Airbus Helicopters H225 flies on sustainable fuel

Reminded of Willie Nelson and his Bio-diesel Tour Bus: https://money.cnn.com/2007/09/26/new...willie_nelson/

Is it too ironic, given the 225's history, that it almost says 100% SAFE on the tail? :) Close but no cigar......
|
Every hour - Land, check the fuel level and change the MRGB?
|
Forgive my ignorance, but I've never seen a mention of the difference in performance of SAF vs conventional fuels. Are we safe to assume that SAF matches conventional fuels on performance or would it be too cynical of me to wonder if there is a reason why this isn't usually reported on?
|
The current development focus on safety, far from optimising, yet.

Let’s hope the rotorhead doesn’t fall off.

I wonder if, when viewing any other type of helicopter, you cite its history of mechanical failures and say “I hope that doesn’t happen again”. No, I though not. |
Well, considering only one rotor head ever fell of a 225 in hundreds of thousands of hours (may be even millions) it seems fairly unlikely. |

1 rotor head fell off in about 400k 225 hours. Its millions of hours if you add the 332 family, but then add another rotor head falling off G-REDL.
Here the topic was flight in SAF which I think is a cool initiative, by whomever and regardless of the aircraft type.. |
Wait for the first SAF-fueled R66 :)

as far as I have read, action has been taken by Airbus because of these events to prevent them in the future…. So indeed it is a bit silly to bring this up every time a 225 is mentioned. Regarding action taken by Airbus to prevent them happening again, even the latest Airbus Helicopters super medium product requires an MGB change at 800 hours. When an Airbus Helicopter super medium or heavy has an MGB installed that routinely makes a TBO of 4k or 5k hours, I will be more convinced. |

Here the topic was flight in SAF which I think is a cool initiative, by whomever and regardless of the aircraft type.. The actual reason for the S92 gearbox failure was identified and fixed - also if you were flying an S92, still fitted with Ti filter studs, and they failed, you should be able to avert disaster by landing/ditching immediately. Airbus admit they do not know why the gearbox failed in an unsurvivable way. They identified some potential causes and took steps to mitigate these causes. If the failure occurs again - everyone dies, and it’s “back to the drawing board” for further fixes. |

The difference in the examples you use is:

Does any of this gearbox stuff have anything to do with the original post?

But we still are no talking about SAF… do the exhaust fumes smell like French fries? 😉 The H225 test helicopter flew with an unblended SAF derived from used cooking oil, provided by TotalEnergies And only 50% of the helicopter engines run on 100% SAF, too |

According to the article,
And only deep frying leaves used oil. Which brings the next issue : how many kilogrammes of french fries must be cooked per flight hour? Given 2 liters of oil in a 1 kg deep fryer, and 10-15 uses before piping it to Total... And only 50% of the helicopter engines run on 100% SAF, too |
And so it begins
Wow, seems to be a real problem. Surge of cooking oil thefts in restaurants. Wall Street Journal.
Soggy French Fries? Blame the Cooking Oil Price Spike. ‘It’s Pretty Much Liquid Gold.’ |
