Helicopters are notorious for showing downward thrust, prior to lifting off the ground, in a cloud of dust, flattened grass, or in people clutching their hats as they go to or from the helicopter.

Why don't helicopters spin around in the air?
Some helicopters feature a second rotor underneath the first rotor that counters the force applied to the body of the helicopter by applying thrust in the opposite direction of the main rotor. This stops the helicopter from spinning around. Others, instead of a second rotor underneath the first rotor have a back rotor that essentially does the same thing, which is provide a equal force to the first rotor preventing the helicopter from spinning =0
How do you use the word thrust in a sentence?

What is a sentence using thrust?

Which part of the airplane creates thrust?
The engine creates thrust.
How do helicopters get their thurst to move forwerd?
They tilt the hub down at front, this makes the thrust go backwards.
What is thrust diagram?
A thrust diagram is a diagram show the different bisected sections of a trust.
How does the function of the propeller differ in airplanes as opposed to helicopters?
Fixed wing aircraft use propellers for thrust only. A helicopter uses it's rotors for lift, thrust, and directional control. The tail rotor uses blade pitch to control yaw.
How are helicopters used in a medical setting?
Helicopters where used in several medical settings both Civil and Military. One of the most famous of these helicopters was the Bell H-13 Sioux most noted in the show M.A.S.H.
What is the ornithopter?
it is a simulated bird that is a machineIt's an aircraft that flies like a bird - by flapping its wings, as opposed to using rotors - as helicopters do - or fixed wings and engines providing thrust as aeroplanes do.
What force is used to fly a plane?
Thrust and lift are required to make a plane fly. A plane can use just lift if it is in the air already. The engines create thrust (if the aircraft has engines), and the wings create lift. Helicopters make lift by pushing air down, though.
Is jet-thrust forward propulsion available for helicopters?
No - Jet propulsion is not needed for the fact that it would suffer from retreating blade stall because of the lack of rotor rpms. They will have to figure out how to get better rpms prior to tackling jet propulsion. They have jet powered helicopters however they are still driven by the rotor system - not pushed by a jet.
