![]() Speed of Sound When a plane travels faster than 760 a sound barrier forms in front of the Sound Waves Sound is made up of molecules of air which move. The sonic boom sounds when the plane is going faster than 760 Is the result of breaking through the air waves which form in front of a fast Sonic Boom When a plane pushes through a shockwave it creates a sonic boom. To travel faster than sound the plane must push through these waves. Stability and Control Stability and Control is the study of how to control the speed, direction,Īltitude and other conditions that affect how a plane flies Shock Wave A series of air waves that form in front of a fast moving plane. Spoilers The spoilers are used like air brakes to reduce any remaining lift and slowĭown the airplane. This helps to increase the lifting force of the wing at slower speeds like Slats The slats move out from the front of the wings to make the wing space larger. The left and right movements of the plane. Rudder The rudder is found on the tail of the plane. The wing with the lowered aileron rises while the Hypersonic: 3500-7000 MPH Roll To roll the plane to the right or left, the ailerons are raised on one wingĪnd lowered on the other. Regimes of Flight The ranges of speed that airplanes fly. Propulsion (as a field of study in relation to Aeronautics) is the study of how toĭesign an engine that will provide the thrust that is needed for a plane to Raising the elevatorsĬauses the airplane to climb. The airplane's nose to drop, sending the plane into a down. On the tail to make a plane descend or climb. Pitch Pitch is to make a plane descend or climb. The engine passes through the exhaust and produces the thrust or forward motion Nozzle The nozzle is the exhaust duct of the engine. Processing the air in this way, the engine is a little more quiet. Mixer This part of the engine combines the high temperature air coming from theĮngine core with the lower temperature air that was bypassed in the fan. Materials and Structures The study of what materials are to be used on the plane and in the engineĪnd how those materials make the plane strong enough to fly effectively. When a plane travels faster than this speed it is breaking the Of the same size in the opposite direction. ![]() When an object is pushed in one direction, there is always a resistance.Objects will move farther and faster when they are pushed harder.Object is moving, it will not stop or change direction unless something If an object is not moving, it will not start moving by itself.Laws of Motion - Sir Isaac Newton proposed three laws of motion. An example of this speed is the Space Shuttle. RocketsĬan travel 5 to 10 times faster than the speed of sound. Hypersonic This is the speed of flight that is used by rockets in outer space. Gravity a force that pushes objects come down to the earth. Fuselage The body of the plane Gas Turbine Another term for engine. Fin is the vertical part of the tail Flaps The flaps slide back and down to increase The large spinningįan sucks in large quantities of air. Fan The fan is the first component of the turbofan engine. On the direction of that the elevators are moved. Elevators are found at the rear of the plane. Drag Resistance that slows an object down in the air. The air and creates an increase in the air pressure. Of fans with many blades and it is attached to the shaft. Compressor The compressor is the first component in the engine core. ![]() Oxygen in the compressed air, producing hot expanding gases. Results in high temperature, high-energy airflow. Combustor In the combustor the air is mixed with fuel and then ignited. Ailerons They are hinged on the wings and moveĭownward to push the air down and make the wing tilt up. Up of molecules which are constantly moving. ![]() Air Air is a physical substance which has weight and is made Aerodynamics The study of how air flows around the airplane. Vocabulary Aviation Aeronautics is the study of the science of flight. ![]()
