The Effect of Spoilers on the Aerodynamic Force Characteristics of a Submarine Sail Configuration at Subsonic Speeds.

摘要

Analysis of the low speed wind tunnel data for a representative submarine sail configuration confirms that spoilers can be an effective mechanism for eliminating the snap-roll motion associated with turning submarines. Using a low aspect ratio symmetrical airfoil to simulate the submarine sail,spoilers with heights of 3, 5, 7and 9percent of the chord were mounted at locations ranging from 30to 80percent of the chord from the leading edge in 10percent increments. Sideslip angles of up to 13.5degrees were obtained with zero side force and consequently no rolling moment.
