A semi-aerobatic aircraft has reached its design diving speed of 185 m/s in a dive inclined at 45° to the horizontal ground. If the maximum maneuver load factor for the aircraft is 5.5, determine the height at which the pull-out from the dive must begin for straight and level flight to be achieved

Question

A semi-aerobatic aircraft has reached its design diving speed of 185 m/s in a dive inclined at [latex]45^{\circ}[/latex] to the horizontal ground. If the maximum maneuver load factor for the aircraft is 5.5, determine the height at which the pull-out from the dive must begin for straight and level flight to be achieved at a height of 500 m.

Accepted Answer

Assuming the design diving speed is maintained throughout the pull-out, from Eq. (13.16),

[latex]n=\frac{V^{2}}{g R}+1[/latex] (13.16)

[latex]5.5=\left(185^{2} / g R\right)+1[/latex]

so that

[latex]R=775.3 m[/latex]

Referring to Fig. 13.11,

[latex]a=R-R \cos 45^{\circ}[/latex]

Substituting for R from the preceding,

[latex]a=227 m[/latex]

Therefore,

[latex]h=727 m[/latex]
