why is a motorcycle more aerodynamically affected than a truck??, I have been lead to believe it is because of the lower density, is that true?? and how can i justify it?? Thanks

Hello experts, I hope you can help me with the following problem. There is one huge pipe (diameter about 3 meters). In that pipe there is a flow of mixture ash and air. That mixture is very hot (about 300 °C) and abrasive. I need to measure temperature of that mixture. I placed thermocouple...

The wind turbine I pass everday seems to have its blades almost flat to the wind. So, I want to make sure I understand exactly what the wind turbine is doing, and if I have the airfoil components right - see my diagram. It seems to me that, as the angle of attack is increased, the resultant...

I'm just beginning to study aerodynamics, and i was wondering if anyone could list the topics, fields, and types of math that are used in textbooks, research papers, journals etc. that one would read when studying aerodynamics?

Hi, I have some questions about helicopter aerodynamics. I have been searching the web (and this forum) up and down but I could not find the answer. Maybe you can help. I want to calculate the cruise and maximum speeds of a helicopter given the weight, motor power, height (assuming pressure...

Can some1 tell me r there any short term courses available on aerodynamics or can anybody refer me a good book...

Hi i am new in this forum, and i have a paper on aerodynamics, which is a bit general... Basically the paper is on how to affect lift and drag in automotives... could you help me with this... thanks

Hi, I'm currently doing a research study on the effect of the presence of a rear car spoiler on the lift of a vehicle at low speeds As far as my understanding, with an increase in air velocity, there should be an increase in lift on the car. My trials however show that with an increase in air...

I'm no fluid dynamics/aerodynamics expert, but the uncovered headlights on the Maserati MC12 and the Ferrari FXX just irk me... it just feels like having a plastic cover over them would be a better aerodynamic solution if not a cosmetic improvement. However the fact they're not there in the...

I've been thinking about the wind turbine (horizontal turbine - like an airplane propellor.) that I pass on the way downtown and I'm realizing I've been taking for granted how it works. Seems to me it's exactly opposite of an airplane wing. Rather than forward speed generating lift, you have...

My school doesn't offer any courses on aerodynamics, except a graduate level engineering course. I was hoping someone could recommend a good textbook for self study.

Hey here is a quick question. I have a question on an assignment that is asking me to define lift in an aircraft (done) and its relationship to the aircraft's centre of mass. I'm unsure how to do that second bit as lift acts through the centre of pressure...not the centre of mass (also known as...

Hey, first post. I've been searching around everywhere but I am yet to come up with an an equation or theorem that relateds altitude to speed and the forces that act on a plane (thrust, weight etc). I am perhaps assuming that, in at least this question, the altitude of the plane doesn't affect...

Here's the problem: We are ascending in an elevator at sea level. Our eardrums feel a 1 percent decrease in pressure per minute. Calculate the upward speed of the elevator. My solution: *I am using the equation p1/p0 = (T1/T0)^(-g/aR), where p1 and p0 are pressure at point 1 and point 0...

I'm looking to do something in the field of aerodynamics and/ or fluid dynamics...I want to go into aeronautical engineering when I do my undergrad, I am posting for a essay tittle which proposes certain interesting problems in those two fields. The essay should be 4000 words long and the more...

Hi, can anyone please tell me any good book on the subject, even any research paper will do, we are actually doing summer project in which we are estimating the drag coefficient on the bluff body like train Coach, using commercial softwares like Fluent n Gambit.Please if anyone has the info...

Hi there! I'm doing research for computer science and I have to simulate wind movement. Obviously, I need to know stuff about wind movement. I've tried several books and they haven't given me what I want. Most books have the whole "how do we make this airplane go fast" thing going on...

hey guys..totally confused on this question! How is the goal of safety at odds with aerodynamic efficiency? OK...the way I am interperting is as. How does the goal of safety interefere with the factor, or progress, of Aerodynamic Efficiency...any help on the answer and where to get started?

How do you understand Aerodynamics?

American Institute of Aeronautics and Astronautics (AIAA - www.aiaa.org ) Good site for those who are seriously interested in basics of aerospace propulsion, rockets (missiles), and mission design Some titles you might find interesting (as of Sep 18, 2005 and subject to change)...

hi, i am taking graduate course in aerodynamics and the professor has not provided class with text. He had recommended "Aircraft Design" by Raymer, and also a book by Anderson. Anyone know other good texts on Aerodynamics, if so please let me know. Thank you kindly Manu

I have been toying with the idea of modding my road bike (pedal) for increased aerodynamicy; for starters of adding a small fiberglass shell on the front to channel the air around my legs and lower bike frame possibly eventually adding a shell to control the flow around my shoulders more does...

Which book would you recommend for introduction to aerodynamics? One which is mathematically rigorous as well as comprehensive?

Hi! I've written a simple software to calculate projectile trajectories when air resistane can't be neglected. I'm planning to test the software with a light ball and a cannon. My model simply say F = -k * A * v^2 The force of drag F is proportional to the velocity v squared. k and A are...

First off, sorry if this is the wrong forum but I wasn't sure where else to put it. Secondly, this will be just an interest because I've already applied to and chosen by university degree courses so I'm not considering a career in aerodynamics. I want to start out with just understanding the...

Hi, Let's tie a sphere, drop it into a water and trawl it with a boat. How do we calculate the angle between a vertical line and rope? Actually I don't know much about aerodynamics and hydrodynamics so I don't know how drag force is calculated from shape, mass and speed of an object. Recently...

Hi, I'm doing a looong assignment on aerodynamics, and have just about completed it. There are four points, however, which I cannot explain which refer to aerofoils. They are: 1. There is an upflow in air before contact is made with the aerofoil. 2. There is a downflow after contact with the...

What is the difference between Aerodynamics and Flight Mechanics?

What is INTAKE AERODYNAMICS ? Let's discuss it in datails. Any websites or reference?

Is there any website or reference for a beginner guide to Helicopter Aerodynamics?

What is Aeroelasticity? Is it one of the branches of Aerodynamics? :surprise:

Hey there. I'm currently studying to become a mechanical engineer, and in one of my projects I'm in need of some program that can simulate aerodynamics of different shapes. I only expect some kind of simple pogram, nothing fancy, but I don't know anything about this kind of program, so I...

This is a question about aerodynamics & lift/downforce created by a change in the undertray design of an IRL car.. The IRL racing series announced yesterday a number of changes to car design in order to keep cars from lifting off the ground, as they were for some unknown reason especially...

Your Aerodynamics are all Screwed Up! Rule #1) Never should the small end of an object that is intended to travel through a viscous (sticky & elastic) environment e.g. air, water, electromagnetic-spectrum etc... precede the larger end, to do so places the moving object in opposition to...

Hi, I've been designing a wing lately, and have been trying to figure out something. Hope someone could help. Considerations of small trim deflection have led to a design requirement of Cmac for the wing. I've been trying to figure out ways to reduce this to a Cmac value for the airfoil...

hello. the question is: if i have an exact model (and i mean EXACT) of, say, a glider (you know, those whaddamacallits, white things, long, thin wings, those ones), if i have one of those, why will it not fly as well as a proper one? (the model is a lot smaller than the real thing) i was...

Hey there Which methods or tools is there for scientists who work with aerodynamics? Only windtunnels with smoke sticks (and watertanks) and computersimulations based on calculations? Best regards Thomas Hansen
