Tutorial: 1(Gas turbine theory)
Prob. 1: A peak-load generator is to be powered by a simple gas turbine with free power turbine
delivering 20 MW of shaft power. The following data are applicable:
Compressor pressure ratio
Tutorial: 2(Gas turbine theory)
Prob. 1: Calculate the specific thrust and thrust power of a turbojet engine flying with a speed of
222 m/s at an altitude of 1050 m where ambient temperature and pressure are 219K and 0.24 bar
Fuel Intake System
Fuel Intake System- Main Functions
Provides air and fuel to engine;
Mixes the air and fuel properly;
Controls the speed and power;
Fuel Injection in
S. I. Engines
The process of mixing proper amount of fuel with air
Merits and demerits of different engines:
(i) Turbojet engines are highly suitable for higher speeds, higher altitudes and long distance mainly
due to absence of propeller.
(ii) Power to weight ratio is very high compared to any ot
A spark can be created by applying a sufficiently high
voltage between two electrodes separated by a gap;
Theoretically, 1 MJ spark energy and few s time is
sufficient to initiate the combustion;
No spark occurs below a cert
