Russia's Central Aerohydrodynamics Institute (TsAGI) displayed for the first time at the show two windtunnel models for a 750-seat airliner. Valery Sukhanov, TsAGI deputy director, flight control systems, says a blended wing body (BWB) model was built in the mid-1990s but this hybrid blended wing model was constructed last year. Both are 1:60 scale, representing aircraft with 600t maximum take-off weight. The BWB model was built to evaluate leading- and trailing-edge control surfaces, says Sukhanov.
