For your independent project, create an instructional presentation. Create a V-G diagram specific to your aircraft “Cessna 172” at a selected weight and atmospheric condition and explain how the V-G diagram can be utilized to identify specific maneuvering parameters. For inputs on how the V-G diagram is developed, review the discussion in the Flight Theory and Aerodynamics book (Dole, Lewis, Badick, & Johnson, 2017, pp. 229-235)
At a minimum cover the following aspects:
Positive and negative limiting load factor (i.e., the maximum G allowed for your aircraft)
Stall speeds at 1, 2, 3, and so on G up to the maximum positive G (at your selected weight)
Ultimate load factor (ULF)
Positive ultimate load (i.e., the actual force [lbs]) at the selected weight
The bank angle associated with the positive limiting load factor
For the specific maneuvering speed of your aircraft identified above, explain how to numerically find (provide the specific example and values) the associated turn rate and radius utilizing both of the following methods:
Rate and radius formula
The turn performance diagram (Figure 2.29 in Aerodynamics for Naval Aviators, Hurt, 1965, p. 179 or Figure 13.14, Dole et al., 2017, p. 239).
As in previous assignments, you will need to research a variety of additional information such as required formulas and pertinent aircraft data and/or assume a few parameters for your aircraft. Please make sure to detail those:
Bank angle to G relationship
Turn rate and radius
Stall speed under elevated G / bank
Necessary aircraft information:
Limiting load factors (positive and negative) for your example aircraft (from research)
Assumed aircraft weight
Utilize your previous module work to find 1G stall speed for your selected weight
Assume atmospheric conditions
Again, the emphasis in this project task is on explaining your methodology as if you attempted to instruct someone unfamiliar with the aerodynamic details and relationships. Therefore, make sure to detail all assumptions, all formulas used, and all steps that were taken.
