Ok all, I am very new to OPS so here is probably something that can't be done, but I am going to ask anyway.  Is there any way to link a keyboard key to trigger the obprob function? If we could do that then could we modify the engine horse power and rpm's using the engineMaxHP function? Thanks, Condor out ------------------

Usually most of the plane engines in SDOE are already set for 100% throttle to be WEP. As SDOE currently doesn't model engine damage due to extended periods of 100% throttle, there isn't a lot to model.IP: Logged |

I can think of 2 possibilities, not sure if either will work.1) have a second engine and hidden prop. Make it powerful, but thirsty. This could work if you can easily start and stop it. I know you can with the bombers. Balance it to give an extra boost. Not too sure about the physics here. Does a 2000hp engine plus a 1000hp engine make a 3000hp engine? 2) If you can specify different fule sources...which I don't think you can, you could give the WEP it's own fuel. When it's gone, no WEP. Idea 1 should work. Besides, using NO2 injection DID burn loads of fuel. Modelling engine damage would be the tough bit. Idea 2 would make WEP a limited resource. If they both work, WEP. Idea 1 could be useful if the SFC was high enough to deter extended use of WEP. Otherwise, no point in doing it at all! IP: Logged |

Mace's new Seafire has a "catapult" function that is in effect, WEP. I haven't had a chance to play with it yet, but I think it's kind of a one-shot deal. Basically a second engine that runs out of fuel at a certain point.You can specify additional engines, with their own engine start/stop key, and give them their own fuel tank(s) with limited capacities. I think Laika actually had working WEP at one point on an I-16 test plane, but I don't think he ever released it.

I don't know about "most" but the P38J is currently modeled to Military power only. I believe I recall Tailslide telling me that some of the LW aircraft are also set to MIL power. It would be nice to know what to standardize on as it makes a great difference in performance.... ------------------

Thanks for the info Jedi and Snickers.I will check out the second engine modeled by mace. It is better than nothing for now and also just for now we could say the second engine would give a 10% or 15% performance boost until we get accurate info specific to each plane. We could probably give it a set fuel load to control how long it can be used for. Time will tell and I am a bit concerned how extra fuel might affect the FM. Condor out ------------------

Yes, on the planes I did I picked roughly the highest power setting a plane could sustain for a decent amount of time (> 10 minutes). Giving the german planes unlimited amount of boost might unbalance the game. TS

We have accurate info on the P38... (well about as acurate an anyone elses...  ) If this turns out, I would like to look at including it in the next release of the P38J. Unfortunately they wont the the pilots up at Chino kick in the high power often or long but I may drive up there and see what I can find... Only so many 38s left flying...  ------------------

I tried the second engine as a booster for WEP on the P-51 a while back. Actually it works great, but just a couple of problems.You have to manage the engines as if it were a multiple-engines plane. If you use "E" to start the engine it also starts the booster. You can turn off the booster by pressing Shift 2. Here is the problem. If I press "E" to shut down the engine, the main engine is no shutting down but the booster (engine 2) is now starting. I thought this might be too confusing for newer members, so I pulled it. I thought about adding an object with a lot of drag, and disable it with a key-press, with the reduced drag it would seem to have a boost. As it is now the engineMaxHP RPM and HP can only be reduced to simulate damage. I have not been able to make it increase the same way. This would require a minor code change, but would be the best way. If we had a function to increase the engineMaxHP for a max time limit. I think this is possible, we just have to be patient, until MH, Mighty and crew can finish up thier current project and then suggest it kindly. IP: Logged |

Mace's catapult engine uses an aerfoil which rips at a certain speed, calling a function which kills the motor. It switches it to a no-fuel situation. Fuel consumption isn't a problem if you set the SFC at 1. If the engine has little weight, the FM won't be effected. It is, however, a one shot deal. Once the airfoil breaks off, you can't re-use the function.great for a catapult, crap for a wep simulation! IP: Logged |

Hi WT,No problem. Can't we just have the airfoil rip at a higher speed and then set up the alternate fuel tank to empty on it own? I really am not sure, but I hope something like this is possible to do. Condor out ------------------

Can you set it up to start with an empty tank, and then when you hit the key for WEP you switch to the tank you really want to use? Just a thought...------------------

That should work!As far as I can figure it, you can tie a function to switch tanks to a key press. The big question is can you toggle that switching. If you can, you really can model WEP. Any OpenPlane Guru out there know if that can be done? IP: Logged |

Im sure you could implement my airfoil activation/deactivation method somehow to enable WEP. A propeller has an airsection just like an airfoil. Lets say you attach another hidden propeller that doesnt run off the engine to the existing propeller, and use my method of airfoil activation and deactivation. Then when you press the WEP key, that propeller object with its airsection and propeller properties are activated and thus cause more thrust! In fact, I think I'll go try this now!  IP: Logged |

In the damage model of the P47, I use functions that reduce the engine's power. We could add functions that increases it and lowers it. The problem is just that of limiting the total time you have available, and possible engine damage.

bjorn, I have seen the use of cylinders on your P47. Very clever! A problem with that however is enabling the WEP with a key press. Can you do that with the functions that you use with out any DOFs? IP: Logged |

Can you turn fire on and off? You can make WEP a HP increase to the engine, but at the cost of engine damage. IP: Logged |

Hmmm... that ripping airfoil deal on the catapault gave me an idea... could this be used to simulate overspeed damage to an engine? Make a foil that rips off at a certain speed and launches an obProb that reduces the engine RPM?Just an idea for the futrherment of damage modelling... -Stark IP: Logged |
