There is an airfoil with a 3ft chord length for a small remote
controlled aircraft. The lift coefficient is C = 0.59 and the
pitching moment coefficient at a quarter chord length is
Cm,c/4 = -0.032 for a landing spped of 45 ft/s at
sea-level std conditions
a) Calculate the lift per unit span (in lbf/ft)
b) Calculate the moment about the quarter chord position per
unit span
c) Calculate the moment about the leading edge per unit span

Buckling is a problem for sheet metal used on aircraft skins and
wings. Traditionally the skin has been riveted to the structure;
however, there are manufacturing methods that allow bonding of skin
composite panels. Select an aircraft: narrow-body or wide-body and
if aluminum or composite skin used, discuss how this will affect
the buckling mode and ultimately the service life.
Meals on Wings Inc. supplies prepared meals for corporate
aircraft (as opposed to public commercial airlines), and it needs
to purchase new broilers. If the broilers are purchased, they will
replace old broilers purchased 10 years ago for $150,000 and which
are being depreciated on a straight line basis to a zero salvage
value (15 year depreciable life). The old broilers can be sold for
$60,000. The new broilers will cost $180,000 installed and will be
depreciated using MACRS over...
