Promotional; It was the 1950s; TV was feeding information about "Jets" and Americans couldn't get enough of how clever they were. The cars got "Jet Fins" and walked out the doors. People wanted Jet cars - one even had a modified steering panel and airctaft instruments. That Show truck was probably three parts wood/paper/clay, but clearly successful because both Ford and GM started developing gas turbine Tractors. Over the road trucks are close to cruise power applications, so it was a good bed and the engineers desperately tried to find a way of generating fast intermittant power, or covering the requirement with huge torque, but gave up. Here's a photo of the working GM version. You're being a little harsh on the GM financial story. GM was based on the 2 cents off a part equalling and extra million dollars net profit, and were one of the most successful companies in the world, but the US Government thought they were too rich and did a reverse Walmart on them, taking away their Frigidaire refrigerator division. That killed a complete factory in Dandenong Victoria and the area never recovered. They took their GM 2stroke diesel engine business , their Allison Transmission business etc. and GM was headed downhill.

If I we're into nit picking terms, the POH for the Piper Cherokee Warrior II lists several type of pumps in its system; no boost pump but 45 mentions of "electric" pump. Many of these were explanations of how you could diagnose issues, so a POH is well well worth reading. The name itself is not the issue; I was using it to get people's minds off it doing a "BOOST" job in this category where it is used as a backup system for the failures you describe. What the OP and several others were taking about was a boost pump to boost pressure. Rotax and Jabiru engines have been developed for the upper end of the RA class doing much the same job as the entry level GA. However what to OP is talking about is boosting pressure and reading a flow gauge and drawing conclusions. Brendan has just given a good example with his XAir or what can be fitted to RA airctaft, where the basic engine had a hand operation redundancy pump, and it's been fitted with an electric pump. These pumps are supposed to fill the supply line then stop when the basic conventional carb float valve closes. In this class of aircraft, which can have all sorts of engines including Harley Davidsons, and with conventional car carburettors with a float bowl and float valve, it can be a a long process to adjust the shut-off leverage to get that valve closed against the pressure of the electric fuel pump. Thats a PRESSURE problem. In terms of saving money by not using too much "boost" FLOW in the cruise on the above system at cruise is controlled by the main jet(s). You don't flirt with reducing jet size because you're only a whisker away from combustion chamber failure of valve heads, broken pistons and seizures, so no savings here. What's more likely is Brendan's experience, the electric pump hasn't cut out and is pumping fuel out of the Carb overflow, hopefully into an open-bottom engine compartment. When you turn the pump off the fuel "burn" per hour get's better. Since, if you know fuel burn at cruise for your engine at a decimal point per hour (not per Nm), you will immediately diagnose a fuel puymp cut off problem. If you have been practising the basics of electric pump control you probably won't know there's a problem unless you have a closed engine compartment and there is wet fuel or stain at the bottom.

.....a later iteration of Turbo's genuine Afro (he never wore flares though, he never wore flares.) The Afro had been a disaster, it shocked American, but in Australia, nobody noticed or commented, so it all went a bit flat at the BNS balls.nIt was useless for fox shooting; you'd be lying there behind a ridge with the fox whistle, and the fox would see this Afro sticking up and think it was someone from Mars Eh. Then there was the hay baling. Turbo was on the tractor bored after the 7,856th bale when he felt an irresistable force and he was dragged into the chute by the Afro. The tractor rolled on, the spool spun invitingly, but he held onto the safety bar like glue and the whole cover snapped, releasing him thanks to the crap New Holland design. After that......

Electric fuel pumps on Basic (training) GA airctraft were introduced as an extra safety feature in the case of a mechanical fuel pump failure near the ground. The Check list was: Pre Start: Fuel pump on, check making pressure. After Start: Fuel pump off Pre Take Off: Fuel pump on, check pressure 1000 feet: Fuel pump off Pre-Landing checks (downwind leg): Fuel Pump On After landing: Fuel Pump Off The reason for turning off after engine start and in flight was to avoid the situation where a fuel line might be cracked, or blow off at a connection and cause a runaway situation spraying fuel in the engine compartment until there's a fire or the smell makes you turn it off and hope. The pumps were not designed as "boost" pumps. They were simply a redundancy item like twin spark plugs and twin magnetos. The carburettors determined how much fuel they wanted to draw. On these airctaft if you get correct fuel burn, such as 49 litres/hr climb, 32 litres/hr cruise at 75% power (flight where no leaning is involved) they are consistent, and if you do your 10 minute (Not 10 Nm) checks the fuel tanks will usually be confirming your calculations, as will the refill at the end. If you record the details of every flight, and you've calculated the correct amount of taxy fuel, climb fuel, cruise fuel, descent fuel and taxy fuel, based on minutes, you should be seeing actual vs results (for equal flight times (not distances). (Using this data, if there's a strong head wind you can calculate and decide to return to base after 10 minutes cruise rather than an hour and a half later hoping you can make it home). Remember, fuel burn is always time based, not distance based; (the wind direction and strength decides distance.) Notice so far that I have stuck to basic training GA aircraft all built on production lines, all with a lot of testing, all with production components and all producing consistent results without tinkering. RA Airctraft, including self built are likely to have anything in their system, and in some cases producing less efficiency than the kit designer specified. RA "Boost" Pumps This implies a pump that boosts the pressure. If it really is a boost pump, and not just an incorrect name, this implies that a mechanical pump is fitted, but doesn't have enough capacity to supply fuel to the engine at full power. In this case if you don't have your boost pump working you could run the engine lean and get combustion chamber damage. (I suspect that people here are just mis-calling the name of the pump, but you never know.) Flow gauges Flow gauges are notoriously inaccurate; they can be getting different electrical inputs or they can be uncalibrated and showing inaccurate readings or they can be showing accurate flow at that second, but reading a situation which is temporary, such as reading high when lower pressure fuel is rushing to get up to pressure. Better to build fuel records on your engine based on Taxy, Climb, Cuise, Descent on your RA engine as a whole. If you want to save money, fly on calm days or where you can avoid headwinds.

...he was carving a name for himself as a Folk Singer, and often stood in for Peter, Paul or Mary if they were off colour. Many preferred him to Mary. Hower with the money he earned he put himself through University, majoring at Harvard in Fractional Electronics where, as we have just read somone could convert an old Avro Anson used as a chicken house for 75 years and convert it to the equivalent of a B2 bomber. He wasn't an extrovert like Werner Von Braun, he was descended from the German side of the family (his mother's first name was Germaine), and an introvert, but .................... Turbo did have problems in the trucking industry where the dress code at that time was singlet, shorts and thongs. (This was when trucks were mostly driven by Poms who called them Lorries apparently not being familiar with trucks. Of course today trucks are driven by Indians who are better dressed.) Turbo would just give them a hot curry head dress.

......pseudonym for Anmedsochtanistan (you can see why he had problems at loud parties) who was sent away to Karachi at the age of 7 to learn how to be a draughtsman. He excelled in his school and could draught goats by the age of 9, at which stage his father Ahmed kicked him in the butt and showed him the location of the engineering campus. He quickly picked up drawing and had a mirror memory and the eye of an eagle so an aircraft only needed to fly over head and he'd have an exploded drawing done. His Pakistani airctraft designs were legend and one of them was the famous Anson. Here we see the result of a bet down at the pub where Anson was asked to draw one with no glass. Turbo's grandfather, Sanjay Turbine, who did all the test flying has framed Anson drawing showing it flying without wings. In many ways Anson was the forerunner of AI. It was when he was designing the ........

It was in one of these decompression times that Loxie was caught on camera by the local press ....... In the Western District the best economic cycle for their meat production is to sow just enough seed to feed the stock through the dry season. At the end of the hey season there is a neat haystack on every farm. One of Turbo's neighbours had the longest paddock in the district, running beside the road for over a kilometres. It was only 150 metres wide but that's not the point. The farmer was like someone who buys an aircraft kit and never finishes it, full of advice but never managing to solve the problem. In this case he had no stock, but everyone else had a haystack so he also cut hay and started building hay at one end of the Long Paddock as he called it. With no stock, the stack was still there next year. No bells rang and he sewed another lot of seed and the stack was extended next year. Turbo would drive past every summer to see this stack growing longer and longer.The farmer wasn't worried about the cost; he sold suspension bits for Falcons. Eventually the ribbing from the neighbours stopped. He had the longest haystack in Australia, then the world. Some wag even put up a sign "BIG HAYSTACK: with two eyes painted at the end and a dot at the other. One night somone lit it at the upwind end and the rest is history.

4.11.23 Cloncurry light plane crash
turboplanner replied to trailer's topic in Aircraft Incidents and Accidents
Depends what happened at the hand over. We paid out big after a Race Car demonstration at a Shopping Centre. A track was marked out by orange plastic barriers (as a safety fence), the drivers of a variety of unrelated unsuitable cars were told to be careful. One went through the barrier and injured someone in the crowd. The car type was unsuitable for the track, and came under our jurisdiction so we were dragged in. (We didn't organise or take part in the display) Our defence centred around the Organising Official telling the drivers to e careful; we lost. -

......this only bought a japatti now and again so they contacted Turbine Consulting NL who suggested a Joint Venture (JV), and so they approached the current Chair of TATA Group, Nate Chandlershipac. First, a little history. TATA was founded in Bombay in 1868 by Jamsetji Tata. Jam's first words were "Tata" as he was waving gooodbye to his English mother, and when he grew up to be mayor of Bombay, in an emotional vote he had the Council change the name to Mumbai in honour of his Mum and early days, but that's another story. The Mayor often lunched with John Cholmonderau (pronounced "chum") Turbine at the Raffles Hotel, and it was John, with a 50 million Rupee donation (which secured half of India as his Tiger shoot) that allowed Jam to start building small cars. The company flourished thanks to Sir Dorabji Tata getting a licence to build Ford Prefect Estate Cars, and Sir Ratan Tata fitting engines in them. In 2008 of course the Tata Group bought out Jaguar Land Rover. It's no surprise that the products were struggling; and one wag suggested they were worth more as scrap metal. And so OT and Sanjeev found themselves booked on the next flight to Mumbai. In the plush Board Room, gold-lined and not a Punkah Wallah in sight, Nate explained the Turbine Cat Farm principle and suggested that he could build Jags and Range Rovers and the two businessmen could sell them as junk and he would buy the cheap steel to build more cars, and they could spread the process all over the world as TATA bought out other car manufacturers to ........
