The friction of rubbing up and down causes the sparks to ignite and to spill everywhere.
The forward propulsion of an aircraft is called thrust.The thrust is given by the engines.
The thrust is an airplane is provided by the engines.
the engines of a flying thing E.G rocet engines
Thrust is the main propulsion medium. The jet engines produce the thrust (the force forward) the air moves across the top of the wings creating a vacuum which in effect hold the aircraft in flight. The greater the engines are worked the greater the thrust and therefore speed.
the engines
The propulsion provided by the engines.
it depends on the airplane's chosen engines. engines can range from a few thousand lbs of thrust to around 50,000 lbs of thrust. most commercial jets pull out around 30-45,000 lbs of thrust
Well, thrust is propel something forward. There are 4 different types of thrust, that is ....a)Propeller b)Jet engine c)Rocket engines d)ramjet engines... Check this website out to know more about thrust =http://www.boeing.com/companyoffices/aboutus/community/fof_thrust.html
Thrust
The jet engines
Most biplanes had radial engines driving a propeller, this created thrust when it rotated.
For thrust. Engines are used to overcome the drag of the airplane.
