Assy & Rigging -- FINAL EXAM

Assembly Def. - Answer- consists of putting together the major components of the aircraft Major Components of the Aircraft - Answer- fuselage, wings, empennage, nacelle, landing gear, and control surfaces Rigging Def. - Answer- consists of the alignment and the adjustments of those components Important considerations of Assy&Rigg - Answer- Understand the safety ramifications of the assembly and rigging process; Must be done in accordance with proper tech data Density - Answer- DEF: The mass per unit volume; Directly related to pressure, inversely related to temperature; Effects lift produced by the wing, as well as power produced by the engine Humidity - Answer- DEF: The mass of water vapor in a volume of air; Weighs 5/8 as much as dry air; Effects lift produced by the wing, as well as power produced by the engine Bernoulli's Principle - Answer- Stated - the total energy in a fluid (air mass) will remain constant; Explained - The "total' energy in an air mass consists of potential energy (static pressure) as well as kinetic energy (dynamic or ram pressure) Newtonian Physics - Proposed 3 laws - Answer- 1 -- Any mass in motion will remain in motion unless effected by an outside force; 2 -- Acceleration is directly related to force; 3 -- For every action, there is an equal and opposite reaction Forces acting on an aircraft in flight - Answer- Gravity - always down and perpendicular to the Earth; Lift - Always up and opposes gravity; Thrust - Always forward, and perpendicular to lift; Drag - always rearward, opposite of thrust; NOTE: in straight and level flight with no acceleration all are in balance with each other Airfoil - Answer- any shape designed to produce lift Chord - Answer- Imaginary straight line from the leading edge to the trailing edge Asymmetrical [Chord] - Answer- airfoil is different on both sides of the chord line Symmetrical [Chord] - Answer- airfoil is the same on both sides of the chord line Relative Wind - Answe
