| | Vizuálně moc pěkné, ale teda tím, že není simulována funkce kompresoru to podle mne pohřbívá celou 142... Je to zcela zásadní úkon pro spuštění motoru (bez připnutého kompresoru nemá startér čím točit), a pro jakékoliv režimy/úkony.
(A to se jen bojím, co udělali s korekcí směsi, jestli to je fakt korekce automatické regulace, nebo ten knoflík namapovali na obyčejný ovladač směsi ála Cessna)

| | If you've been following my posts on Zlin over the last few months, you'll know that (unfortunately) I'm NOT a programmer just a person who is a big fan of Zlins.
But I've put all my knowledge and free time into this project, trying to give the best and the most to the users - within my own limits. If you expect PMDG-like system simulation from me, you will not get it, please don't buy the plane, you will be disappointed!
However, there are still a few things that I unfortunately couldn't make as I wanted. As I fly this aircraft in real life, I am well aware of these shortcomings.
One of them is the implementation of the compressor operation. FS is familiar with the concept of supercharger, but its simulation is not exactly the same as the one in Zlin. I tried it. For example, I could not make it turn on and off by a lever or switch. Maybe this is just my lack of knowledge, but here I would refer back to the beginning of my post: unfortunately I am NOT a programmer. But believe me, I tried everything I could!
Of course, the development does not stop after the release, but the pace of development will be largely determined by how popular the Zlin will be on the Marketplace, and how worthwhile it will be to continue with it. If all goes according to my plan, I would like to have Wwise sounds made by experts, add more features and optimise the operation of some of the current ones.
But these further developments are beyond my knowledge, so they would also cost me a LOT of money, which I could cover with the income I have. That is why I am making further developments dependent on this. I am sorry if this disappoints anyone. |

Please don't apologize. You do maximum for development proces of this aircraft.
As for me, I am very much looking forward to your Z142. Even if, as you write, it will have a few shortcomings. Some models on the Marketplace are much worse than your Z142. I've been researching the SDK manual for making airplanes and it's a really complicated process. Sceneries has its complications, but airplanes are a whole other category.
Either way, I will definitely support your project.
I'm keeping my fingers crossed for you and good luck.

| | One thing I was always wondering about, how does the compressor work in practice? Is it a simple x1.2 manifold pressure, or is there a more insidious progress when it maybe results in +0.2 atm at higher throttle?

| | Ve většině případů je to první varianta - kompresor běží pořád předem daným převodem otáček (nebrat prosím za slovo, vím, že na M-332 a 337 ho lze vypnout, stejně tak například u Merlinů vyšších verzí lze naopak zařadit druhou rychlost). Existovaly ale i případy co popisuješ jako druhou variantu - konkrétně to použil Daimler u DB-601 a 605. Do plnicího tlaku 1.0 ata (respektive rovnocenného s tlakem vnějšího vzduchu) se otevírala škrtící klapka a kompresor běžel na velmi nízké otáčky a teprve poté při dalším přidávání plynu se pomocí variátoru zvyšovala rychlost kompresoru a tedy plnicí tlak rostl.
Obě varianty mají svoje výhody i nevýhody, ale to by bylo na dlouhé pojednání. V praxi se to ustálilo tak, že drtivá většina motorů s mechanickým kompresorem používá tu první variantu, dokonce bez možnosti jeho odpojení (s tím jsem se setkal jen na zmíněných M-332 a 337, jinak o dalším takovém nevím) |
