Possibilities of reducing the energy consumption of helicopters are discussed. The order of magnitude of the problem, i.e., the part helicopters play in total energy consumption, was established. The share of fuel consumption in comparison with total operational costs is dealt with. The energy balance of the helicopters Gazelle, Dauphin, and Puma is presented. Proposals for energy reduction are made which might lead to a 30% reduction due to engine improvements and 15% reduction resulting from aerodynamic improvements. Finally, a comparison with competitive aircraft, i.e., vertical takeoff aircraft, is made.
