- This is believed to be the first published example of vortex generator optimisation for buffet minimisation using high fidelity simulation. Successfully eliminated all flow separation at high-lift conditions without compromising drag. Methods are used at Leonardo Helicopters and the results have since been validated and published by Leonardo (Nigel Scrase and David Tring contacts). Initial technology resulted in a £500K ATI/AgustaWestlands grant, part of £2.7M ATI HyperTilt grant, and the methods presented here were the UoB outputs from that grant. Subsequently led to related £3M EPSRC grant (with Glasgow, Manchester, Southampton, Cranfield) EP/S010378/1, aimed at cutting-edge rotorcraft simulation and optimisation.
