In the study or VTOL aircraft, the lifting fan is usually associated with fairly low values of jet velocity, in fact with velocities such that compressibility effects are not appreciable and therefore can be neglected. Some local compressibility effects may occur, at the fan tip, for instance, but such conditions should be avoided and need not affect consideration of the overall performance problem. Many important conclusions can therefore be reached by means of a simplified analysis which clearly illustrates the relationship between the significant parameters. In this simplified approach, consideration is given to the effects of duct losses and forward speed since both these factors are particularly important in the design of both VTOL aircraft and ground effect machines.
