Louvred Port Covers

A project log for 'Bird of Prey II' Super Long Range VTOL UAV

Flight time and versatility will be vastly extended using a combination of multirotor, blended wing, and hydrogen fuel cell technologies. 12/21/2017 at 10:330 Comments

Louvred port detail

The root of each louvre section as well as the central fixed spar are attached to the hard plastic porthole sleeve that passes through and reinforces the porthole where the vertical thrusting axial pair are mounted. A moving spar is actuated by a servo to open and close the louvre.

Port covers on the top of the UAV wing are open or closed.

Port covers on the bottom of the wing are controlled using the pitch and yaw signals while in VTOL mode, and are closed in forward flight mode. The pitch control in VTOL mode will help accelerate the UAV to the necessary forward flight speed, while maintaining adequate lift and yaw manuevering through vertical thrust vectoring.
