subsonic flight

However the delta wing is less efficient for subsonic flight.

Even in subsonic flight, their engines set off car alarms and shook houses on the ground.

Aircraft flying at airspeeds lower than the speed of sound in air is subsonic flight.

The plane was just decelerating into subsonic flight.

Success, some experts say, could make supersonic travel as cheap as subsonic flight by the year 2000.

Early jet aircraft used turbojet engines which were relatively inefficient for subsonic flight.

At the moment it passes from supersonic to subsonic flight, two quick booms will announce the shuttle's approach.

The passengers were transferred to subsonic flights.

The information regarding unfavourable transonic/subsonic flight behaviour for some of the tested projectiles is important.

In subsonic flight, the plane pushes the air ahead of it out of the way as it moves.

And much of this increase will occur on long-haul routes with grueling subsonic flight times of 9 to 16 hours.

This shape is popular in subsonic flight (such as model rocketry) due to the blunt nose and tangent base.

The suit provides the user with the ability of subsonic flight, thanks to magnetically powered turbine boot jets.

At subsonic flight speeds, the conical inlet operates much like pitot intake, it sucks air.

For a ramjet operating at a subsonic flight Mach number, exhaust flow is accelerated through a converging nozzle.

There was a clap of thunder overhead, the sonic boom of the Feynman as it slowed to subsonic flight.

Recovering from the dive and the resumption of severe buffeting once subsonic flight was resumed would have been very likely to damage the craft terminally.

We now know that the air resistance of the spherical cannon ball in supersonic flight is much much greater than in subsonic flight.

This implies some (mostly smaller calibre) rifle bullets exhibited coning and/or tumbling in the transonic/subsonic flight velocity regime.

For symmetric airfoils in subsonic flight the aerodynamic center is located approximately 25% of the chord from the leading edge of the airfoil.

Without the Concorde, to be sure, some of these travelers would shift to subsonic flights offered by British Airways or Air France.

Yesterday's 50-minute subsonic flight, with only an Air France crew on board, was to a military base at Istres, near Marseilles, for 15 days of tests.

Subsonic flight airfoils have a characteristic shape with a rounded leading edge, followed by a sharp trailing edge, often with asymmetric camber.

At the front of each inlet was a pointed, movable cone called a "spike" that was locked in its full forward position on the ground and during subsonic flight.

The location of the center of pressure depends on the flow field structure, in other words, depending on whether the bullet is in supersonic, transonic or subsonic flight.
