Energy fighting in combat flight sims

AI Thread Summary
Energy fighting in combat flight sims focuses on optimizing maneuvers like boom and zoom to conserve energy while engaging a lower target. The discussion highlights the impact of friction on energy loss during directional changes, emphasizing that the force of friction varies with velocity and path. Participants suggest using integration to understand the complexities of friction forces, acknowledging that analytical solutions may not always be feasible. A simple model of friction is sought to provide intuitive insights into these dynamics. Overall, the conversation underscores the importance of minimizing negative work to enhance performance in energy fighting scenarios.

Hello everyone, I have a question regarding energy fighting. Suppose you're flying a plane and you want to boom and zoom a target that is lower than you, flying at similar velocity. What is the optimal* way of diving and then zooming up again.

*optimal wrt energy conservation.

I'm aware of the fact that how much negative work friction does depends on the path, but what confuses me is that when the plane changes direction the force of friction changes, also iirc it depends on magnitude of velocity.

P.S. Don't be shy to throw in some math :) Cheers.

You are aware that control surfaces don't give you "non-skid" responses, that there are delay times that are functions of all sorts of things?

Yes and you want to minimize that negative work.

That means you have to use integration, and might not find an analytical solution for all cases.

Well, I'm looking for a simple model of friction force that would give me intuition regarding the issue.

Suppose that the upper and lower bound of a 2D region is given by 2 smooth functions where these 2 functions represent paths, that would be good enough.

Cheers
 
Thread 'A quartet of epi-illumination methods'
Well, it took almost 20 years (!!!), but I finally obtained a set of epi-phase microscope objectives (Zeiss). The principles of epi-phase contrast is nearly identical to transillumination phase contrast, but the phase ring is a 1/8 wave retarder rather than a 1/4 wave retarder (because with epi-illumination, the light passes through the ring twice). This method was popular only for a very short period of time before epi-DIC (differential interference contrast) became widely available. So...
I am currently undertaking a research internship where I am modelling the heating of silicon wafers with a 515 nm femtosecond laser. In order to increase the absorption of the laser into the oxide layer on top of the wafer it was suggested we use gold nanoparticles. I was tasked with modelling the optical properties of a 5nm gold nanoparticle, in particular the absorption cross section, using COMSOL Multiphysics. My model seems to be getting correct values for the absorption coefficient and...
