Abstract:
The Report gives experimental results obtained on four flights on R.26 during the period November, 1918-January, 1919. The following earlier Reports are quoted in the text :- R. & M. 668 (Airship R.33) ; R. & M. 537 and R. & M. 619 (23 Class Airships) ; R. & M. 460 and R. & M. 475 (Airscrew Thrust). The experiments may be classified under the following headings: (1) Unsuccessful attempt at pressure measurement over the horizontal stabilizing surfaces. (2) Turning trials with the rudders at 12° and 18°, port and starboard, for one speed only. See Tables 2 and 3, Figs. 2 and 3. (3) Deceleration tests from full speed. See Table 4, Fig. 4. (4) Airspeed for a number of combinations and rotational speeds of the engines. See Table 5. (5) Preliminary observations of airscrew thrdst by the method suggested by Dr. Stanton in R. & M. 460. See Appendix and Tables 6 and 7, Figs. 5 and 6.
