Thrust vectoring on a VTOL capable wing
Thrust vectoring is a technique that allows an aircraft to change the direction of its thrust without changing the orientation of its propulsion units. This can enable vertical take-off and landing (VTOL) capabilities, as well as enhanced maneuverability and agility in flight.
One example of a VTOL capable wing with thrust vectoring is the modified SU 47 built by RC Wing specialist René Rosentraeger.
This impressive Harrier-like jet can take off vertically using two ducted fans that are mounted on the wingtips and can be angled downward by ventral flaps. The fans can also be used to control the pitch, roll and yaw of the aircraft during hover and transition modes.
The following video shows the VTOL wing in action:
The thrust vectoring system is powered by two brushless motors that are connected to two electronic speed controllers (ESCs). The ESCs are controlled by an Arduino Nano board that receives signals from a radio receiver. The Arduino board also controls two servos that move the ventral flaps.
The following video shows how the internals work to enable thrust vectoring:
Rosentraeger's VTOL wing is a remarkable example of how thrust vectoring can be applied to a fixed-wing platform with minimal actuation and complexity. It demonstrates the potential of hybrid configurations that combine the advantages of both rotorcrafts and fixed-wing aircrafts.
