Hybrid Laminar Flow Demonstration on Aircraft

Objective



BE95-1084 Hybrid Laminar Flow Demonstration on Aircraft - HYLDA Energy costs of air transport will rise appreciably over the next decade due to environmental concerns. This indicates that features of aircraft and engine design which reduce fuel consumption per passenger kilometer will be of great importance. Laminar Flow Technology has the largest fuel saving potential of all presently considered aerodynamic technologies. The EC has supported work in this field from 1989 onwards (ELFIN European Laminar Flow Investigation, and LARA -Laminar Flow Research Action). Our US competitors have conducted several Hybrid Laminar Flow (HLF) flight tests from as early as 1983; Boeing has applied for a number of crucial patents already. As a first step towards a European high Reynolds number in-flight demonstration of Hybrid Laminar Flow, the feasibility of a wing glove (Task A) and a Hybrid Laminar Flow nacelle (Task B) will be investigated in a three year project. Flight tests with an A320 HLF Fin (Task C) will be conducted to investigate operational aspects as de-icing of suction surfaces and the influence of surface roughness.

Tasks A, B and C are supported by suction surface design and data analysis activities. The work performed in HYLDA is an integral part of a strategic long-term industrial approach the develop Hybrid Laminar Flow technology for large transport aircraft (Re>30 millions, Ma>0.8). Detailed cross-functional strategy development and multi-disciplinary design work will be performed in order to create a sound basis for a go ahead decision. Wing and nacelle work are performed in the programme to make maximum use of synergy effects. The major achievements expected in HYLDA is the recommendation either for or against flight tests. If a flight test recommendation is given in HYLDA the proposed flight test will be performed within an European collaborative programme outside of HYLDA.
