If you have the basice down then it's really just a matter of practice. Unless there's a specific method or command you need to understand better, you'll learn more by just using the program and getting familiar with it than you would by watching somebody else use it.
There are textbooks...
I'm not aware of a formal tutorial set for ProE like there is Solidworks. But even the tutorial didn't help me much until I understood the fundamentals of parametric modeling software.
What's your understanding of ProE so far?
I had the same feeling about the extra weight of vectored thrust, why I first thought about removing it. Initially it was seen as a necessity because the terrain mapping sensors onboard need to be kept stable while they process visual data. After looking into it I found out the airframe only...
I looked into doing a similar project a few years ago and worked out most of the details for a 12 inch fan, modeled after the GE90 engine. But I never had the time or resources to see the project through. If I remember correctly, I expected to achieve about 250lbs of thrust.
Does your...
I'm no expert on space but I would think that controlling the rocket's direction through vectored thrust rather than movable fins would result in better control in a low pressure atmosphere.
But perhaps you should clarify what you mean by "space". The Earth's atmosphere has several regions...
I'm working on a VTOL UAV with some upper classmen and I'm wondering if the design so far will be able to lift off the ground, and how much power (battery power that is) it'll need to hover at about 10 feet for 20 minutes. My concern is with ground effects and the amount of raw power needed to...
I didn't read through the entire paper but it looks similar to a method of flying a reflective disc with a high powered laser. The laser heats up the air directly under the disc, causing it to expand, thus pushing against the disc.
If I understand what I'm seeing it's just taking advantage...
pulse-detonation engines - or propulsion in general. Inertia-based navigation systems. Active 3D environment mapping (I forget what it's called but the radar/IR based system to let pilots see through fog/night). Dynamic airframe shapes. "Sonic boom" silencing to allow supersonic aircraft to...
I believe there's a an untapped area of study relating to high speed airflow over static surfaces - i.e. exhaust gas out of a turbine engine. Being able to silence such devices presents advantages for aircraft operating near urban environments.
supersonic flight has had a lot of recent...
The static coefficient applies UNTIL the object starts moving. Once the object is moving the amount of force required to maintain a constant speed is referred to as kinetic friction, or in the case of a wheeled vehicle, the rolling resistance.
Measuring the rolling resistance is simply...
Did you mean static coefficient or kinetic coefficient? The static coefficient only matters when the robot is stopped. Once the robot is moving the rolling resistance (kinetic coefficient) is what impedes motion.
A simple answer to your question is to look into brushless DC motors. You'll need a special motor controller to run it, but in principle they're much more efficient/powerful than standard DC motors and although they are technically AC internally, they can be powered from a conventional DC...
FYI...In case anyone is reading this thread for help with their own homework, I thought about the problem one last time before I turned it in and changed my answer. After receiving my homework back, with the correct answer, the actual formula would be sqrt((24gh)/(l^2)). The way to think about...
