Wind-tunnel tests have been made to assess the aerodynamic potential of an overwing installation for fan-jet engines on a typical modern transport aeroplane. Low-speed tests on a complete model with free-flow nacelles and tests at higher speed on a partial model incorporating a blown jet are described. It is concluded that the lift-dependent drag associated with such an installation would be significantly greater than that of a conventional underwing engine installation. (Author)
