GUST ALLEVIATION STUDY PART. Ⅳ.ESTIMATED INDICIAL LIFT RESPORNSE OF FLAP AND SPOILER CONTROL DEVICES AT SUBSONIC SPEEDS

摘要

METHODS OF- OBTAINING THE INDICIAL RESPONSES OF FLAP TYPE AND SPOILER TYPE LIFT CONTROL DEVICES IN SUBSONIC COMPRESSIBLE FLOW ARE DESCRIBED, AND RESULTS ARE PRESENTED FOR SEVERAL TYPICAL CASES. THE FLAP RESPONSES WERE DERIVED WITHIN THE FRAMEWORK OF TWO-DIMENSIONAL SUBSONIC, LINEARIZED, COMPRESSIBLE FLOW THEORY BY THE APPLICATION OF A PERVERSE FLOW THEOREM TO RESULTS PREVIOUSLY DERIVED FOR COMPLETE AIRFOILS.
