Billy Mitchell Aerospace Test Latest Update Already Graded A Aerospace Education Branch of general education concerned with communicating knowledge, skills and attitudes about aerospace activities and the total impact of air and space vehicles upon society Airport Place on either land or water where aircraft can land and take off for flight AGL Above Ground Level Aerospace A combination of aeronautics and space Aviation The art, science and technology of flight within the atmosphere Aviatior Person who operates an aircraft during flight Supersonic Faster than the speed of sound Subsonic Slower than the speed of sound Aero Pertaining to air Airplane An aircraft that is kept aloft by the aerodynamic forces upon its wings and is thrust forward by a propeller or other means of propulsion Static Standing still/ non-moving Airfoil A component, such as a wing, that is specifically designed to produce lift, thrust, or directional stability Airfoil Components Leading edge, trailing edge, chord, camber Aircraft Any machine capable of flying through the air Air 79% Nitrogen, 19% Oxygen, 2% other Aerodynamics Relating to the force of air in motion Aeronautics The science of flight within the atmospehere Mongolfier Brothers French brothers who created the first manned hot air balloon in 1783 Dynamic Lift Newton's Lift, takes effect when a bird changes its body angle slightly upward to it's flight path Induced Lift Bernoullian Lift, pressure difference between upper and lower areas of a bird's wing Dynamic Force in motion Daniel Bernoulli Discoverer of relationship between pressure and fluids in motion Bernoulli's Principle When a fluid accelerates, the pressure drops Newton's 1st Law An object at rest remains at rest unless acted upon by an outside force Newton's 2nd Law A force acting upon a body causes it to accelerate in the direction of the force; acceleration is directly proportional to the mass of the body being accelerated Newton's 3rd Law For every action, there is an equal and opposite reaction Trailing Edge The back portion of an airfoil Coefficient of Lift Formula Mathematical formula with 5 components: air density, velocity, wing area, airfoil design, angle of attack Camber Curved part of the airfoil that goes from the leading edge to the trailing edge Leading Edge The front portion of an airfoil Relative Wind The flow of air which moves opposite the flight path of an airplane Natural Forces of Flight Drag and Gravity Forces of Flight Lift, Thrust, Weight (Gravity), Drag Thrust Moves an aircraft forward Drag Force that retards forward movement of the aircraft Chord Imaginary Line drawn from the leading edge to the trailing edge of an airfoil Lift Upward force that opposes gravity Angle of Attack Angle between the chord line and the relative wind Critical Angle of Attack The point at which a wing will stall Stall Airflow breakaway from the surface of the wing creates a loss of lift, occurs with an angle of attack around 17° Pitch Rotation around lateral axes of an airplane Yaw Rotation around vertical axis Roll Rotation around the longitudinal axis Ailerons Surfaces on the ends of wings-when one moves up, the other moves down. Ailerons control roll Elevator Surface on the horizontal stabilizer of an aircraft. Changes pitch. Rudder Surface on the vertical stabilizer of an aircraft. Moves the aircraft right or left (yaw) Flaps Surfaces on the wings used to generate lift True or False: A propeller creates lift True Function of a Tow Plane To tow a glider behind it on a cable and release it at an appropriate altitude Aspect Ratio Ratio between wingspan and chord length Wingspan Distance from wingtip to wingtip Convection Fluid motion between regions of unequal heating Average Lapse Rate 5.3°F per 1000 ft altitude increase First Manned Flight Paris: November 21, 1783 (Mongolfier Brothers in their hot air balloon) Envelope Main body of a hot air balloon Gore One of the several vertical panels making an envelope Thermistor Instrument that measures temperature in the envelope of a hot air balloon Hot Air Balloon Instruments Altimeter, vertical velocity indicator, thermistor Attitude Indicator Uses a gyroscope to give an artificial horizon Cycle Recurring series of events
