Calibration of Torque and Thrust Instrumentation for the Boeing Turboprop
MetadataShow full item record
For the new set-up for torque and thrust measurements on the Boeing turboprop which was completed in April 1963, calibration was carried out by recording strain gage instrument readings for known torque moments and thrust loads...

Henderson, Lee Herman (Monterey, California ; Naval Postgraduate School, 1971-09);The thrust and torque were measured and the efficiency calculated for a 14.6-cm diameter, two-bladed propeller in aqueous solutions of polyethylene oxide, WSR-301, with concentrations ranging from 0 to 75 wppm (weight ...
Flanagan, David B. (Cambridge, Massachusetts; Massachusetts Institute of Technology, 1962-06);The object of this study was to determine the feasibility of automatically controlling propeller pitch to reduce RPM fluctuations caused by variations in propeller speed of advance. The investigation was made ignoring ...
Flood, Kevin M. (Cambridge Massachusetts Institute of Technology, 2009-06);Propellers are typically optimized to provide the maximum thrust for the minimum torque at a specific number of revolutions per minute (RPM) at a particular ship speed. This process allows ships to efficiently travel at ...
