MAE 251 test 1 review sheet

MAE 251 test 1 review sheet (material we have covered) Please review this outline and come to class prepared with questions. I’ll have a basic overview of material • Anatomy of an airplane o Understand the basic components that make up an airplane and be able to describe what their purpose is on the airplane • Fundamentals of physical quantities o Pressure o Temperature o Density o Equation of state • The standard atmosphere o How is the standard atmosphere defined o Understanding the types of layers ▪ Isothermal ▪ Gradient region o Types of altitude ▪ Geometric ▪ Absolute ▪ Geopotential ▪ What is the difference between them ▪ How to convert between the three o How is each quantity calculated at altitudes? (Pressure, Temperature, Density) o Standard sea level properties o Other important atmospheric properties and how they are calculated • Different types of flight and important performance parameters o What are aircraft parameters ▪ Angle of attack ▪ Pitch angle ▪ Lift – Drag – Weight – Thrust ▪ Understand how these are related in different flight conditions o Cruise flight (SLUF – steady level unaccelerated flight) ▪ How angle of attack and velocity interact • Angle of attack and pitch angle ▪ How wind effects flight path and be able to calculate ▪ Range and endurance ▪ Calculating flight times o Climb ▪ Rate of climb ▪ Angle of climb ▪ How they are affected by wind o Descent ▪ Similar to climb – also have gliding flight under descent
