Range and endurance of turboprop, turbofan, or piston--propeller aircraft having wings with or without camber

摘要

New analytic expressions, based on the exact performance relationships without making the approxima- tions on which the classical Breguet equation is based, are developed to predict cruising range and endurance of turboprop, turbofan, or piston--propeller aircraft at constant speed and altitude. Also, the optimal cruising speed to achieve maximum range is determined.
