Too late. https://www.pipistrel.si/plane/alpha-electro/overview -- Regards, Joerg http://www.analogconsultants.com/ What do you suppose they do when the lithium ion batteries overheat and catch fire? Pretty much the same as when a fuel line comes off and flames and plumes of black smoke start showing up from underneath the cowling on a regular aircraft. You either find a somewhat decent place to immediately land or you have a parachute, are able to open the canopy or a door and manage to leave the aircraft without hitting the stabilizers. In big airplanes with lots of engines the first step was to reduce power or stop the bad engine and dive the airplane to increase airspeed and try to blow the fire out. Been there, done that and it worked (at least that time :-) cheers, John B. In commercial airliners, the battery bank is located in the nose directly beneath the wiring harness for all of the cockpit instrumentation. https://tinyurl.com/y84qh6v5 The 787 has two battery compartments, the forward one is located aft of the front door, which is aft of the pilot's compartment. Lithium Ion batteries can only be charged at their maximum rate between 1/4 and 3/4 of full charge. On either side of those lines you have to severely limit the rates of charge to not overheat the batteries. Foreign airline companies would NOT rent ground power units during layovers and so the cleanup crews would be using the batteries to power the lights and cleanup equipment all during this time. The smaller the clean-up crews the longer it would take. See: https://www.aviationtoday.com/2013/0...87s-batteries/ 'These four busses are 235VAC primary power and 270VDC for pumps, plus 115VAC and 28VDC for small galley, IFE and flight deck subsystems. The ship relies on the low voltage DC 29.2VDC from the lithium battery only for engine starts if no ground power is available, for some power transfer functions and for last ditch back up emergency cockpit power. For it to actually be needed in flight, all six onboard generators would have to have failed, along with the emergency wind turbine. Normal starts are from one of the external ground power ports, with the required energy supplied by an external ground power unit. Where a ground power start is not possible, the rear internal battery starts the APU, whose high capacity VFSGs then provide the power needed to start the two main engines forward. So after the engines were started the original chargers would run the recharge at maximum rates until the battery reached full charge. This left a serious source of a battery fire and that fire would burn out all of the control and communications lines. This is what probably occurred to that aircraft that disappeared. Those Boeings would fly themselves and it probably first killed the pilot and copilot with carbon monoxide. Since their are locked into a break-in proof cabin no one could get in. Then the burning batteries would go though the forward bulkhead and into the luggage compartment and the remainder of the passengers would be killed by fire or carbon monoxide. The aircraft would respond to the weather conditions but more or less simply fly itself until it ran out of fuel and glided in and crashed into the ocean. The radar track of that aircraft looked like that was the case. cheers, John B. |

Sound good until you picked the wrong pair of culprits. Hint, look at aircraft crash reports and you'll find it is rarely "fire" that kills passengers, but smoke. |

I even remember one case of the battery, or components near the battery catching fire on a C-47 (DC-3 to the uninitiated). The battery is located in the nose forward of the cockpit and when they fired the fire extinguishers to put the fire out the CO2, as well as putting the fire out, flooded the cockpit with CO2 which also "put out the pilots" causing a crash.

Slocomb wrote: Today's Bangkok Post had an article entitled "US careens towards government shutdown". From reading the article it seems that the President wants a 5 billion dollar budget for the Mexican Wall and Congress doesn't want to give it to him. 5,000,000,000 divided by 1,954 miles is what? $25,588,536.33 a mile (that may be wrong as I'm not used to working with really big numbers) but even for the largest economy in the world that seems a tiny bit expensive, doesn't it? It's about $2.5M per mile which sounds cheap to me, considering all the surveillance stuff that goes into it. Maybe you need a new calculator :-) You missed that part where I say, "(that may be wrong as I'm not used to working with really big numbers)"? I didn't miss that, just couldn't believe it because AFAIK you are an engineer and also worked on aircraft. Those are professions where some really big numbers occur. Yes, I did graduate from a so called "diploma mill" engineering school and yes I did work on airplanes but the largest numbers we worked with was gallons of gasoline in the fuel tanks which, I suppose rather dates me as I never worked on a jet aircraft :-) Who knows, maybe 100 years from now anyone who worked with Jet-A has to be an old fart. My 36 year old road bike doesn't instill youth appeal either. "Wot's a downtube shifter?" I originally served an apprenticeship as a machinist where the biggest numbers were in 1/1000 inch :-) If you never worked on the electronics you might not have experienced really large ranges. There we routinely deal with ranges in excess of 12 orders of magnitude. Though 0.001" versus the wing span can be five orders of magnitude. -- Regards, Joerg http://www.analogconsultants.com/ Slocum has big plans for inventing an electric aircraft. Too late. https://www.pipistrel.si/plane/alpha-electro/overview -- Regards, Joerg http://www.analogconsultants.com/ What do you suppose they do when the lithium ion batteries overheat and catch fire? Pretty much the same as when a fuel line comes off and flames and plumes of black smoke start showing up from underneath the cowling on a regular aircraft. You either find a somewhat decent place to immediately land or you have a parachute, are able to open the canopy or a door and manage to leave the aircraft without hitting the stabilizers. -- Regards, Joerg http://www.analogconsultants.com/ What percentage of aircraft have fuel engine failures vs. the number of lithium Ion battery failures? So many of these have occurred that you'd think that the government would step in. But the media doesn't even report the vast majority of them. There were aircraft ground fires that I explain to them how and why they sere occurring and they did take actions. But I'm not sure that they are watching that closely enough. The FAA reports that there were 18 lithium Ion battery problems so far in 2018. There were 219,004 licensed aircraft in the U.S, in 2018. cheers, John B. 219,004 Boe3ing 987's. Who would have believed that Boeing could have turned out so many. I see... the 987 is the only aircraft that uses lithium Ion batteries? A strange remark as I read: https://www.aviationpros.com/article...es-in-aircraft Lithium-ion batteries have been a significant part of aviation for the past decade. Applications have been used in systems such as avionics backup power supplies, emergency lighting, ELTs, powering auxiliary equipment (crew cabin phones, cabin doors), uninterrupted power systems (UPS), and engine start batteries for fighter jets and drones. http://aviationweek.com/commercial-a...ove-value-a350 After 1.5 years of service with lithium-ion (Li-ion) batteries, the Airbus A350 is quietly proving the worth of a technology that suffered from serious teething pains on other aircraft. Along with the recently certified Bell 505 Jet Ranger X helicopter, another turbine-powered aircraft using the batteries, the A350 may herald a broad adoption of Li-ion in civil aviation. Noteworthy will be Boeing\u2019s upcoming choice for its code-named New Midsize Airplane. For Li-ion batteries, the road ... Christian Bible - Proverbs 17:28 Even a fool, when he holdeth his peace, is counted wise: and he that shutteth his lips is esteemed a man of understanding. cheers, John B. You didn't seem to notice that I had a typo and that it is 787 and 797's.. You don't understand anything about batteries so I suggest that you looking them up on Google to appear knowledgeable simply makes you look even more foolish. Yes I did. Thus my satirical response that "I see... the 987 is the only aircraft that uses lithium Ion batteries?" (satirical - exposing human folly to ridicule) Sort of like you supremely ignorant comment about fires not being the cause of death but rather carbon monoxide. Moat people would be aware that a fire in an aircraft that is 20,000 feet above sufficient O2 to sustain a fire would generate CO if any fire was started in the luggage or main wiring compartment. Let's here you say something really stupid again. Tom, I spent 20 years working on or about aircraft and yes during that period we had some fires. I even remember one case of the battery, or components near the battery catching fire on a C-47 (DC-3 to the uninitiated). The battery is located in the nose forward of the cockpit and when they fired the fire extinguishers to put the fire out the CO2, as well as putting the fire out, flooded the cockpit with CO2 which also "put out the pilots" causing a crash. With each comment you make you're showing more and more that your fund of knowledge isn't from any sort of personal experience but from the might Google. I think that you misspelled another word. "might" means physical strength or power, not "google". As I keep telling you, "It's better to keep your mouth shut and appear stupid than open it and remove all doubt." cheers, John B. But since you don't live here and don't know a thing about this country anymore you're nothing more than a google fanatic. A fool by any other names is still a Slocumb. |
