    Falling Model
AI Thread Summary
A user is seeking assistance in creating a simple model of a Controlled Experimental Vehicle (CEV) falling straight down, focusing on physical characteristics like weight, surface area with and without parachutes, and thruster forces. They have a basic model in place and are looking for approximations to complete it. The discussion emphasizes the need for relevant data sources to aid in the modeling process. Additionally, a reminder is given about the importance of keeping conversations within a single forum to maintain clarity. The user is looking for practical guidance on obtaining the necessary information.

Hello,

I originally posted this in another category, but think this would be a better place for it...


I need to create a simple model of a CEV falling straight down (with some neglible initial horizontal velocity)

I already have a 'skeleton' of a model up and running. Basically, I just need to find physical characteristics such as weight, surface area w/ and w/o parachutes open, and forces of the thruster (approximations are fine).

Any ideas on where I could easily find this stuff? Thanks

Shaun

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...
I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
