✦ Synopsis
Zeppelin models was retested.
These tests were made at tank pressures varying from I to 20 atmospheres, and the extreme range of Reynolds Number was about I,OOO,OOO to 40,000,000.
The lift, drag, and moment coefficients of the models were determined, and the effects upon these coefficients of pitch, fineness ratio, scale, surface texture, initial degree of air-stream turbulence, and the effects of the addition
