SHROUDED PROPELLER TEST PROGRAM COMPUTER PROGRAM. VOLUME 2
Abstract
Hamilton Standard computer deck numbered H193 is used to calculate shrouded propeller performance and shroud surface pressure coefficients based on the computational procedure discussed in Volume 1 of 'Shrouded Propeller Test Program - Method Development.' The necessary shroud thickness and camber effects are generated by Hamilton Standard Deck H194, and the pertinent centerbody information is obtained from Hamilton Standard Deck H060. Therefore, data generated by Decks H194 and H060 are used as input for Deck H193. The computations permissible with Hamilton Standard Deck H193 are divided into the following three categories. (1) Given Shroud and Propeller Geometry--For a given shroud and propeller geometry, an iterative process is involved in establishing the propeller circulation for the specific operating condition. Then, the net shrouded propeller (shroud + propeller) performance is computed as well as the shroud and propeller contributions to the performance. Shroud friction drag and shroud surface pressure distributions are also calculated. (2) Given Shroud Geometry and Propeller Circulation--For a given shroud geometry and propeller circulation, the same output as noted above is obtained. (3) Given Shroud Geometry (No Propeller)--For a given shroud geometry, the shroud surface pressure coefficients, the shroud drag, and velocity induced by the shroud in any plane in the shroud are computed.
