Beginner's Guide to Propulsion
Forces in a Climb -
Worksheet
- Assuming the angle of ascent is a constant, find the
angle the plane must use to achieve this height at this distance
--to the nearest degree. Make a diagram and explain how you
arrived at your answer.
Note: Don't forget to change radians to degrees.
- We are going to use this information to find vertical and
horizontal net forces.
a. Find the thrust for a Boeing 737-200 airplane.
Thrust =____________
b. What is the take off weight of the plane? Change this weight to
Newtons.
Weight in lbs. = ___________ Weight in Newtons
=___________
c. Use the first equation on the Forces
In A Climb page to find vertical net force. Use 519,154 N as
the lift and 25,957 N as the drag.
Show the original equation and then show the substitutions with
your answer. Label answer with correct units.
d. Use the second equation to find the horizontal net force; use
lift and drag from part c above.
Show the original equation and then show the substitutions with
your answer. Label answer with correct units.
- Divide your net force from 2c and 2d by the weight of the
airplane to get the vertical and horizontal acceleration in "g's"
(ratioed to gravitational acceleration).
a. Vertical acceleration = _________________g's
b. Horizontal acceleration = _______________g's
