The servovalve includes a primary jet of fluid. A variable control signal is adapted to vary the angular position of the primary jet from its maximum recovery position. A first fluid path is adapted to supply fluid to a servopiston at a variable pressure determined at least in part by the control signal. A second fluid path is adapted to receive a ...

In this-report we present a FORTRAN IV programme for fitting cubic splines by Least Squares to data given-at arbitrary points. The algorithm used was first given by J.Go Hayes and Jy Halliday [lJ. Representation of cubic spline by means of B-splines and the use of Householder13; transformation in obtaining the least squares solution13; are two of t...

Problems are encountered in the determination of in-flight power of turboprop engines which are not fitted with a direct torque measuring device. Elaborate investigations were carried out on such an engine to estimate its performance during its service with fleet. The present paper describes the special tests and their results to determine the effe...
