where the jet velocity Is obtained by integration of the expression 

 dVjmn 



dt 



= 0.035 (Tp„„. 1,91 Vj^JVj^nl) 



The forces on the body due to pressure distribution changes are a 

 function of the jet velocity alone and are expressed as 



Tbmf= 0.655 Vj^JVj„f|(T* - 2.93) 



Tbma= 0-655 V^^,|V3,J{T2* - 2.93) 

 The resulting forces and moments on the body are then expressed as 

 Xthrmf= 0.655 vfmf T 3* 

 Xthrmo= 0.655 vf„^T4*
