Abstract [en]

The main performance characteristics of a heli- copter is its fuel consumption. This paper re- ports the current state in an ongoing project seeking a fast and approximative implementa- tion of mathematical models for helicopter per- formance predictions, primarily in terms of fuel consumption. The model is limited to a subset of the normal operation modes, only including hover, climb and forward. Also, the focus is on smaller rotors, i.e. sub-scale rotors in the range of 1.5m to 4.0m in diameter as used in unmanned airborne vehicles (VTOL-UAV). The presented work consists of three parts; the heli- copter performance mathematical model and the numerical optimization method used for dealing with its implicit nature, the approximation grid scheme and the simulation of flight paths. The overall objective of the project is to establish an computational efficient approximative model us- able for onboard condition monitoring of the he- licopter performance and fuel consumption.
