Best engine for aircraft/helicopter

[Kilinich]

Simple.
Good alternative to air friction engines.

It's good but it needs for power but when I put more in, it's less stable so what to do?

[KarateBrot]

it's less stable? i increased power tenfold but it's still unbelievable stable.

Well, I see few ways:
1) Scale up
2) Increase body density (and min circle density, default=5)
3) Adjust springs (decrease damping, tune hardness)

[Kilinich]

Here you are - x10 power. Easy.

This isn't really a very new design and I don't think its that stable.
Normal helicopter propellers gives a gyro stabilization aswell as lift.

Other than that I guess its good.

I'm playing around with a trusterengine that could give stabilization aswell.

Since it's impossible to make gyro stabilization in 2D it can be solved with thin box and big air friction.

Talking about stability and power it gives approximative 1:10 weight/power ratio and runs on any speed.
I didn't see that much for phun engines (except spawning but that type have a problem with speed)...

I think I'll tune it up a little to ungrade smooth thrust and power.

If you use a spawn engine that fixates the spawn balls instead you get the gyro "feature" for free. And for the speed I have a solution for that(its all in the math ).

I've see your thruster and I like it very much, but it not so universal as at first look, for example it's hard to make control with keyboard (need additional lasers) and it use complicated and not 100% "legal" things like custom geomID, plus it cause non-physics object handling.

This engine is simple to re-create for beginners and it gives constant force, just what is need for planes/helicopters.

p.s. btw - I'll stole your thruster idea for "ghost car" display in new racing game. It's easy to record and playback with such device. Thanks!

Your right, spawn engines that fixate the circles aren't very easy to make.

I've been working a bit on a solid state wing which gives the spawned circles the same speed in any direction as the plane. This gives a very close to real physics and ofcourse I add the "wing" behavior on top of that(not quite gotten the math right on that part yet).

Here is something like what I'm talking about(most of the thyme in there is for my solidstate wing):

Why would someone go through the effort of making thrusters? You COULD just go the simple route. Either a bouce-recoil thruster or follow this example.

viewtopic.php?f=18&t=1479
Download the hover ship for a helicopter example.
Download the F-14 one for an aircraft example.

Thats one of the stupidest questions I've read all day. Why do you make anything in algodoo if you consider it an effort not worth the "product"?

For your "simpler" route let me quote:

Make everything as simple as possible, but not simpler.

Your "solution" to be honest is a bad one, it limits imagination, by restraining the behavior the plain/helicopter can have and to top it off it doesn't look right while moving around.

Okay, you're excused if you weren't from the pre Algodoo Phun community, but my god man if you were Algodoo is well worth the few dollars it costs (or used to, I dunno if they're still doing the deal, ask someone like link if you're interested) to upgrade! really, the benefits are well worth the investment.


RaRa makes a good point here: If you're going to go to the trouble of doing something in Phun/Algodoo, do it right. Heck, this applies to everything in life. Do it once the right way and never do it again (or at least make it last longer). This applies to code as well as building a full sized house. if you do it right it should last a very long time. Doing things the quick, dirty, cheap way always leads to a big pain in the ass for someone else down the line.

This is why I am still working on my gearbox. Although work is very very slow (high school can do hat to a person, along with way too many other interests), I have continued in the hope that any Phun user in need of a gearbox can grab a few snippets of well written, well commented, glitch free code and make it work for them. that's the goal.

Why bother doing something if you're going to do a crap job and have to re do it later? If all houses were built to my standards they would last close to a thousand years (no lie) and require virtually no heating/cooling. But, standards exist that are not to stringent, and developers make houses on the cheap to maximize profits. Heck, even code. If you write all your code the right way the first time, it's easier to maintain and extend in the future. It's also easier for the next guy to maintain and use it, because your code, if written right, will ultimately outlast you.



So, in conclusion, if you want to do things the quick and dirty way, go ahead but be warned hat doing things as such garners you less respect for your work, and makes it more difficult to deal with later. The rest of us will stick to doing things the right way the first time, to save EVERYONE a lot of grief.

I don`t want to interrupt things, but you can basically make self stabilizing helicopter engines with two spawn-thrusters, simply based on negative attraction. Yoi just need beacons, picing up two positions on the flying object and some scripting
I`ve just finished a prototype of that:
http://www.algodoo.com/algobox/details.php?id=37262
It kinda flies a bit crappy yet, but you can better it in some ways, I`m already working on it.
So, err, did I even get the topic right here? xD
Anyways, Have a festering bucket of rancid prawnjuice!

Pretty nice, but what makes this better than a pair of good old rotary thrusters? The piston type can break, and cannot produce the same level of stabilizing affect you get out of properly arranged rotaries. And YES, both this and thrusters based off RaRaMalum's original design can both stabilize as they produce momentum. You just need to arrange them right.

Not to say this thruster isn't smooth. I'm surprised with how well you got a piston to work, but I don't see any benefits over more conventional density thrusters.
