NASA AD-1 (Ames Dryden -1) je bil NASIN projekt eksperimentalnega letala s poševnim krilom, ki so ga izvajali med letoma 1979 in 1982 v Dryden Flight Research Center, Kalifornija. Uspešno so dokazali koncept, da lahko zrakoplov leti s "pivotirajočim" (poševnim) krilom z naklonom od 0° do 60°.
Koncept je deloma podoben gibljivem krilu, pri gibljivem obe krili hkrati spremenita naklon. Pri AD-1 pa samo eno krilo "pivotira" okrog sredinske točke krila. Letalo tako postane asimetrično.
Letalo je poletelo 79-krat. Pri tem so testirali aerodinamiko pri različnih naklonih in hitrostih.
Prvi krilo takega tipa je predlagal Richard Vogt leta 1942 in sicer na letalu Blohm & Voss P.202.
