can anyone help me out to calculate the thrust when helicopter takes off with mass of fuel?
russ_watters said:Calculate how? From what starting information? The minimum thrust required at takeoff is the weight of the helicopter.
Mass of fuel (unless you mean use rate) is not a piece of information that is useful in determining the thrust of a helicopter.astro2cosmos said:i want to know how to calculate if mass of fuel is given?
Helicopter thrust is calculated by combining the mass of the helicopter and fuel with the velocity of the rotating blades. This creates a force that propels the helicopter upwards.
The main factors that affect helicopter thrust are the weight of the helicopter and fuel, the angle of the blades, and the air density. Changes in these factors can affect the amount of thrust produced and the overall performance of the helicopter.
Fuel mass is included in helicopter thrust calculation by adding its weight to the weight of the helicopter. The more fuel that is present, the greater the weight and therefore the greater the thrust needed to lift the helicopter.
Fuel consumption can greatly affect helicopter thrust as it directly affects the weight of the helicopter. As fuel is used up, the weight of the helicopter decreases, requiring less thrust to maintain flight. However, if too much fuel is consumed, the weight can drop below the minimum required for stable flight.
The most common units used for helicopter thrust calculation are pounds (lbs) for weight, feet per minute (ft/min) for velocity, and cubic inches (in^3) for fuel volume. However, different countries and organizations may use different units, so conversion may be necessary for accurate calculation.
