Currently, by recovering the energy of the exhaust gases the advanced Internal Combustion Engines used in car racing have already managed to reach over 50% total effective efficiency (equal with fuel cell efficiency). However,
Well-known universal machine tool uses the non-accelerating propulsion design today. Excessive energy is never added to motor. The shift gearbox only provides needed torques /speeds by using the motor shaft standard highest torque and standard- idle speed.
In internal combustion engines the cam play a very important role and also takes huge impact on itself. The failure of cam is major issue which happens due to the follower, this failure is also known as the lobe failure.
Manned aircraft are quite heavy and cumbersome in some areas of aviation use. For example, aerial photography in cartography or forestry, spraying fertilizers or pesticides on medium-sized crop fields. And in these cases, unmanned aerial vehicles are a rational solution.
Drones give more secure, faster,
The present invention relates to Supplementary Seat for Public Transport with Retractable Hanging Support that provides additional sitting arrangement in available space for public transport such as buses and trains; without blocking the passengers to walk in and out of said public transport;
