[理工][航太][航空工程概論]-成大96-航太工程在職專班
1.Conside an airplane of speed V in a level turn of radius R and with a roll
angle ∮ .Define the lift load factor n=L/W. Show that the turn radius can
be expressed as: R=V^2/g√n^2-1 (g根號n平方減一)
2.The figure below shows an airplane flying in the vertical plane and its
free body.The forces acting on the plane are its weight W,the thrust T
exerted by its engines, and the aerodynamic forces,which are resolved into
a component perpendicular to the path,the lift L,and a component parallel to
the path,the drag D.The angle r between the horizontal and the path is
called the flight path angle, and α is the angle of attack.If r=6度
D=125kN,L=680kN,and the mass of the airplane is 72000kg,what values
of T and α are nessary to maintain steady flight?
