Question

From the information generated in Prob. 6.4 (from your previous Aero HW#1), calculate the maximum rate of climb for the single-engine light plane at sea level and at 12,000-ft altitude.

Answer 1

Answer:

R/C @ sea Level = 42.5 ft/s

R/C @ 12,000 ft = 24.6 ft/s

Explanation:

Given:

- From problem in 6.4:

         excess power @ sea Level = 232 hp

         excess power @ 12,000 ft = 134 hp

- Thrust delivered by the engine P = 3000 lb

Find:

Maximum rate of climb R/C @ sea Level and @12,000 ft altitude.

Solution:

- Maximum rate of climb (i.e no drag + maximum lift) @ sea level:

                  R/C = excess [email protected] level / Thrust delivered by engine P

                  R/C = 232 hp*(550) / 3000 = 42.5 ft / s

- Maximum rate of climb (i.e no drag + maximum lift) @ 12,000 ft:

                  R/C = excess [email protected] level / Thrust delivered by engine P

                  R/C = 134 hp*(550) / 3000 = 24.6 ft / s
