A vehicular lift wing having a Coanda edge perimeter, is provided with a nozzle slot formation from which fluid ejection is directed tangentially from the full Coanda edge perimeter during translation through an ambient fluid medium. Omnidirectional control means supplies pressurized fluid to the nozzle slot formation at different azimuthal locations along the Coanda edge perimeter for selectively controlled generation of dynamic forces exerted on the wing.
