The purpose of this information report is to present the factors that affect the design and development of aircraft jet blast windshield rain removal systems. Rain removal system design will generally be unique to specific aircraft. Design of these systems typically requires a preliminary design for the system based on available empirical data to be followed with a laboratory development program and a flight test validation program. Published windshield rain removal performance test data is available only for limited windshield configurations.
This report presents information on the design and development of jet blast windshield rain removal systems for commercial transport aircraft. The information and methods in this report can also be applied to military and non-commercial aircraft jet blast windshield rain removal systems. Revision C is issued to align the document with current design practices, service experience and the SAE Style Manual.
