An integrated system for harvesting water from air includes an air propelling unit, a water condensation unit, and a fog harvester. The water condensation unit receives propelled air from the air propelling unit, and includes an airfoil designed to locally reduce pressure and temperature, thereby promoting water vapor condensation within the received propelled air. The fog harvester receives the propelled air with condensed water from the water condensation unit and collects the condensed water.

A lift control device actively controls the lift force on a lifting surface. The device has a protuberance near a trailing edge of its lifting surface, which causes flow to separate from the lifting surface, generating regions of low pressure and high pressure which combine to increase the lift force on the lifting surface. The device further includes a means to keep the flow attached around the protuberance or to modify the position of the protuberance in response to a command from a central controller, so as to provide an active control of the lift between a maximum value and a minimum value.

Thrust vector control for a vehicle having a fluid drive, vehicle having thrust vector control and method of controlling thrust vector. Thrust vector control includes a thrust current region for a thrust current of a propulsion stream having a flow direction; a steering mechanism for the thrust current including at least one steering device arranged at least in a peripheral region of the thrust current region, and the at least one steering device includes a rotational body with a lateral surface and a rotational axis arranged transverse to the flow direction, and the rotational body being rotatable so that a first part of the lateral surface exposed to the thrust current rotates in a first rotational direction, whereby a Magnus effect is produced to deflect the thrust current. The first rotational direction is in a direction of the thrust current.

A method for controlling a flying projectile which rotates during flight, comprising: determining an angle of rotation of an inertial mass spinning about an axis during flight; and controlling at least one actuator for altering at least a portion of an aerodynamic structure, selectively in dependence on the determined angle of rotation and a control input, to control aerodynamic forces during flight. An aerodynamic surface may rotate and interact with surrounding air during flight, to produce aerodynamic forces. A sensor determines an angular rotation of the spin during flight. A control system, responsive to the sensor, produces a control signal in dependence on the determined angular rotation. An actuator selectively alters an aerodynamic characteristic of the aerodynamic surface in response to the control signal.
