  1. Well, that thing sure got whacked with the ugly stick, didn't it!
  2. ......sold many Landcruisers to weekend walliors who wanted to tear up their local sand dunes! So the Landcruiser became the oliginal unbreakable Toyota, and now, having given up our original militaly conquest, when it failed to ploceed, we succeed with economic conquest!! Turbo looked a bit thoughtful when the Japanese bloke expanded on the eventual Japanese conquest of Australia. Then he thought back to when all the Japanese invested in Gold Coast property and the signs started appearing around the GC, reading "オーストラリア人よ、ファック", which led to local outrage, even if..............
  3. It sounds like you've got a patentable idea, there Marty! Better hurry off for a meeting with Boeing before they read this! 😄 The only thing that I see would be needed, is that it it only operates when on the ground, or below "X" level of low speed (taxiing speed), say 40kmh.
  4. The GEnX engines in the Boeing 787 Dreamliner have increased thrust over previous models such as the CF6. The GEnX can generate up to 78,000 lbs of thrust at sea level, thus enabling the Dreamliner to take off with adequate power to spare, even at MTOW in high temperatures and high elevations.
  5. I can remember building a beautiful Kittyhawk about 65 years ago! It never flew! 😞 I could never get the engine to run! I never had any assistance in those days, living in a semi-rural area, so the Kittyhawk ended up collecting dust for decades! I can't even remember what happened to it. It probably got sold at a garage sale for a couple of dollars. That put to bed for good, all my dreams of flying aircraft!
  6. An AF-2S Grumman Guardian? Woo-Hoo! - now you just need the Carrier, to go with it! 😄
  7. QUOTE: "It's really a flying car!" No, it's not - that's just pure BS on a par with Trump BS and lies. It's a big passenger carrying drone, that's all. Plenty of companies worldwide, planning, designing and building them - none of them a "commercially success" yet.
  8. The trash media are using the altitude loss event of an Air India B777 to continue to smear Air India, and make it look like every AI aircraft is a crash waiting to happen. Re Red750's report - The AI B777, Flight AI-187, took off from Delhi during a violent thunderstorm. On climbout, the aircraft obviously flew into a severe bout of turbulence and a heavy downdraught. From official sources - “The (B777) aircraft was involved in an inflight occurrence of stick shaker and GPWS caution. Soon after takeoff, stick shaker warning and GPWS 'don’t sink' caution appeared. Stall warning occurred once, and GPWS caution occurred twice. There was an altitude loss of around 900 feet during climb. Subsequently, the crew recovered the aircraft, and continued the flight to Vienna." However, officials pointed out that the post-flight report for the Delhi-Vienna leg only cited, “stick shaker due to turbulence after takeoff,” without detailing other significant alerts. A deeper review of the flight data recorder (DFDR) - most likely as part of increased surveillance after the AI 171 crash - had revealed additional warnings, including a “don’t sink” GPWS alert and a stall warning, that had not been documented earlier. As a result, the flight crew have been temporarily suspended from further duties until the B777 altitude loss investigation is complete. Possibly the major concern around this incident is the GPWS warning sounding, which indicates terrain was far too close to the flight path.
  9. .......the same design features as the Japanese carriers - narrow gangways and low bulkheads to match the small stature of the Japanese, small hammocks for sleeping areas, food storage areas in the galley that are designed to hold bulk rice, and nothing else, and a tiny galley centred around the production of sushi and sashimi, and rice and ramen dishes only. The Australian navy officials inspecting the new ships were outraged that the personnel spaces were so small, they kept banging their heads and elbows and knees - and it was found most Navy personnel hated the smell of cooking rice, let alone the taste of it. This came back to the experiences of their WW2 POW fathers, which were passed onto their sons. What was worse, it was found the carrier decks were designed to the dimensions that precisely matched Aichi D3A's and Nakajima B5N's, and no current Australian aircraft could land on them. When official complaints were lodged with the Japanese, the Japanese responded with, "Ahh, so ... Ostralia contract did not stipulate..............
  10. Oil coolers are constructed to withstand much higher internal pressures than radiators. Oil pressure can reach 90 - 100psi (620-690kPa), but cooling systems rarely develop more than 16psi (110kPa). Accordingly, cooling system rubber hoses are relatively light construction, whereas any rubber hose components in lube systems, are very robustly constructed. In fact, it pays to eliminate rubber hose components in lube systems, if at all possible, as they're a major source of failure and resultant emergencies and often, serious engine damage. There's also the viscosity and heat-transfer properties of oil and coolant to be considered. Oil is very viscous and flows a lot slower than coolant, and coolant has an improved film transfer coefficient when it comes to heat transfer. Simply put, coolant disperses heat much faster than oil. Oil coolers contain fluid passageways that are larger in dimensions than radiators, thus if they're used for coolant, the coolant is in contact with a reduced surface area for heat dissipation, and therefore your cooling rate for coolant is lower than for a radiator.
  11. The AAIB has released a statement saying they expect to produce a preliminary report by about July 11th. But the preliminary report will only be around 4 to 5 pages and just confirm basic details of the crash. However, it may also indicate the lines of investigation, and therefore the pointers to the cause of the crash. The investigation is ruling out nothing at this point, and is including possible sabotage as one of the lines of investigation. This is not to say sabotage is suspected, only that they have to investigate the potential of sabotage, and examine any information (witnesses or black box evidence) that could increase the likelihood of any sabotage. https://www.ndtv.com/india-news/air-india-crash-probe-report-next-week-will-outline-damage-and-possible-causes-8807615
  12. ......the local goats, otherwise they'd not only eat the seat off the bike, they'd eat the tyres, too, then use the handlebars for toothpicks. However Turbo, being cluey about Aghani's and their goats as well, knew exactly what was required. Another thing he knew, from long experience, was never turn your back on an Afghan goat, because quicker than you can say "Khyber Pass", that goat will be.............
  13. Waay back in the late 1960's and early 1970's, I spent a lot of time driving earthmoving equipment, that all had open operator stations (read: no cabins of any kind). In Winter, strong Southerly winds would turn your fingers blue at the controls. So we found that the Military surplus stores sold heated flying suits! - cheaply! And they were 24V, too - and thus could be hooked directly into the Cats 24V electrical system! It was pure luxury, wearing these things on bitterly cold days and nights, with winds howling straight off the Antarctic ice floes, across the flatlands of the W.A. Wheatbelt! The only problem we found, was the suits were all cotton, and didn't stand up too well to the rigours of earthmoving equipment use! They had a relatively short life, as compared to the original designed use. But they were the bees knees, when those howling bitterly cold Southerlies blew in mid-Winter! Those winds were referred to as "lazy winds" - they went through you, rather than around you! I think Martys advice is excellent advice! The only other thing I could suggest, is some lightweight insulated panels glued to the interior of your aircraft cabin panels. You can even buy the stuff with the adhesive already applied to one side of it.
  14. Boeing have built 1,189 Dreamliners and they have flown billions and billions of miles, and this is the first Dreamliner hull loss, and the first double engine failure. So the problem is less likely to be a software fault, and more likely to be a combination of faults, or damage, beginning with a totally unforeseen mechanical or electrical failure that cascaded. I'm imagining a burst hydraulic pipe that short-circuited electrical wiring with metal shards, which then shut off the high pressure fuel valves. Something along those lines, and something never imagined possible.
  15. First it was the Russians attacking Ukraine, then it was Israel attacking Iran - now it's extended to Boeings attacking Airbuses! What is the world coming to? Can't everyone just live in peace? 😄
