16.00 Introduction to Aerospace and Design Problem Set #3 AIRCRAFT PERFORMANCE FLIGHT SIMULATION LAB Note: You may work with one partner while actually flying the flight simulator and collecting data. Your write-up must be done individually. You can do this problem set at home or using one of the simulator computers . There are only a few simulator computers in the lab area, so not leave this problem to the last minute. To save time, please read through this handout completely before coming to the lab to fly the simulator. Objectives At the end of this problem set, you should be able to: • Take off and fly basic maneuvers using the flight simulator, and describe the relationships between the control yoke and the control surface movements on the aircraft. • Describe pitch - airspeed - vertical speed relationships in gliding performance. • Explain the difference between indicated and true airspeed. • Record and plot airspeed and vertical speed data from steady-state flight conditions. • Derive lift and drag coefficients based on empirical aircraft performance data. Discussion In this lab exercise, you will use Microsoft Flight Simulator 2000/2002 to become more familiar with aircraft control and performance. Also, you will use the flight simulator to collect aircraft performance data just as it is done for a real aircraft. From your data you will be able to deduce performance parameters such as the parasite drag coefficient and L/D ratio. Aircraft performance depends on the interplay of several variables: airspeed, power setting from the engine, pitch angle, vertical speed, angle of attack, and flight path angle. Roughly speaking, the elevator control on an aircraft controls the angle of attack of the aircraft. The resulting pitch angle, airspeed, and vertical speed then depend on the power setting from the engine. 1. Introduction and Use of the Flight Simulator Spend time using Microsoft Flight Simulator 2000/2002 to learn to take off and fly an aircraft. We suggest that you use a simple single engine aircraft model (i.e., Cessna 182) since they are simpler and more stable than some of the other aircraft. Use the on-line tutorial as needed to help you learn what the basic controls and instruments are, and how to operate the aircraft in a stable way. At a minimum, you should be able to start the simulation, and control power, pitch, and roll angle to take off, fly on a straight heading, make shallow turns, climb, descend, and fly at a level altitude. 1 of 5

In addition to the on-line help in the flight simulator, we in the A/A department have set up a web page to help you get introduced to the flight simulator: http://web.mit.edu/aeroastro/flightsimlab/Introduction.htm 2. Airspeed and Vertical Speed Performance in a Steady Glide We will focus on collecting performance data from an aircraft in a steady glide. We will use a

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
