ASCI 309 Aerodynamics Week 1

I’m working on a Engineering question and need guidance to help me study.

The first part of this module week’s assignment is to research a turbine-powered (i.e., jet-type) aircraft, Boeing 737.

Keep in mind that any theoretical solution to a complex, unique real-world problem is based on models and generalizations, requiring certain assumptions and simplifications, and comes with a variety of limitations as to its applicability. Therefore, detailing conditions and selections is a fundamental part of a scientifically sound approach and documentation of your solution to the problems.

After you have selected the aircraft you will use for the assignment, complete the following exercise: (Document is attached)

For part two of this module week’s assignment, select and research a common jet-type transport aircraft (later in the course we will get into more details of the differences between power-producing and thrust-producing propulsion systems, but for now, the main point is to have thrust directly as a force available for the introductory analysis of rectilinear motion).

For your selected aircraft, research and present the following information in your instructional presentation:

  1. Selected aircraft
  2. Maximum takeoff weight (MTOW)
  3. Engine type, number, and rated thrust, as well as total available thrust (sum of all engines)
  4. Takeoff distance at MTOW

Utilizing the above-researched information, derive and present (in an instructional way) approaches and solutions to the following problems:

  1. If your selected aircraft’s takeoff speed at MTOW was assumed to be 150 kts (i.e., the speed that is reached in the above-researched takeoff distance), explain how to find and determine:
    1. The total acceleration a [ft/s2] during the takeoff roll
    2. The sum of retarding forces FR [lb] (drag + friction) that was present during takeoff
    3. The time t [s] it took for this takeoff
  2. Given the researched knowledge about the aircraft’s thrust, explain for a specific airspeed example of how to determine the power P [HP].
  3. For a specific example related to your researched aircraft data, explain how to determine potential EPot [ft-lb], kinetic EKin [ft-lb], and total energy ETot [ft-lb].
  4. For a specific example, explain how the minimum required climb angle AOC [deg] to clear an obstacle can be calculated from knowledge about the obstacle’s height and its distance from the point of takeoff.

Common Errors

  • Mixing of different systems of measurement (metric and British)
  • Not converting into consistent units where required (e.g., kts into ft/s)
  • Confusing weight (a force in [lb]) and mass (in [slugs])
  • Wrongly applying trigonometric relationships
  • Incorrect calculator/tool setup (e.g., radian vs degree) and/or use (e.g., not properly accounting for prioritization of operations)

Assignment Guidelines

  • You must show all calculations (make sure your work is legible) to receive full credit.
  • In contrast to formal research for other work in your academic program at ERAU, Wikipedia may be used as a starting point for this assignment. However, do not use proprietary or classified information even if you happen to have access to your line of work.
  • Combine and submit all of the pages into a single file (Microsoft Word or Adobe PDF).
