SUMMARY

The discussion centers on calculating helicopter thrust during takeoff, specifically when fuel mass is included. It is established that the minimum thrust required at takeoff equals the weight of the helicopter. Participants clarify that while the mass of fuel is not directly useful for thrust calculations, knowing the horsepower (HP) required for takeoff allows for determining fuel consumption rates. The conversation emphasizes the importance of understanding the relationship between fuel use and thrust requirements.

PREREQUISITES
  • Understanding of helicopter weight and thrust dynamics
  • Knowledge of horsepower (HP) calculations for helicopter engines
  • Familiarity with fuel consumption metrics in aviation
  • Basic principles of physics related to force and mass
NEXT STEPS
  • Research "Helicopter thrust-to-weight ratio" for performance analysis
  • Learn about "Helicopter engine horsepower requirements" for takeoff
  • Explore "Aviation fuel consumption calculations" for efficiency assessments
  • Study "Physics of lift and thrust in rotorcraft" for foundational understanding
USEFUL FOR

Aerospace engineers, helicopter pilots, and aviation students interested in understanding thrust calculations and fuel dynamics during helicopter takeoff.

can anyone help me out to calculate the thrust when helicopter takes off with mass of fuel?
 
Engineering news on Phys.org
Calculate how? From what starting information? The minimum thrust required at takeoff is the weight of the helicopter.

i want to know how to calculate if mass of fuel is given?
 
Fuel use will be determined by the engine.

If you know the HP required for take off, you can work the fuel use from that.

Mass of fuel (unless you mean use rate) is not a piece of information that is useful in determining the thrust of a helicopter.
 
Oh I see, he knows how much fuel is used and wants to work out thrust from that.

I agree with you russ, I thought he meant how much fuel is used during take off.
