Summary:

The need for a "flying-test bench" to enable measurements of flight resistance, engine and propeller power and efficiency to be made during flight was experienced in interested circles as early as 1915, and it grew in proportion to the constant demand for increased flying capacity in our military types of aircraft. The problem was worked out in various ways by the German Aeronautical Laboratory (D.V.L.) at Adlershof. Unlike the method observed in the actual flying test-bench, where engine must be so installed that it can work freely, a dynamometer hub was inserted between the engine and the propeller by the D.V.L. It was approved as an accurate measuring device by the Propeller Testing Department of the Technical Section of Aviation (Flz.) at Adlershof, and was accordingly constructed there
