How do helecopter blades spin so fast?
Helicopter blades operate from a transmission or gearbox immediately under the blades. They have to spin fast to give the helicopter lift. Once they are in the air the blades twist slightly to give forward motion.
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.
