Extract

In the past few years, many different VTOL experimental aircraft have been developed and tested in Europe, the USA and Russia and a great deal of experience has been gained.

Dornier's contribution in this field is the development and testing of the Do 31 VTOL jet transport (Fig. 1). A V/STOL aircraft concept had to be found, uniting the main advantages of relatively high flight speed, high pay-load capacity, operational flexibility, low maintenance requirements and great safety in case of engine failure. The Do 31 features these characteristics.
