  • Modern diesel engines, in things like tanks, are often said to be multi-fuel and they can, like a turbine, can run on anything that can be vapourised and ignited by compression. Problem is, it often affects the lubrication of the engine and may ruin it, such as trying to run a modern car diesel on kerosene or biodiesel. Older diesels, with mechanical fuel injectors can routinely run on alternate fuels, ie, if you are stuck, you can fill up with waste oil or kero or filtered chip fat to get you home.

      your spot on, i once, for the craic threw 20l of veg oil from lidls into my 92 hi lux and it went like a watch, smelled like a chip van though.

        Lets hope that whoever is going to be adding up the pro's and cons' - select something that gives the best utility, and not just pick something that is expensive and 'sexy'!
        Actually Jet A1 is roughly half the price of Avgas (piston).

        • A. Ok, besides being powerful, running on cheap fuel, spread worldwide and taking a long time between servicing - what have Turboprops ever done for us?!

          vs.

          B. Really, the advantages of Piston engines are?.. (e.g. Cessna still sells five models of its traditional 'Cessnas' - all with piston engines,.. while its larger brethren are all turboprops)... I'm guessing again, cheaper purchase up-front with simple engines, take more abuse, more frequent maintenance but more simple servicing, and smaller airfields can store the (?) less dangerous (?) Avgas?
          (sounding a bit like a comparison between AC and DC motors now...).

          • Avgas is more volatile and dangerous to store and has lead in it, so it has to have dedicated transport and storage. Avtur lasts longer, requires treatment for microbiological growth in warm countries and is much safer to store. Piston engines can be finicky creatures and will never have the length of overhaul life that a turbine will have. PT-6s are unbeatable engines and are even used as industrial engines as the ST-6 model. They power helicopters, fixed wing aircraft, power stations and probably hovercraft and are simple to service and keep running.

                  Which would be more relevant to the AC Fighter thread below this one rather than in this thread.

                  • is there much point linking to articles that sit behind paywalls?

                    is there much point linking to articles that are so badly researched that they claim that the RAF used an aircraft that got turned into razorblades 5 years ago?

                    with respect, this has been happening for the best part of a decade - if a new policy is called for, why?

                      Because we effin well need to be in control of our own airspace?

                        This might just be the ticket actually http://www.vulcanair.com/userfiles/f...0_A-Viator.pdf

                        • These are all small airframes. They hate small airframes, the people who end up stuck inside them for hours. Why do you think they hate the Defender?

                          • Might have another visitor today, heard a PT6 whirring overhead in Dublin and thought it was a PC9... It wasnt

                            • if it's a PC-12, the registration just might be HB-FRY.

                              • 50kg payload
                                8hr flight time
                                150kts
                                400km range
                                STOL

                                50 kg is a lot of space for ISR sensors. You could fit a FLiR, hyperspectral camera, comms rebro etc
