As evidenced by hollow cavities in the wing bones of larger species and soft tissue preserved in at least one specimen, some pterosaurs extended their system of respiratory air sacs ( see Paleobiology section below ) into the wing membrane itself.

The airflow created by the fans that is entering the tunnel is itself highly turbulent due to the fan blade motion ( when the fan is blowing air into the test section – when it is sucking air out of the test section downstream, the fan-blade turbulence is not a factor ), and so is not directly useful for accurate measurements.

He was assigned to the Cavite Navy Yard in the Philippines, expecting to be transferred shortly to the Bureau of Engineering in Washington D. C.

S., Rickover arrived in Washington and took up his duties as assistant chief of the Electrical section of the Bureau of Engineering on 15 August 1939.

A thermal column ( or thermal ) is a vertical section of rising air in the lower altitudes of the Earth's atmosphere.

Outside, " fresh " air is generally drawn into the system by a vent into the indoor heat exchanger section, creating positive air pressure.

The load compressor is generally a shaft-mounted compressor that provides pneumatic power for the aircraft, though some APUs extract bleed air from the power section compressor.

The instrument section and the spinning tub were slowly tipped to a horizontal position by means of four air jets located at the base of the instrument section.

The justification for the additional expenditure and complexity related to digging a tunnel for part of the way – rather than simply raising that section of the bridge – was to avoid interfering with air traffic from the nearby Copenhagen International Airport, and also to provide a clear channel for ships in good weather or bad, and to prevent ice floes from blocking the strait.

Apparently in the post Civil War era some time before or around 1882, from the publishing date, a ship was purchased by a Captain CHARLES L DINGLEY called the Ericssan with a weight of 1, 645 tons that was built by John Ericssan ( Although the above section on John Ericssan's Friendship with Cornelius H.

The derivation includes the first two equations given in the Practical formula for dry air section above.

Shaped like a section of a large aerofoil ( this creates a low pressure area above the wing much like an aircraft ), the craft was propelled by four aero engines driving two submerged marine propellers, with a fifth engine that blew air under the front of the craft to increase the air pressure under it.

What actually happened is that the slight narrowing of the distance between the walls resulted in less airflow, which in turn led to more air loss under that section of the skirt.

Desson Howe, writing for The Washington Posts Weekend section, said that " the Klingons ' spilled blood floats in the air in eerily beautiful purplish globules ; it's space-age Sam Peckinpah.
