Bill Flanagan presents the history of flight testing the Northrop Flying Wings from the N-1 to the B-2. Produced by Jarel and Betty Wheaton for Peninsula Seniors www.pvseniors.org
When I was growing up in Durham, California, I can remember walking in my Grandfather's fields and watching the "Fly Wing" flying up the East side of the Central Valley. What a great plane.
you forgott the rear rudder from the birds and they full active wings with "automatic stability controll" , in comparison was the northrop, or the Horten flying wings extremly primitive designs...the only flying wings who was always safe to fly, was the Fauvel (design use on many gliders from 1933 up today), but they need vertical controls, and not usable to fly high speeds...
19:35 Spin recovery in conventional aircraft it is a No-No to use ailerons to get out of a spin. That produces adverse yaw which is spin inducing. Generally neutralize ailerons and you use only Rudder to stop the auto rotation.
Spin recovery for military aircraft seems more variable... for modern ones, applying ailerons into the spin is often mentioned, while ailerons against the spin is mentioned in reference to some 40s and 50s airplanes: "Modern military fighter aircraft often tend to require yet another variation on spin recovery techniques. While power is still typically reduced to idle thrust and pitch control neutralized, opposite rudder is almost never used. [..] The preferred recover technique has a pilot applying full roll control in the direction of the rotation" - Wikipedia "For modern military aircraft, with low-aspect-ratio wings, which are fuselage heavy, the primary spin recovery control has been aileron with the spin, supplemented with rudder against the direction of rotation." "Full aileron into the direction of spin. Full aft stick. Full opposite rudder." - reported in a forum post to be the spin recovery procedure for the T-38, said to have "strange" spin characteristics "Full rudder opposite to the direction of spin followed by forward stick will stop the spin quickly. Slight aileron movement opposite to the direction of spin adds appreciably to the speed of recovery" - 1955 article about the F-89C "Apply full opposite controls sharply, leading with opposite rudder, and follow by applying full forward stick. Apply ailerons _against_ the spin." - F4U-4 flight manual
