FMA-011
Thermodynamics, propellants, turbomachines - 2019

Air-intakes, nozzles and after-bodies

OBJECTIVE :

The aim of this course is to provide participants fundamental bases allowing a better understanding of the various aspects involved in the design of propulsive nacelles. This implies the knowledge of analytical and computational methods, as well as of test facilities and corresponding measuring techniques.

COURSE DURATION AND TIMETABLE :

The course, the duration of which if 5 days (30 hours), includes 20 lectures and training exercise sessions of 1h30.

GENERAL APPROACH :

The course is based on the physical description of phenomena and presentation of practical predictive methods.

Conferences are complemented by application exercises.

A large number of real configurations are analyzed. Information about recent experimental techniques is also provided.

Courses FMA 06 (Initiation to aerodynamics) and FMA 013 (Viscous and turbulent flows) constitute a good preparation to the present course.

PREREQUISITE :

Level: Upgrading

This course is best suited for engineers and technicians desiring to consolidate their expertise in the field of applied aerodynamics.

COURSE DIRECTOR(S) :
