Question about "jet" strength

Post by Sting Auer on Fri Aug 12, 2011 10:11 am

Can jet strength be increased by making the part you use as the jet larger? I have a plan for a tank-busting missile, but I need to find a way to make the jet as strong as possible without cheating. It can only go up to 200, so I want to figure out it I can boost the jet strength by making the "jet" part longer, thicker, taller, etc.


So, will this work?

jet power is entirely dependant of the parent object's mass. this means that what really affects jet power isn't the jet part, but what it's attached to.

you can "cheat" by editing the .lbd file to increase the variable limit though. DWS.lbd does that already

It should be parent's mass multiplied by the jet's mass itself. Or has it been changed since 1.4.0?

Okay, so let me make sure I understand this:


a heavier model = stronger jets overall, correct?

So a car made out of metal E would have stronger jets than the same car made out of wood A, correct?

yes, but sadly it has the same accceleration because of the increased mass. but it suffers less from air drag!

@bwansy: here's an experiment which disproves that.

Code:
<?xml version="1.0" encoding="UTF-8"?>
<LB>
    <ATTRIB>
        <version>1.4.0</version>
        <TARGET>
            <u>-6.675</u>
            <v>2.775</v>
        </TARGET>
        <LUA>
            <index>bottom</index>
        </LUA>
        <DESCRIPTION>
            <text>This model has 8 jets, each one with different characteristics on mass for their child and parent objects.

the first 4 jets create the control group. while they are made from different materials and sizes, their acceleration is the same. this indicates that the thust force provided by jets is directly proportional to their mass, instead of their density.

the other 4 jets belong to the experimental group. the first two have a lighter child object, and the other two have a lighter parent object. even though both have the same mass, the first ones attain greater accelerations, while the other two aren't able to lift off out of the ground due to gravitational forces. also, the jet with the lightest child object has a larger acceleration. the control group features an increased child object mass when compared to them, but their acceleration is lower. this proves that the thrust provided by a jet is solely dependant of its parent object's mass.</text>
