The Secret of Flight - Season 1 Episode 9 Эпизод 9
The first airplane to fly was what would be called today a Canard Type airplane; it had a horizontal stabilizer in front of the main wing. Today’s Conventional Type plane has the stabilizing surfaces are of the same size. Dr. Lippisch explains all three models. He also describes the Allwing Type plane which is made by combining wing and tail surfaces, sweeping the wing tips backward, and placing the control areas on the wing tips. He discusses the fundamental law of stability and demonstrates this on models in flight and in the Smoke Tunnel.
