National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Flight Test of the Aerospatiale SA-342 Helicopter.

Abstract	The Eustis Directorate of the U.S. Army Air Mobility Research and Development Laboratory conducted an evaluation of the Aerospatiale Model SA-342 during November 1974. A total of 10 hours 20 minutes of flight time was accumulated during give test flights. Performance, stability, and control tests were performed to evaluate the increased capabilities of the SA-342 over the SA-341 upon which the design of the SA-342 is based. Both helicopters have fan-in-fin type antitorque control. The SA-342's handling qualities wwere generally very good, and it fin type antitorque control. The SA-342's handling qualities ere generally very good, and it exhibited improved lateral-directional stability over the SA-341; however, trimming the aircraft directionally within the 'sideslip deadband' was still difficult. The improved fan provided sufficient control moment to attain 50 knots in sideward flight. It is recommended that additional effort be expended to explore and resolve problems with the fan-in-fin design experimental both by Aerospatiale and by Sikorsky Aircraft.
