ENAE283 Homework #5 Due Saturday, 7/1/22 by 11:59PM
For all homework assignments in this course, you are required to submit fully-
explained solutions, indicating the sources for any
numbers and equations used. Boxed areas are provided for your final answers. If you cannot use this document directly as your worksheets, please work neatly on your own paper. Include a header on each page like the ones shown, write the problem statement at the top and box your final answer at the lower right corner. Pay attention to appropriate significant figures in final answers.

(1-11) You have a choice for this portion of the HW: you can study the performance characteristics of a propeller driven airplane (Beechcraft Bonanza) or a twin jet attack aircraft (Fairchild Republic A-10). Pick one and then follow through the whole series of problems relating to that airplane. Each of these problems is most easily accomplished by employing a spreadsheet tool like Excel, since all of the calculations are repeated at different velocities and altitudes. Your Excel spreadsheet or MATLAB arrays should contain the following calculations. 𝑉𝑉

The only variable that changes is the density between Sea Level and altitude. Besides changing the thrust/power required curves via the 𝑞𝑞

Important instruction: These questions use the last three-digit value (L3D) of individual student matrix numbers. For example, if the matrix number is CD180264 then the L3D value is 264 (since the last three digits is 264). Some data require multiplication of the L3D value, for example, 10(L3D) means 10 x L3D

Hi, I need help with the first part of the problem below because I'm very confused about how P1 and P2 should be calculated. If you look at my notes to solve the problem there is already a formula in place as I always thought the Patm should also be multiplied by the Area in the numerator, but it's not if I look at this specific tutorial solution given by my course but it's not explained why. I have done a while ago a very similar problem with using that formula in my notes and it gave me the right results, but it's not working for this one. Could you please help me understand why as I have a test coming soon?
