TM 1-320, TECHNICAL MANUAL OF AIRSHIP AERODYNAMICS (11-FEB-1941)

TM 1-320, TECHNICAL MANUAL OF AIRSHIP AERODYNAMICS (11-FEB-1941)., This manual is designed as a text for the· instruction of airship student pilots and as a reference text for the rated pilot. Accordingly the subject has been so approached as to · give the knowledge of aerodynamics essential to the operation of airships. Intricate formulas involving higher mathematics, although valuable to the designer, are of secondary importance to the pilot. Such formulas therefore have been omitted and the entire subject so treated as to bring. out basic principles and their application to lighter than air aircraft operation.
