both are limited by maximum piston acceleration , which occurs at higher revs in shorter stroke engines

Why can't you attach a jet engine to a helicopter with similar results?
Question is not very clear. Most modern Helicopters are powered by turbo-jet engines that drive a transmission gearbox to turn the rotor blades. Jet engines have been attached to the tips of the main rotor blades. This design was used to turn the blades faster and have a smaller engine and gearbox. The forward velocity of a typical helicopter is limited by the tip speed of the rotor blades. The tip speed of the advancing blade is the sum of the airspeed of the helicopter and the speed of the blade. That is why helicopters are limited to ~150mph. If a jet engine was installed to push it faster, then either -A- the rotor blade would hit the sound barrier and become unstable or -B- the rotor blade would have to be stopped and the helicopter would have to fly using lift from a wing.
What are the advantages of a gas engine?
gas engines go faster that the batter powered engines and last longer (dont have to charge gas)
Can NOS be used on a diesel engine?
Diesel engines use propane to go faster, only gas engines use NOS
Is a helicopter faster than an airplane?
No. A helicopter is not faster than an airplane. A helicopter could fly at about 400-650 kph. But a plane could fly much faster than that.
Can a helicopter fly as fast as a plane?
A fast aeroplane will be faster than any helicopter, but a fast helicopter can be faster than a slow aeroplane.
How has the victor lawnmower improved life?
faster and easier.
What is faster jet or helicopter?
Jets are much faster .
What oil should you use for a small lawnmower?
Look in the owners manual if you have it and see what the rating on the oil should be. I think most air cooled engines require a SG or SJ rating but I'm not sure. Air cooled engines run at higher temp than water cooled engines so, although automotive oils will work, if you're looking for long term service the proper rating will be best. Another thing you should do is run the engine at full throttle to keep the fan turning faster to cool the engine.
What is the difference between petrol and diesel engines?
diesel engines doesn't use spark plug but uses heater plug.petrol engines produces more torque than petrol engines but petrol engines produces more acceleration than diesel engines.petrol engine is faster to be heated than diesel engine.
Why does NASCAR use pushrod engines?
It helps keep speeds down. A pushrod engine can only turn so many RPMs before the engine isn't able to properly control the valve train. It's called "float." When the valves float, you lose power. An overhead-cam engine directly controls the valves, so engines set up thusly can turn far faster than pushrod engines. And all else equal, the faster your engine turns, the faster your car goes.
What is faster a plane or a helicopter?
plane
Are cars with bigger engines faster than smaller engine cars?
Yes, they usually are, but it can differ from car to car. For example, a Chevy Suburban is faster than a smart car because there are more pistons in the engine, creating more torque and speed, therefore making the car go faster. On the other hand, however, a motorcycle is faster than most cars, yet they have smaller engines.
