Università Roma Tre

PART 1: ELEMENTS OF GAS_DYNAMICS
Introductory concepts; isoentropic compressible flows and normal shock waves; design of gas-dynamic systems. Fanno and Rayleigh flows. Oblique shocks and odograph plane. Prandtlt-Meyer expansion. Compressible potential flows, linear theory and supersonic thin qirfoil. Characteristic method (in 2D and steady).
PART 2: AICRAFT PROPULSIVE SYSTEMS
Introductory concepts and classification. Performance parameters. Definition of thrust and power. Definition of efficiencies. Turbo-gas cycle (real and ideal). Simple turbojet; turbofan; ramjet; turboprop. Propellers and blade element theory. Nozzles and diffusera (sub- and super-sonic). Elements of combustion.
Several practical exercises are carried out during the course.

Notes distributed by the teacher.
