Controlled Assessment – Helicopters You need to research information (using the internet) that includes answers for the following questions: 1. How the turning rotor makes a helicopter move upwards 2. How the rotor is made to turn in a helicopter and in an autogyro 3. How autorotation is used to help land a helicopter safely if the engine fails 4. Why a helicopter; falling during autorotation‚ could reach a terminal speed without the pilot changing any controls 5. The effect of the weight of

Enjoy Learn and align with Curriculum September 2008 Paper Wings Guidelines This may look ridiculous and appear to be a child’s play. As you use the kit and build your first plane‚ you will realize that it is not all that simple. Soon you will learn to make the plane to fly and discover the joy of flying. In the process you will learn the nuances of flying intuitively. This
Premium Wing Lift Aerodynamics
1.On a swept wing aircraft if both wing tip sections lose lift simultaneously the aircraft will a) roll b) pitch nose up c) pitch nose down 2. Lift on a delta wing aircraft a) increases with an increased angle of incidence (angle of attack) b) decreases with an increase in angle of incidence (angle of attack c) does not change with a change in angle of incidence (angle of attack 3. On a straight wing aircraft‚ stall commences at the a) root on a high thickness ratio wing b) tip on
