Dec 10, 2016 · To determine power required, the equation P R = 1 2 ρs C D0 3 + W 2 0.5ρsπARe V -1 was used. ρ is the air density at each altitude for which power required is calculated, s is the wing area, AR is aspect ratio of the wing, previously discussed, and e is the Oswald efficiency factor. C D0 was calculated in task 1 to be 0.0265. The power required at each altitude will be different due to ...

In order to find the optimal aircraft design (i.e. the one with the minimum GTOW), Team V calculated and plotted various constraints along the aspect ratio curves. The constraints used were stall speed, cruise speed, climb rate, takeoff distance, and turn load factor (n) value.

High aspect ratio wings with low taper ratios (tip chord much less than root chord) are extremely prone to tip stalls so it is best to avoid using both on the same wing. If you want a highly tapered wing then keep the aspect ratio down. If you want a high aspect ratio wing then keep the taper ratio closer to 1 (same root and tip chord).

AR is the aspect ratio, e is Oswald’s efficiency factor, and S is a characteristic area. Our goal in this is to examine 2 conditions of interest: Minimum Drag, which . maximizes the range (distance traveled) of an aircraft. Minimum Power, which . maximizes the endurance (time aloft) of an aircraft. Part 1:

An aspect ratio of 7.6 could be found in most general aviation – single engine aircraft. However, upon conducting a trade study to see how drag is affected by changing the aspect ratio, it was found that a lower aspect ratio of 5 is more desirable. This new aspect ratio of 5 gives a lower parasite drag and thus lower thrust loss and greater ...

The actual angle of attack is a function of the lift coefficient, wing planform and the aspect ratio. Α 0 is angle of attack from airfoil infinite aspect ratio plot at given Cl. AoA= A 0 + 18.26*Cl *(1+tau) AR Degrees

The wing uses a single airfoil, the NACA 4415, for high lift coefficient(1.866) in low Reynolds number flight and an average thickness of 14.994 percent and a camber of 3.974 to compensate for the storage, and extension of flaperons, which act as ailerons, flaps and spoilers for the aircraft. Our wing has an aspect ratio of 11.3, a taper ratio ...

a. Aspect Ratio is the relationship between the wing chord and the wingspan. A short wingspan and wide wing chord equal a low aspect ratio. b. Drag Divergence is a phenomenon that occurs when an airfoil's drag increases sharply and requires substantial increases in …
