A hard-faced block used as a surface on which parts may be hammered or shaped.
Industry:Aviation
A hard-hitting air hammer, used to drive large, solid aluminum alloy rivets. A one-shot rivet gun hits the rivet with a single hard blow each time the trigger is pulled. This is different from the action of an ordinary rivet gun, which delivers a continuous series of blows as long as the trigger is held down.
Aluminum alloy rivets are strain hardened by repeated hammering, and they can become so brittle they crack. To prevent this, they can be driven with a single hard blow from a one-shot rivet gun.
Industry:Aviation
A headless screw used to prevent relative movement between a wheel and a shaft. A hole is drilled through the hub boss of the wheel, and it is tapped so a setscrew can be screwed through it and tightened against the shaft. The set screw prevents the wheel turning on the shaft.
Industry:Aviation
A heat exchanger that uses a flow of ambient air to remove heat from engine lubricating oil.
Industry:Aviation
A heat exchanger used on turbine engines to take heat from the engine oil and put it into the fuel. The fuel flows through tubes that pass through the hot engine oil. Heat from the oil enters the fuel and raises its temperature, and at the same time, the temperature of the oil is lowered.
Industry:Aviation
A heavier-than-air aircraft whose aerodynamic lift is produced by a set of rotating airfoils called rotors. Helicopters and autogiros are types of rotorcraft.
Industry:Aviation
A heavier-than-air flying machine that is supported in the air by aerodynamic lift produced by an engine-driven rotor. Since the rotor is engine driven, a helicopter does not need forward motion through the air for the rotor to produce lift.
Industry:Aviation
A heavier-than-air rotor-wing aircraft that is sustained in the air by rotors turned by aerodynamic forces rather than by engine power.
When the name Autogiro is spelled with a capital A, it refers to a specific series of machines built by Juan de la Cierva or his followers.
Industry:Aviation
A heavy canvas or leather bag filled with sand. A sandbag is used to shape sheet metal parts by forming a depression in the sand and hammering the metal into it with a soft-face mallet.
Industry:Aviation
A heavy contaminant that forms in an aircraft engine lubricating oil because of oxidation and chemical decomposition of the oil.
