The technology that went into the first helicopters was nothing special. It just took special skills to design the controls for the main rotor blades.
I'm familiar with the invention of the first Bell helicopter that was begun in 1943. Arthur Young designed a model helicopter that he could fly by remote control. Since radio was new, his model had a long electrical cable that was attached to a "trapeze" under the model that transmitted the inputs.
Arthur Young lead a team of engineers to design a full-scale flying prototype. One of the problems they had in the construction was the transmission. The transmission required a gear reduction of 1:47, as I recall. The engineers couldn't do it. So they disassembled Young's model and drew up the pieces to full scale to make the planetary gear transmission that drove the main rotor.
After that, all it took was a lot of testing and adjusting the controls to make make the rotor stable but flyable. They added a stabilizer bar that helped keep the rotor tracking smoothly---which was still in the design of the Bell Model 47.
For the helicopter body to be in balance and direction to steer the helicopter.

Science and Technology are linked, when the first caveman picked up a bone to use as a club science was the method with which he used his logic to create technology (the club). one could argue that science is necessary to invent technology and therefore must have come first.
An engineer, Igor Sikorski, invented the helicopter.
No African American invented the helicopter. The first practical helicopter was invented by Igor Sikorski, a Russian American.
Yes.

Rotary-Lift Aircraft
A chopper is a type of motorcycle, machine gun, or helicopter.
Car, Airplane, train, bus, subway, and helicopter are all examples of transportation technology.
Yes, it's necessary for communication. Even in luxury helicopters it can be quite noisy at times
He drew some helicopter like machine graphics. He had the insight, just not the available technology to build one.
Not sure whether you mean the Helicopter or Web Server software... For the helicopter, the detailed specifications of it's computer are classified, but it will be something that is quite powerful.
An air ambulance helicopter is generally the same as an ordinary helicopter except for the fact that it is equipped to save lives just as a regular ambulance is equipped. Air ambulance helicopters must have the medical supplies necessary to save lives.
A helicopter is controlled with a joystick, which usually lies between the feet. Power is usually set at one point in flight and left until landing is necessary.

A home phone is not necessary and a waste of money with cell phone technology.
