http://www.finleyweb.net/Portals/0/Aviation/EJ-22/EJ22-2003July20-2-500.JPG Subaru engines apparently get recycled into private airplane engines >
the guy that used to work on my old Legacy GT is an airline mechanic and he said that the engines for subaru's are almost identical to some airplane engines. makes sense now that I see it.
can anybody explain the advantages of subaru engines vs the mazda rotary engines? from what i know, the rotary engines are similar to aircraft engines.
i don't think anyone is dumb enough to put a wankle in an aircraft, subuaru and rotory engines have nothing whatsoever in common.
furthermore the subaru engine is quite a bit more durable (actually any piston engine is more reliable)
This is fairly old news, they've been using Subaru engines for years. The 1.8 and the 2.2 are very common swaps indeed. Porsche was also known for this, although their engines alone cost upwards of 100k. Auto engines have much better service intervals than aircraft engines and typically have better technology involved in them. There are a few aircraft engine companies that use a horizontally opposed engine design, Lycoming is one of the main ones IIRC. And there are Wankels being used in aircraft/ultralight applications. It does lend itself rather well, being that they're compact and lightweight: http://www.ultralightnews.com/sunfun99/wankel.html http://www.rotaryaircraftengines.com/
I'm not doubting that they used them....would i trust it to haul me around thousands of feet above the ground? not a chance in hell..
You are correct, and IIRC, the planes that bombed pearl harbor were made by Subaru? I should say, they were made by the company that later spawed Subaru.
Many modern day car companies were also involved in aeroplanes at some point. Mitsubishi, BMW and Rolls Royce all spring immediately to mind.
Subaru = Nakajima Aircraft Co. Made several different bombers/fighters for Japan in WWII. Mitsubishi = Among other aircraft, the famous Zero fighter. Lightweight, long range but lacking armor and self sealing fuel tanks. BMW = Supplied engines for the FW190, ME109 and JU88, among others Rolls Royce = The Merlin engine (and a few others). Powered the Lancaster, P-51, Spitfire to good effect Ford = Built B-24 Liberator bombers at its Willow Creek plant
um.. in a personal aircraft why not.. lets compare how many pissedon engines have crashed... many many... besides they GLIDE... not to mention you can get the REVS from a rotary... just like any engine if it is built right it will last.. again I state... I had a 200+ rotary that was daily driven ran mid 12s in street trim (1.2l engine) and was still running when I sold it 7 yrs+ after engine was built... it was built by a guy who helped build the Bathurst 24hr BP VISCO 3rd Gens who won back to back 1st and 2nd over all the piston powered competitors.. many whom blew their engines... all that said.. I would rather a subaru engine flying me around but a rotary engine for playing on the street...
Pretty sure Saab is another big one... I work at an airport and can easily see the simularities between the subaru boxer engines and most of the small aircraft engines... The thing that confuses me is the rpm's... The propeller of an airplane is connected directly to the crank of the engine. Now I don't know of a single every day airplane that revs over 3-3.5k rpm. However the subaru (and rotary more so) engines make their power at a lot higher rpm than that. Do they gear the motor down to make power at lower rpm's? Or is it in the compression? How does that work?
They usually use some sort of reduction gearbox. I heard on some they just left the transmission in 2nd or 3rd and bolted it up.
Wrong, the first Mitsubishi to hit US soil was the plane that bombed Pearl Harbor ... another reason why I hate Mitsubishi!
So, If a subaru car engine was on a plane, that means they have an option to run 93 octane which should be cheaper i suppose to the higher octane Air plane fuel? maybe its an economic advantage
Most single engine airplanes can actually run anything from 80 octane ("mogas") to 110 octane. The most common is 100LL, but some airports carry auto gas or mogas.
my best friend is buying a new evo...and he's a huge american car fan :S im like why would you buy such a terribly built car :S
Isn't it true a big difference from the JDM Subaru’s and the U.S./European models is the fuel quality? I believe the JDM spec motors require 96+ octane.
not sure.. but I know in Australia that Premium is 98+ octane http://www.fuelwatch.wa.gov.au/info/dsp_fuel_types.cfm
