A method of propulsion and attitude control in fluid environments is disclosed by examples of preferred embodiments of vehicles utilizing said methodology. The preferred embodiment of a vehicle utilizing said invention comprises at least one pair of left and right wing assemblies of an airfoil profile separated by a fuselage that combine to form a fluid dynamic body. Each wing assembly houses within its interior at least two longitudinally adjacent, counter-rotating drive-fans mounted on fixed approximately vertical axes that are capable of being powered by various means. Each wing assembly has operable interior and exterior venting means that control fluid flow to, from and between respective drive-fans. Each wing assembly has control surfaces at its trailing edge and is itself hinged to the fuselage with means to change the dihedral of the wing assembly. Each wing assembly has surfaces of designed permeability that create a dynamic laminar flow envelope about the vehicle. The fuselage comprises a forward cockpit/cabin area and a fluid channel located laterally between left and right wing assemblies with means to control flow between said wing assemblies. The preferred embodiment may be constructed to any scale while using various construction techniques common knowledge to marine and aircraft construction, as well as easily modified to suit role and performance.
A method of propulsion and attitude control applicable to all fluid environments in which longitudinal propulsion is created by longitudinally adjacent, counter-rotating, drive-fans mounted on approximately vertical axes within airfoil wing assemblies which draw fluid from the ambient environment through controllable louvered vanes and vents, fixed structures of variable permeability, and door-like sub-wing assemblies located on the exterior of the wing assemblies as well as from vents arranged around the periphery of the cylindrical shrouds surrounding each drive-fan, fluid is then controllably exhausted by shroud venting means through exhaust vents at the aft and outer wingtips of the wing assemblies by the centrifugal thrust of the drive-fans, longitudinal propulsion as described is augmented by the swirl effect of the drive-fans on the surrounding ambient fluid medium as fixed permeable or controllable louvered vane intakes and exhausts that are located directly above and below the drive-fans are arranged such that the drive-fans are exposed to the ambient fluid medium at the aft-ward rotation of the drive-fans;
A vehicle that integrates at least one left and one right wing assembly with a centrally located fuselage to create a fluid dynamic body, the structural geometry of said vehicle utilizing the invention is substantially triangulated longitudinally and laterally, with the wing assemblies being constructed around cylindrical drive-fan shrouds, which are in turn arranged within a hexagonal-cell framework, the intersection of lines bisecting these hexagonal-cell structures serve as centers for the mounting of the drive-fans and drive components, wherever possible, lateral and longitudinal triangulation is used for strength and conservation of weight, while the geometry of the invention also allows for variable mounting points for vertical, structural triangulation where necessary, each respective wing assembly is of an airfoil profile that may be modified in camber, thickness and lateral curvature to suit specific performance and role requirements;
