description abstract	INTRODUCTION A cascade of airfoils may be employed to deflect an air stream with relatively small loss of available energy. With proper geometric arrangement, the deflection of the air stream is also accompanied by a considerable decrease in velocity. As part of the program to study duct-inlet problems, an investigation was made to determine the feasibility of incorporating a cascade of airfoils as an integral part of a fully submerged intake. It was reasoned that, if an efficient cascade of airfoils were combined with an NACA submerged inlet (reference 1), the resultant air-induction system would diffuse and deflect the air in a minimum of space and still give a reasonable ram-pressure recovery. The investigation discussed here was preliminary in nature and was meant to serve as a guide for future research. Only the more important variables of airfoil-cascade and submerged-inlet design were considered.
