Q1/ For the following write either True or False and correct the false sentences. 1. Static stability is a necessary condition for an aircraft but not sufficient condition for dynamic stability. 2. The aerodynamic center (AC) is the point on the wing about which the coefficient of pitching moment is negative. 3. For static stability, the center of gravity must be in front of stick fixed neutral point NP (hNP> h). 4. If the center of gravity is at the aerodynamic center, the aircraft will therefore be statically unstable. 5. When the root is a real number and is negative e in characteristic equation of longitudinal motion, this motion is called divergence.

JUST DRAW THE SCHEMATIC DIAGRAM. NO NEED TO SOLVE. THANK YOU In Rizal province, one of its power plants has been thoroughly monitored for possible conversion into a wind power plant. A propeller wind turbine is to be used. Survey showed that Rizal Province at a height of 10 meters above the ground has a minimum wind speed of 7.1 miles per hour duringthe month of June and a maximum wind speed of 12.9 miles per hour during the month of January. The minimum temperature is at 75 degree Fahrenheit during the month of January and maximum temperature is at 89 degree Fahrenheit during the month of May. The existing power plant has an output of 54MW. For the proposed wind power, the power coefficient of turbine is 35% and the generator efficiency is 95%. Theimpeller diameter is assumed not to exceed 90m. Determine the following:a. Theoretical Wind Power Outputb. Electrical Power Outputc. Number of turbines to be installed
