The airplane is equipped with two jet engines with 40,298 N of static thrust each at sea level. a. Calculate and plot the power-required curve at sea level.

Consider an airplane patterned after the Fairchild Republic A-1 0, a twin-jet attack aircraft. The airplane has the following characteristics: wing area = 47m2, aspect ratio = 6.5, Oswald efficiency factor = 0.87, weight = 103, 047N, and zero-lift drag coefficient = 0.032. The airplane is equipped with two jet engines with 40,298 N of static thrust each at sea level. a. Calculate and plot the power-required curve at sea level. b. Calculate the maximum velocity at sea level. c. Calculate and plot the power-required curve at 5-km altitude. d. Calculate the maximum velocity at 5-km altitude. {Assume the engine thrust varies directly with free-stream density.)

The wing is at an angle of attack of 5° in an airflow velocity of 100 at standard sea-level conditions. Calculate the lift, drag, and moment about the quarter-chord per unit span.

1. By the method of dimensional analysis, derive the expression M = q~ Sec., for the aerodynamic moment on an airfoil, where the chord and c,. is the moment coefficient. 2. Consider an infinite wing with a NACA 1412 airfoil section and a chord length of 3 ft. The wing is at an angle of attack of 5° in an airflow velocity of 100 at standard sea-level conditions. Calculate the lift, drag, and moment about the quarter-chord per unit span.

.Describe the implications for leadership and a leader’s relationship with followers.

You have been invited by the human resources manager of a medium-sized company to prepare a “report” on “In Groups and Out Groups.” The report will be distributed to departmental VPs and directors.

In the report you should:

1.Introduce the concepts of In and Out groups.

2.Describe a situation where you (or someone you know) were a member of the “In group” and another situation where you (or someone you know) were a member of the “Out group.” This should be an example from your own business experience.

3.Analyze and explain the major differences between the two situations.

4.Explain how having an in-group and an out-group affected the groups and the organization.

5.To what extent was membership in either the in-group or the out-group based on task related performance factors? What non-task related factors entered into the decision?

6.Describe the implications for leadership and a leader’s relationship with followers.

Use the Library or other Web resources to support your argument. Be sure to cite your sources using APA Style 6th edition guidelines.
