![]() ![]() In an airplane or ‘Fixed-Wing’, the airflow over its airfoils are created by the entire aircraft moving at speed. The pilot then adjusts the pitch angle of the rotor blades to deflect air downwards for control. By moving them through the air the shape of each rotor blade creates a lower air pressure above it than below it. The turning rotor blades of a helicopter are its wings. How Does A Helicopter Produce Lift To Be Able To Hover?īefore we go jumping into how it gets off the ground we need to dive into some very basic aerodynamics that allows the helicopter to do its hovering party trick! To get an aircraft (Forget about Rockets) off the ground, an airfoil is used to generate Lift. How Does a Helicopter Stay Pointed in The Right Direction?įactors That Work Against Holding a Stable Hover How Does a Helicopter Stay In Position Over The Ground? How Does a Helicopter Get Off The Ground? This website follows the mantra: Everything Aviation – Simply Explained.Īrticle Contents: How Does a Helicopter Produce Lift? These will be simple explanations and a lot of the heavy technical aerodynamics are not covered. In this article, I not only want to tell you about the physics and aerodynamics of how a helicopter is able to hover but also what a pilot needs to do to get the aircraft into a hover and keep it there! If that sounds interesting then let’s go and get strapped in! It usually takes around 10 hours for a student to begin mastering the hover. When the amount of lift being produced equals the weight of the helicopter it will stay in a hover. A helicopter sitting in a stable hover is one of the worlds modern technological wonders and when I was learning to master it many, many years ago I can tell you that it made me sweat! Not only is it difficult to learn but the design and technology behind this marvel are truly staggering!Ī helicopter hovers by creating lift using its main rotor blades and deflecting air downwards to raise it off the ground. ![]()
