SUMMARY

The discussion focuses on calculating the additional lift required for a jet being refueled mid-air by a tanker. The fueling boom enters the aircraft at a 30-degree angle, with a fuel flow rate of 20 kg/s and a velocity of 30 m/s. To determine the additional lift, participants emphasize using the momentum and impulse principles rather than just force calculations. The correct approach involves analyzing the force components and applying the sine function to resolve the forces acting on the aircraft.

PREREQUISITES
  • Understanding of Newton's second law (F = ma)
  • Basic principles of momentum and impulse
  • Knowledge of vector resolution in physics
  • Familiarity with fluid dynamics concepts, specifically related to fuel density
NEXT STEPS

Homework Statement


A jet is refueled in mid-air by a tanker. The fueling boom enters the aircraft at an angle of 30 degrees from its flight path. The fuel flow rate is 20kg/s at a velocity of 30m/s with respect to the two aircrafts. The density of the fuel is 700kg/m^3
What is the additional lift needed to overcome the additional force?


Homework Equations


F= ma

The Attempt at a Solution


As Force is kg m/s^2, wouldn't the force be mass flow x velocity?
Then just do sin 30 to the force to get the y component.
But somehow I think I've got the wrong method...

Think about this in terms of momentum and impulse.
