SWAG合集

Course structure

This five-day course is presented through lectures, tutorials, and workshops. The course will be delivered by expert Cranfield lecturers, and will also include guest lectures from high-profile industry and government specialists. Electronic copies of all the material presented will be made available to all delegates. The course will also include workshops with live demonstrations and 鈥渉ands-on鈥� application of state-of-the-art Cranfield tools for rotorcraft performance analysis, engine performance simulation, and UAM sizing and characterisation. A number of worked examples will be undertaken by the delegates. Active participation from the delegates is strongly encouraged. All delegates will receive a Certificate of Attendance upon completion of this course.
