The CHAIRMAN, in introducing the Author, said that Mr HOOPER was presenting to the Association its first lecture on the subject of wind tunnel testing of helicopter models Mr Hooper had a long experience of wind tunnel techniques and had also been able to apply some of these techniques recently in investigating the aerodynamic features of one of the latest rotary-wing prototypes—namely, the Rotodyne
Mr Hooper had been engaged on aerodynamic testing for many years, and next year would be his thirtieth year with the Fairey Aviation Company He had investigated a wide range of subjects such as the aerodynamics of sails for application to racing yachts and had also been concerned with the attainment of flight speeds greater than Mach 1 Thus it was not surprising that he had taken the wind tunnel testing of helicopter models in his stride and was tonight able to give an authoritative assessment of the value of this work
