TECHNICAL ADVANCES IN AIR BREATHINGPROPULSION

AIR BREATHING PROPULSION


Propulsive device

 generates the net thrust to overcome inertia and gains speed

Air breathing propulsive device

 uses oxygen in air to burn fuel and to generate thrust
 limited to dense atmosphere up to a height of about 100 km
 only jet propulsion presented in this seminars

Turbojet
 Engines with rotating machinery
 Used by most civil and military aircrafts operating at subsonic
speeds ( Mach <1 )
 General Electric , Pratt & Whitney , Rolls Royce
Ramjet
 Engines without rotating machinery
 Used for supersonic missiles up to Mach 5
 Soviet SA-6 ,British Sea Dart , French Snecma M-88
Scramjet
 Engines devoid of rotating machinery
 Will be used for hypersonic missiles above Mach 5
 Nasa X-43 , British HOTOL , German Sanger
TURBOJET


 Air sucked in through the inlet diffuser
 Compressed and used to burn the fuel in the combustor
 Combustion products used to drive the turbine
 Exhaust through the nozzle to generate jet propulsion
