Abstract
An air moving apparatus is formed by an outer box and an inner box made up of curved surfaces F. A plenum chamber F is created between the two boxes and is supplied with pressurised gas J via an inlet pipe E. A flow of gas G passes through two opposed and substantially parallel slits formed between curved surfaces H and lips X. The gas is exhausted through outlet B and passes over curved surface C. The gas flow induces a flow of ambient gas K which is entrained into the flow G and which is then exhausted at B. The apparatus may take the form of devices P and Q which can be deployed from aerofoil surfaces S and T. A combination of the devices may provide lifting forces for transition into hover from forward flight with a suitable low velocity aerofoil.
