Thrust To Weight Ratio Given By Min Drag Coefficient Calculator

The Thrust-to-Weight Ratio is the engine thrust divided by the weight of an aircraft, calculated at the airspeed corresponding to the minimum drag coefficient, this condition is crucial for optimizing the efficiency of an aircraft, as it signifies the point where the aerodynamic drag is minimized, allowing for optimal performance and fuel efficiency. The thrust-to-weight ratio at this specific condition is a key parameter in assessing an aircraft’s ability to climb, accelerate, or maintain steady flight. The formula to calculate T/W as follows:

Where:

  • represents the thrust-to-weight ratio.
  • is the minimum drag coefficient.
  • denotes the wing loading in Pa.
  • is a Lift Induced Drag constant.
  • is the the load factor.
  • represents dynamic pressure in Pa.
