GATE Aerospace Engineering 2009 - Velocity Vector Components (u,v,w), Angle of Attack & Sideslip Relation

Aerospace Engineering > GATE 2009 > Kinematics

The velocity vector of an aircraft along its body-fixed axis is given by

If V is the magnitude
of &vec;V, α is the angle of attack and β is the angle of sideslip, which of the following set of relations is
correct?

u=V sin β cos α; ν=V sin β; w=V cos β sin α

μ=V cos β cos α; v=V cos β; w=V cos β sin α

u=V cos β cos α; ν=V sin β; w=V sin β sin α

u=V cos β cos α; v=V sin β; w=V cos β sin α

Correct : d
