A sliding-arm whirling wheel thruster includes first and second whirling wheels and a housing. The first whirling wheel is disposed about a first rotational axis, and the second whirling wheel about a second rotational axis parallel to the first rotational axis. The housing comprises an arc over an enclosed space into which the first and second whirling wheels fit. The air blown outward by each of the whirling wheels is amassed inside the housing so as to make a pressure difference between inside and outside of the housing. The relative position of the first rotational axis to the second rotational axis is configured to be controlled. The airborne vehicle is lifted by buoyant force caused by the pressure difference.
