LOHAN dives into Reg forums mosh pit
At the behest of reader Joeman, there's now a Reg forum open into which which you can throw your Low Orbit Helium Assisted Navigator (LOHAN) comments and/or suggestions. Click here for a bigger version of the LOHAN graphic We reckon this is a better place to slog it out than in comments on individual stories, because we find we …

Question
Have you considered hydrogen instead of helium?...
*cough*
Re: Question
Thank you for asking, that was the exact reason why I entered the comments section.
Re: Question
I do hope that's not a smoker's cough you have there.
Lohan does remind me of
the ship from When Worlds Collide. Apocalypse, evacuation of the Earth etc
Is there something you're not telling us?

You might want to dispense with the aluminium plate. The jet thrust impinging on the plate might push the payload on its suspension cable into an unstable oscillation before the plane has had time to accelerate clear of the guide rail. Instead put a collar on the guide rail for the plane to rest against.. Or turn the aluminium plate until it's edge on to the the rocket exhaust
Re: reaction
I would think the plate would help maximize the thrust, as it would in any environment. Any unwanted "oscillation" shouldn't matter in the fraction of a second it takes to clear the rail. Have you ever launched a rocket G R Goslin?

It's a start ...
What does physics say?
Does a plate behind the exhaust actually have any effect on the forward acceleration?
I remember seeing it as a physics question but can't remember which way the answer went.
I definitely think a ground test should be done to check the induced swing the platform gets before the rocket leaves it. A dangling platform takes very little to get moving....
Re: What does physics say?
It (the plate) doesn't help the rocket. If close enough it may even hamper with initial acceleration as the exhaust stream is redirected to undesirable directions.
Thumb down, not for your question but for the plate.
