Theory of Longitudinal Static Stability Stick Fixed Stability (tailless aircraft) An aircraft that has elevons (combined ailerons and elevators) e.g.‚ Concorde is governed by slightly different equations. The effect of the tab angle is usually ignored as most tailless aircraft have powered controls and so no tabs. The lift equation therefore becomes Moments about the cg give us: For TRIM‚ the elevon angle to trim is [pic] For STABILITY it is clear that the aerodynamic

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

Introductory Information What we want to find out is that does the angle of blades on a wind turbine affects how much energy is going to be produced. The reason we feel that we that this would be a good topic to research is because wind turbines are starting to become more and more popular. Wind turbines have been used for many years for little and big things? They have been used on small farms and recently they have also been used on many large wind farms. They can vary in size depending on

Today I will be talking about paper airplanes and what type of paper airplane flies the farthest also which one stays aloft the longest. Some of the topics I plan to discuss involve aerodynamics‚ drag‚ shape‚ size‚ forces‚ and gravity. Drag is the force of flight that pushes an airplane opposite to the direction it is moving. The biggest types of drag are friction‚ when air rubs against the surface‚ and difference in air pressure. Think of a drag like swimming treading through the water you can’t

Activity 1: X-Gliders Lesson Objective: Campers will learn about the forces of flight‚ weight and balance when they construct a glider. As they improve the design of their glider they will understand that a variable is a single change in the engineering. Set-Up: Each student will need two foam trays‚ a plastic knife and an x-glider template. Materials for weight and balance can be distributed at a communal table. Demo and discussion: Start off the lesson by asking your campers‚ “What are gliders

Abstract The problem discussed in this report is how lift is truly generated on an aerofoil and also explaining the misconceptions of lift and why they are not correct. Further topics discussed are the Lift is a force that directly opposes the weight of an aircraft and holds the object in air. Since lift is a result of the thrust or motion of the aircraft it is therefore a force (vector) because it has a magnitude and a direction. But lift cannot be achieved without thrust. This is the mechanical

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.

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

Title of Experiment: Pressure distribution on an aerofoil Aim: The aim of this experiment is to examine the pressure distribution on an aerofoil and its variation with incidence. Introduction: An aerofoil is the two-dimensional cross section of a wing‚ tail or helicopter rotor blade. The lift and pitching moment on an aerofoil is determined by the pressure distribution on it. The pressure distribution changes with the angle of incidence. Understanding the behaviour of aerofoils requires some
