- What is the lift? ____________
- Change the velocity (airspeed) as shown in the following table
and record the associated lift for each velocity to complete the
table.
Velocity (km/h) Lift (Newtons) 50 100 150 200 250 300 400 __Table 1__ - Construct a graph of velocity's effect on lift with an
Independent Variable(X) of velocity and a Dependent Variable(Y) of
lift. Label each axis correctly to include units.
- What is the shape of the curve formed by this relationship?
- Write the equation for this relationship.
- What is the value of the constant in this equation for this
set of conditions? C = _____________________________
- Interpolate the lift for a velocity of 350 km./hr. What is the
lift? _____________
- Extrapolate the lift for a velocity of 500 km./hr. What is the
lift? _____________
- Based on the relationship between lift and velocity, how would
you increase the lift on a wing?
- Set the initial conditions provided in Problem 1 above and
assume: g = 9.8 m./sec.
^{2 }at this elevation; total weight of airplane, cargo, and fuel = 5000 kg.; weight of airplane = 3000 kg. ; weight of cargo and fuel = 2000 kg. Use the equation for lift that you generated in Problem 5 to answer these questions:- What is the lift in Newtons required to
maintain altitude in these conditions?
