Airscrew

The working range of the fuel screw on a four-stroke engine is one to three half-turns out, while the airscrew on a two-stroke engine has a working range of one-and-a-quarter to two half-turns out. ❋ Unknown (2007)

This was the variable-pitch airscrew, which made take-off and landing safer and increased the aircraft's maneuverability and climb during com - bat. ❋ Gallico, Paul (1959)

Verkan Vall read of a Fourth Level aviator, in his little airscrew-drive craft, sighting nine high-flying saucerlike objects. ❋ H. Beam Piper (1934)

On the other hand, the single-seater tractors were potentially the superior fighters, and in order to protect the blades of the airscrew the French were the first to use deflector blades on them in tractor machines. ❋ Frederick Hugh Sykes (1915)

Our early single-seater tractors were fitted with a Lewis gun fixed so as to fire over or at the side of the airscrew and actuated by a bowden wire, the most efficient, though not the most numerous, fighting machines at the end of 1915 being the Bristol Scouts. ❋ Frederick Hugh Sykes (1915)

The machine gun soon followed, but its use in tractor machines was impracticable on account of the danger of hitting the airscrew. ❋ Frederick Hugh Sykes (1915)

A bird is simpler than an aeroplane in that its wings both support it and drive it forward, whereas all aerial machines, both those that are heavier than air and those that are lighter than air, are at present driven forward by the thrust of an airscrew, revolving at the rate of some twenty to thirty times a second. ❋ Walter Alexander Raleigh (1891)

A later difficulty caused by the forward position of the airscrew had nothing to do with flying. ❋ Walter Alexander Raleigh (1891)

The wings were set at a dihedral angle, that is, they were bent upwards at the tips; and fore-and-aft stability was secured by a smaller pair of wings just in front of the airscrew. ❋ Walter Alexander Raleigh (1891)

Great Britain, maintained that the greatest hindrances to the solution of the problem of mechanical flight have always been the balloon and the airscrew. ❋ Walter Alexander Raleigh (1891)

An engine of four horse-power, weighing forty pounds, with a wooden airscrew five feet in diameter, was, by his calculations, amply sufficient to maintain his glider in horizontal flight. ❋ Walter Alexander Raleigh (1891)

A good illustration of this may be found in the question of the airscrew. ❋ Walter Alexander Raleigh (1891)

The other ship was designed by Baron Bradsky, secretary to the German Embassy in Paris; its total weight was made exactly equivalent to the weight of the air that it displaced, and it was to be raised by the operation of an airscrew rotating horizontally under the car. ❋ Walter Alexander Raleigh (1891)

The monoplane, from the first, was a 'tractor' machine; its airscrew was in front of the planes, and its body, or fuselage, was covered in and streamlined, so as to offer the least possible resistance to the air. ❋ Walter Alexander Raleigh (1891)

It took the air near Berlin on the 3rd of November 1897, but something went wrong with the airscrew belts, and it was seriously damaged in its hasty descent. ❋ Walter Alexander Raleigh (1891)

The first of these objections was not fully met until firing through the airscrew was introduced; the second was for ❋ Walter Alexander Raleigh (1891)

The motive power was supplied by twisted strands of rubber which, as they untwisted, turned the airscrew. ❋ Walter Alexander Raleigh (1891)

Fokkers late in 1915 had been fitted with guns which fired through the airscrew. ❋ Walter Alexander Raleigh (1891)

This ship, with an airscrew driven by manpower, attained a speed of five and a half miles an hour. ❋ Walter Alexander Raleigh (1891)
