the region of the quarter-chord line, have a considerable moment arm about it.

By using multiple leading and trailing edge controls like "aerodynamic tabs", subtle amounts of aeroelastic twist can be controlled to provide large amounts of wing control power, while minimizing maneuver air loads at high wing strain conditions or aerodynamic drag at low wing strain conditions.

The air load change takes place in the two-stroke section of the engine.

Following megger tests to record clean plate air load characteristic.

Do not include the outdoor air load, as the primary air handler will cope with this.

Similarly, the spine would distort under air loads, hence the rather short spines of earlier designs.

Air loads on the wing resulted in an uncommanded retraction of the outboard slats.

Air loads then blew up through the vertical tail and dislodged the horizontal stabilizer and elevators.

The piston of the four-stroke section is an air load exchange aiding system, working as a system of valves.

The two-stroke combustion engine is characterized by a simple construction and system of air load change as well as bigger index of power output.

Those tend to be the most troublesome during launching and include the protuberance air load ramp, the section where debris fell during the Discovery liftoff.

The initial explosion blew from the pressurized baggage compartment into the unpressurized fuselage behind, and air loads began tearing parts from the plane.

During takeoff a hinged cover on the aircraft's pitot probe, designed to deflect under air loads, did not operate correctly, giving erroneous airspeed indications.

The upper portion of the fin is a distributed flange where substantial covers take spanwise loads due to bending as well as air loads.

Aircraft fitted with variable-pitch propellers or constant speed propellers are started in fine pitch to reduce air loads and current in the starter motor circuit.

"If you see a large fuel tanker coming towards you, get out of the way and run," says an RAAF Air Load Team officer.

Work on cone profiling, pioneered by JORDAN, has refined this behaviour to achieve an extremely close match between the cone and air load characteristics.

Further, an active aeroelastic wing can be used to reduce induced drag at low wing strain conditions and, at higher strain conditions, reduce maneuver air loads.

In addition, Protuberance Air Load (PAL) ramp foam had also shed pieces, and there were also spot losses from large-area foams.

In some new buildings with large fresh air loads, such as hospitals, factories and supermarkets, chemical desiccant systems dehumidify incoming fresh air to cut the loads on chillers.

The possibility that a large chunk of insulating foam might break away from a section of the tank called the protuberance air load ramp - PAL for short - never came up.

This has resulted in the manufacture of improved piezoelectric composite transmitters and receivers in terms of surface displacement, reception sensitivity and insertion loss when operating into an air load.

Also in 2007, the RAAF's No. 1 Air Operations Support Squadron was expanded by 80 personnel to provide air load teams to support the Globemasters.

Pulling up a little I check, relinquish the throttles and, using both hands, force the stick left against the air loads to again watch earth and sky revolve effortlessly as we describe the easiest-ever aileron roll.

Working with the air load team at the vast and eternally dusty Kandahar airfield is a tough job for anyone but nothing seems to phase 25 year old Leading Aircraftsman Kylie Barnes from Canberra.

Attention has focused on the manufacture of the tank and on the area where the largest piece of foam fell off, a long aerodynamic feature known as the protuberance air load ramp, or PAL ramp.

If air load elements are used, mount the elements in a suitable position or on a frame and connect each load element to the corresponding numbered phase and neutral DIN connector inside Powerflow.

After refusing aid from other countries, Turkey has relented, even accepting an airload of prefabricated houses from Israel, its estranged former ally.

More than five million of those simulations looked specifically at debris from the liquid hydrogen protuberance airload ramp, better known around NASA by the acronym LH2 PAL ramp.
