Rotary-Wing Examples - ANSWER Helicopters, gyro-copters, and tilt-rotor flying
machines
Aircraft - ANSWER Machine supported aloft by lift created by air flowing across airfoil,
wings, propeller, rotor blades or buoyancy
Civilian Aircraft categorized as - ANSWER normal, utility, acrobatic, commuter,
transport, manned free balloons, special classes
Military aircraft are categorized based upon - TYPE of the mission that they fly
Flaps - MOVEABLE extend wings surface area and increase (strengthen) lift in order to
decrease air speed
Spoiler - MOVEABLE Hinged panels that rise after touchdown to eliminate lift
Air Brakes (Speed Brakes) - MOVEABLE Slow the aircraft during flight and steepen the
rate of descent
Spar - MOVABLE The primary structural member within each wing
These run lengthwise along the wing
, Ribs - ANSWER are attached perpendicularly to the spar to provide more support and
strength
Wings of most planes that fly below the speed of sound - ANSWER Are shaped
perpendicular
Wings of most planes that fly above the speed of sound - ANSWER are swept back to
delay the drag of air compressibility. Swept wings increase the performance on high
performance planes
Delta wing This is a triangular shaped wing
Variable Geometry wings The wings are positioned perpendicular at take off, landing
and low air speeds, then move to a swept position when flying at high speeds
Planes that take off and land on water have Floats. They will take off and land on both
water and land because they have retractable wheels
4 major aerodynamic forces that act on an aircraft while it is in flight - ANSWER weight
lift
thrust
drag
Total weight force acts through the - ANSWER Center of gravity
Lift - ANSWER The force that opposes the weight and lifts the machine upwards
Produced by air foils
Thrust - ANSWER Aircraft's forward force. This is provided by its engines
