In order to achieve greater operational efficiency a propulsive arrangement is provided in which a relatively large number of small propulsive assemblies 9; 31, 32, 33 are provided in aircraft structures in particular the wing 7; 30 . The assemblies 9; 31, 32, 33 comprise a flow path within which a compressor 39, 43, 47 is positioned to propel an air flow for propulsion. The compressors 39, 43, 47 are powered by electricity from an electricity generator 8 and possibly supplemented by solar cells or fuel cells or wing tip turbine generators 11 . The assemblies 9, 31, 32, 33 are small to allow easy removal for maintenance and repair.
