purpi Posted March 5, 2018 Share Posted March 5, 2018 Each time you landed in VSTOL the water injector to the engine remains at 500 or 490 of consumption at the end of the landing. It seems strange to me that I do not inject almost any water into the engine when I land in VSTOL. My question is: The consumption of water injection to the engine is normal or not working properly.

thrustvector Posted March 5, 2018 Share Posted March 5, 2018 its probably as youre landing light enough to not need the water injected Link to comment Share on other sites More sharing options...
Eagle7907 Posted March 5, 2018 Share Posted March 5, 2018 It’s still correct to use the water injection, regardless if water is used or not. The switch also changes the thrust ratings on the engine, it’s just a plus that you finish a sortie light enough. Very smart to use it, at least until the VREST calculator is implemented, then you can know very accurately if you need water or even the higher thrust rating.

Esac_mirmidon Posted March 5, 2018 Share Posted March 5, 2018 The water injection depends on your RPM. The water flows when you pass certain RPM value. " You must think in russian.."

purpi Posted March 6, 2018 Author Share Posted March 6, 2018 Ok, I gather from your answers that my rpm when landing on VSTOL is not very high and that's why the water injector is not activated. Thank you Link to comment Share on other sites More sharing options...
Flamin_Squirrel Posted March 6, 2018 Share Posted March 6, 2018 The water injection depends on your RPM. The water flows when you pass certain RPM value. Temperature too depending on circumstance and switch position. Full details below as to what happens in each switch position. TO or LDG Water injection system is armed (engine JPTL datum changed) and the engine fuel control provides supplementary fuel resulting in an engine rpm rise at IDLE. The --408 engine increases 6.0 to 7.0 percent. TO Water flows when the throttle is set above 95 percent rpm for the --408 engine. After takeoff, water continues to flow until airspeed exceeds 250 knots, water is depleted, OFF is selected, or the throttle is moved below 103 percent rpm for the --408 engine. LDG Water flows when airspeed is below 250 knots, jet pipe temperature exceeds 765 °C (--408 engine), and the throttle is set above 105 percent rpm for the --408 engine. Water flow stops only if water is depleted, OFF is selected, or the throttle is moved below103 percent rpm for the --408 engine. After initial water flow, water will flow each time the throttle is set above 105 percent rpm, regardless of the JPT until the LDG mode datum is reset by cycling the H2O switch. OFF Shuts off water injection system. The OFF position must be manually selected to reset the engine jet pipe temperature limiter datum and engine fuel system.

Esac_mirmidon Posted March 6, 2018 Share Posted March 6, 2018 Right. The main reason is RPM setting but other parameters are taking in count also. " You must think in russian.."
