wheeling unit will allow the engine to drive the rotors but not allow the rotors to turn the engine. When the engine/s fail the main rotor will still have a considerable amount of inertia and will still want to turn under its own force and through the aerodynamic force of the air through which it is flying. The free wheeling unit is designed in such a way to allow the main rotor to now rotate of its own free will regardless of engine speed. This principle is the same reason that if you are in your car and

Reynolds number is the ratio of the inertia forces over the viscous ones and it dictates the transition process. We are interested in what caused this transition to occur and if there needs to be a critical value for this transition to happen. \ In aerodynamics many factors exist that contribute to the triggering of turbulence. In a three-dimensional boundary-layer on a swept wing, various instabilities are

This paper examines the physics involved in driving a golf ball off the tee. The objective of a drive is to achieve the greatest distance while leaving the golf ball in the middle of the fairway. Several factors will be considered in achieving the longest, and most accurate drive. The factors include calculating the velocity of the golf ball after the club and ball collide, the mass of the club head, launch angle, the shape of the club face, and finding the optimal golf ball. Intuition

When the next cycle started the night mist started to get burned off by the rising of the suns. Jovic looked at Meredith and decided then and there that she was the one he wanted to spend the rest of his life with. He rose slowly from the comfy moss that they had been lounging on all-night and offered her a hand to rise as well. She accepted the help gratefully and with the grace and beauty of a dancer she got up and stared deep into his eyes with admiration. He held her gaze and in a moment of

SAEINDIA SAE Student Convention Welcome to Aero-modeling using Paper Wings! Paper Airplane models for college students! 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

Fluid Mechanics 3-Aerofoil Lab Report Introduction This report aims to investigate the effect the angle of attack of an aerofoil has on the air flow around it. This was done by recording the lift and drag forces the aerofoil experienced when positioned at different angles of attack. The experimental lift force the aerofoil experienced when positioned at different angles of attack was then compared with theoretical values. An attempt was made to explain any discrepancies

Introduction When a viscous fluid flows along a fixed impermeable wall, or past the rigid surface of an immersed body, an essential condition is that a velocity at any point on the wall or other fixed surface is zero. To the extent to which the condition modifies the general character of the flow is dependent on the viscosity of the fluid. If a body has a streamlined shape and the fluid flowing over the body has a small viscosity that is not negligible, the modifying effect appears to be confined
