Add to basketSigned by author on the front endpage, no dust jacket, as issued? Black cloth boards are soiled, binding sound, internally clean. 'Thrusting Forward' is an informal history of the aircraft propeller. It is also a tribute to the men and women who have contributed in large and small measure to the propeller's proud past and its promising future.The aircraft propeller - with the clean, graceful lines of its blades and smooth, sculpted roundness of its spinner mechanism - looks like a simple mechanism. The simplicity in appearance, however, is deceiving for the propeller embodies the highest sophistication in aerodynamics, mechanical engineering and structural design.Essentially a wing, the rotating propeller converts its 'lift' into thrust. The propeller's rotation and the angel at which the blade strike the air control aircraft speed in all phases of flight while the engine's speed remains constant and the aircraft's speed and altitude vary. Varying, too, across the blade from hub to tip are the direction and velocity of the air flowing through the propeller. In addition, environment and other stressors have also be taken into consideration in its design and development.
