Helicopter Engine Optimization for Minimum Mission Fuel Burn. This paper summarizes a study of a vast helicopter database that has been collected for the sizing stage of a preliminary design. analysis tool and has developed a helicopter sizing optimization methodology that enables a multi-mission design with LCC optimization. The final objective was to include all enabling processes, models and tools available for use in an Aeronautical Collaborative Design Environment, including the associated processes, models and methods. The combined approach is applied to conduct multidisciplinary design and optimization of a reference Twin Engine Light civil rotorcraft modeled after the Eurocopter Bo helicopter, operating on. The overall methodology is deployed for the design space exploration and optimization of a reference multipurpose twin engine light (TEL) civil rotorcraft, modeled after the Bo helicopter, employing two Rolls Royce Allison C20B turboshaft engines.

The search and rescue (SAR) mission designed for the purpose of this study assumes that the helicopter searches castaways at the sea, specifically, it flies rapidly to the search area and perform a search pattern for 30 min. It finally returns to the coast station where it starts up.
Among the many ways in which helicopter training is different than fixed-wing training is the number of available study materials. Fixed-wing students have access to untold number of books, online courses, DVDs, flash cards, maneuvers guides, and even audio training. Helicopter students have to make do with considerably fewer options. The book is well worth to read by a beginner pilot as the source of inspiration and self-confidence. 8. Fly the wing by Jim Webb. One more addition to the professional literature list! Written in an easy, conversational style, the book provides pilots with valuable tools and proven techniques for all flight operations and advanced aviation. US Army, J - WASHINGTON -- The Army is exploring improved mission systems configurations for both the Future Long-Range Assault Aircraft and Future Attack Reconnaissance Aircraft, as project officials engage with industry in a collaborative market research effort this week. This year, project managers launched a Mission Systems Optimization Study to evaluate . optimization studies are summarized. 2. Helicopter Model and Equations of Motion An augmented two-dimensional, point-mass model for the UHA helicopter, as schematically depicted in figure 3, is used for this series of trajectory optimization studies (refs. 10 and ). The governing equations are summarized below.
