MAE130B Concept/Question/Comments Film: Channel Flow of a Compressible Fluid Due Date: March 15‚ 2013 Concept 1: Choking Choking occurs when the Mach number at the throat of a channel flow is equal to one. Conceptually choking is the phenomena where the flow in a channel transitions to sonic flow. Due to the conditions of choking‚ the velocity‚ density‚ and pressure can increase or decrease continuously through a sonic throat‚ and the flow does not need to be symmetrical. Another notable phenomena

Materials: Balsa wood‚ ruler‚ protractor‚ balsa wood glue‚ razors‚ rubber band‚ paper‚ washers (used for nose weight)‚ and writing utensils. Distance or Duration? The very first decision I have to make before I explain my design of the balsa wood plane is to decide whether I should try to build a plane that competes for distance or for duration. After thinking about what to pick‚ I decided out of the two‚ the better one to compete for would be duration. The reason why duration is the better option

HOW TO BUILD YOUR PAPER AIRPLANE! THE “DART” Make sure the location of the star on your paper plane print out matches the location of the star in the directions below! 1. Pattern side down‚ fold paper in half‚ then unfold. 2. Fold both top corners in to center crease. 3. Fold both sides in again so the corners meet at the middle crease. 4. Fold plane in half. 5. Fold down both wings so the two top corners meet the bottom edge of the plane. 6. Unfold wings so they lie horizontal when

Newton’s First Law of Motion explains that objects in a state of uniform motion tends to remain in rest unless an external force is applied to it. Galileo’s concept of inertia is termed “Law of Inertia”. Law of Inertia‚ an object in motion will continue in the same motion unless acted by an outside force. Aircraft in flight is an example of First Law of Motion‚ four forces on an aircraft; lift‚ weight‚ thrust‚ and a drag. Consider the motion of an aircraft at constant altitude‚ we can neglect the

Questions: 1. How does air resistance affect the falling of a parachute? Air resistance affects the falling of a parachute because the resistance in the air molecules slow down the falling of the parachute. If there were no air resistance then the gravity would pull the parachute toward earth and it will drop very fast. 2. What aspects of a parachute affect the amount of air resistance generated? Length‚ mass‚ and materials are some of the aspects that affect the amount of

BOUNDARY LAYER THEORY INTRODUCTION The concept of boundary layer was 1st introduced by L.Prandtl in 1904. Figure 7-1. Viscous flow around airfoil A structure having a shape that provides lift‚ propulsion‚ stability‚ or directional control in a flying object. Boundary layer is formed whenever there is a relative motion between the boundary and the fluid. Boundary layer thickness: 1. Standard thickness - signified by ‚” it is define as the distance from the boundary layer

The Delta Wing Is a unique type of wing platform that has been part of the aviation engineering industry for many years. The Delta Wing has been used for numerous reasons. When working with delta wings‚ engineers must know that the design has both advantages and disadvantages. Through out the assignment‚ I will be using the research I have collected to identify the range of basic scientific principles and techniques relevant to the Delta Wing design and the history behind the Delta Wing.
