What technical term, also slang for street, refers to the forces resisting the forward movement of an aircraft?
Forces on sails the surface, sailboats travel through water, which provides limited resistance to side forces. In a sailboat, side forces are resisted in two ways: All sailing craft reach a constant forward speed ("V") for a given wind speed ("V") and point of sail, when the forward driving force (F) equals the forward resisting force (R). For an ice boat, the dominant forward resisting force is aerodynamic, since the coefficient of friction on smooth ice is as low as 0.02. Accordingly, high-performance ice boats are streamlined to minimize aerodynamic drag. The approximate locus of net aerodynamic force on a craft with a
Bundeswehr Technical and Airworthiness Center for Aircraft Bundeswehr Technical and Airworthiness Center for Aircraft The Bundeswehr Technical and Airworthiness Center for Aircraft () or ( ("WTD 61")) is one of several testing centres of the German Armed Forces. Its tasks are the testing and evaluating of military aircraft and aerial weapon systems. The centre is also responsible for certifications and inspections of modifications made on aircraft already in service with the German Armed Forces. The Bundeswehr Technical and Airworthiness Center for Aircraft is not integrated into the command structure of the military branches of the German Armed Forces but is a branch of Federal Office of Bundeswehr
