Rotocopters work by spinning rotor blades to generate lift. The weight of the rotocopter is supported by this lift force, which must be greater than the weight for the rotocopter to stay airborne. Drag is generated as the rotocopter moves through the air, which must be overcome by thrust generated by the rotor blades to maintain forward motion.

What is sustained flight?
Sustained flight is the ability of an aircraft to remain in the air for an extended period without losing altitude. It requires a balance between lift, thrust, weight, and drag to keep the aircraft airborne. Achieving sustained flight is essential for aircraft to travel long distances efficiently.
How do aircraft fly?
There is two categories of aircrafts, the aerostats (lighter than air) and the aerodynes (heavier than air). -Aerostat: the aerostat uses buoyance to float in the air in much the same way that ships float on the water.They are characterized by one or more large gasbags or canopies, filled with a relatively low density gas such as Helium, Hydrogen, or Hot air which is lighter than the surroundind air. When the weight of this is added to the weight of the aircraft structure, it added up to the same weight as the air that the craft displaces. -Aerodyne: To fly it must move forwards through the air ,this movement of air over the aerofoil shape deflects air downward to create an equal opposite upward force, called lift, according to the Newton's third law of motion. Aerodyne flight: The best method to answer this question is thru the use of the lift formula: L= (1/2p) (V2) (S) (CL) 1/2p (pronounced rho) is basically the density of the air. Cool dense air provides better pressure in creating lift. V2 is the velocity of the airfoil flowing thru the air. Higher velocity creates more lift except when reaching velocities that exceed the sound barrier disrupting laminar flow over the airfoil. S is the surface area of the airfoil. A larger surface area creates more lift. It may also create more weight which would increase the need for more lift. CL is the coefficient of lift. Without getting to complicated, this is basically the efficiency of the airfoil design at an angle of attack. Angle of attack is essentially the angle between the chord line of the airfoil and air flow direction. When air flows over the airfoil, the design of the foil seperates the airflow into an area of low pressure over the camber of the airfoil, and an area of high pressure below it. Obviously the difference between the two areas will cause the movement of the airfoil in the direction of low pressure thus creating lift. Their are four forces at work in the creation of lift: Lift - Explained above Thrust - The force required to move the craft forward to create velocity of airflow. Drag - The force created from the creation of lift and thrust. Parasitic, Induced, and Profile drag are the different types of drag working against lift. Weight / Gravity - What must be overcome by lift.
Can you lift your own weight?
it is proven that you can lift your weight or more And you can push nearly 2 times more with your legs!
What is lift thickness?
Lift thickness refers to the measurement of the distance between the upper and lower surfaces of an airfoil, specifically at its thickest point. It plays a crucial role in determining the aerodynamic characteristics of the airfoil, including its lift and drag properties. A thicker airfoil can generate more lift at lower speeds but may also increase drag. The optimal lift thickness varies based on the intended application, such as gliders versus high-speed aircraft.
Where does dynamic equilibrium take place?
Dynamic equilibrium takes place in a closed system where the rate of the forward reaction is equal to the rate of the reverse reaction. This means that the concentrations of reactants and products remain constant over time, even though the reactions continue to occur. Examples include chemical reactions, such as the Haber process for ammonia production.
What are the four forces that act on an airplane in flight?
Lift, weight, thrust and drag.
What is the relationship of lift drag thrust and weight when the airplane is in straight-and-level flight?
Lift equals weight and thrust equals drag.
What are the forces on an airplane?
There are four forces that act on an airplane that keeps it at a level altitude. Thrust, drag, weight, and lift determine whether a pilot flies at a level altitude.
What is the relationship between the 4 forces of flight?
Lift is opposite of weight Thrust is opposite drag. When lift >weight plane climbs. If lift < weight you best find a place to land. If thrust> drag you accelerate. If drag>thrust you slow down. High and fast are your friends. Low and slow are out to kill you.

What are the forces of a helicopter?
Thrust, Drag, Lift, Weight (Gravity).
What are the forces of a plane flying at a steady height?
The forces acting on a plane flying at a steady height are lift, weight, thrust, and drag. Lift is generated by the wings and opposes the weight of the aircraft. Thrust is produced by the engines and counters drag, which is caused by air resistance. At a steady height, these forces are balanced.
