Helicopter Performance Computer Programs for HP-41 Hand-Held Computer

摘要

This document has reference tables and programs used to evaluate helicopter performance in the areas of: Autorotation; However, Service and Combat Ceilings; Basic Power Required Parameters; Fuel Consumption; High Speed Effects; Basic Power Considerations; Maximum Endurance Power/Velocity; Maximum Rage Power/Velocity; and Weight Estimation Relationships. These programs present the user of the HP-41 hand-held, programmable calculator with a series of self-prompting, alphanumeric programs that can be used with acceptable results to compute and evaluate helicopter performance. Most of the programs are structured so as to be more expedient when doing preliminary helicopter design where intermediate values are of less a concern than would be the case when studying detailed performance.
