Need to complete questions below, no conclusion necessary can use the i-v or i-vi system to locate questions i. Provide in-depth examples of Newton’s three laws applied to an aircraft engine. Using the appropriate equation, find the thrust produced in N for an engine capable of accelerating 200 kg of airflow at 50 m/s2. ii. Show and analyse the energy flow in an aircraft piston engine with an appropriate diagram. Describe the Otto cycle. iii. Compare a turbojet engine with a high by-pass turbofan engine. What are the differences between turboprop and turboshaft engines? iv. Write the equations and then calculate the distance fallen after 4 seconds for a freely falling object starting from rest? v. What will be the speed of an aeroplane that flies typically at 210 km/h when it encounters a 75 km/h wind from the side (at a right angle to the aeroplane). (You should show the diagram and the equation) vi. The frequency of a wave is 50Hz. What do you mean by this? i. Show and explain in two diagrams the main forces of an aircraft in level, unaccelerated flight, and an aircraft established in a climb. Does the amount of lift in a climb increase or decrease compared to straight and level? Briefly describe how the aircraft thrust is created. ii. Describe how Archimedes’ principle is applied to balloons and airships. iii. Draw section geometries of an aircraft wing and describe the different wing components. Demonstrate what the chord line is and approximate the mean camber line of the wing. Discuss how wing camber influences the lift of an aircraft? Discuss why a modern airliner has extra devices on the leading/trailing edges of the wing (such as slats, slots, and flaps) for take-off and landing. iv. In an electrical circuit, the current is 2A, and the voltage is 24V. Draw the circuit, write the equations, and find the resistance and power. v. Discuss a relative comparison between a subsonic and a supersonic aircraft.
