 INERTIA Newtons 1st Law Object at rest stays at rest unless acted upon by an outside force ACCELERATION The rate of change of velocity over time SPEED Rate of movement or motion in a given amount of time VELOCITY The quickness or speed of an object in a given time or direction Newtons 1st Law Inertia an object at rest will stay at rest, or an object in motion will continue in motion at the same speed and in the same direction, until acted upon by an outside force Newtons Second Law Force An object moving w/uniform speed is acted upon by an external force, the change of motion, or acceleration, will be directly proportional to the amount of force and inversely proportional to the mass of the object being moved Newtons Third Law Action and Reaction For every action there is an equal and opposite reaction Bernoulli's Principle The principle states that when a fluid flowing flowing through a tube reaches a constriction is increased and its pressure decreased Wind Warning minimize loss and damage from destructive weather Small Craft Winds 33 Knots or less Gale winds 34-47 knots Storm winds 48 knots or greater Tropical Cyclone warnings 3 stages of intenstity 1.tropical depression- winds 33 knots or higher2.tropical storm-winds 34-63 knots3.hurricane/typhoon-winds 64 knots or greater Thunderstorm/ Tornado Warnings Thunderstorm warning- within 3 miles of airfield, or in immediate area Severe-wind gusts 50 knots or greater and/or hail Tornado- tornados detected by RADAR Lift Force that acts in an upward direction to support aircraft in air Must be greater than or equal to weight if flight is to be sustained Weight Force of gravity acting downward on the aircraft and everything on aircraft Drag Force that tends to hold aircraft back Drag resist motion Thrust force developed by aircraft engine Must be greater than or equal to the effects of drag to fly Longitudinal axis imaginary referance line running down the center of the aircraft between nose and tail roll Lateral axis imaginary reference line running parallel to the wings about which pitch occurs Vertical axis imaginary reference line running from top to bottom of aircraft. yaw 3 primary movements of aircraft about the axis pitch- up and downyaw-right and leftroll- wing tips, one up the other down Fixed wing aircraft primary flight controls ailerons control longitudinal axiselevators control lateral axisrudder controls vertical axis Rotary wing aircraft primary flight controls collective stick controls up and down cyclic stick tilits rotor blades forward aft or sideways lateral control(foot pedals) controll blades on tail rotor Flap reduces landing speed Spolier use to decrease wing life Speed brakes hinged or moveable control surfaces used for reducing the speed of aircraft Slats (boundary layer) Intended primarily for use during operations from carriers; catapult takeoffs and arrested landings Horizontal stabilizer provides stability of the aircraft about it lateral axis Vertical stabilizer directional stability base to which rudder is attached Tail rotor counteracts the torque action of the main rotor by producing thrust in opposite direction angle of attack angle at which a body, such as an airfoil or fuselage, meets a flow of air autorotation method used allowing a helicopter to land saftley from altitude w/out using engine power, useing reverse airflow through rotor system to reduce rate of decent Components of basic hydraulic system reservoir- holds fluidpump- flowtubing- transmits fluidselector valve- direct flowactuating unit-convert fluid presure AuthorJulieana ID59109 Card Set107 DescriptionAVIATION FUNDAMENTALS Updated2011-01-11T10:56:50Z Show Answers
