I have not looked at the layout of the PTs but the difference in the number of engines may be due to the need to allow space for the dispensary with eight litters in the stern of the crash boats, or due to the additional weight of the torpedoes. These engines were built by the Packard Motor Car Company, and were a modified design of the 3A-2500 V-12 liquid-cooled aircraft engine. Elco and Higgins PT Boats and the British Vosper MTB's (Motor Torpedo Boats). Stanley Hooker's autobiography, Not Much of an Engineer, deals mostly with his work on Rolls-Royce jet engines. using for the crankshaft.

Melbourne using an Epilog Mini 50 watt CO2 desktop laser cutter, I want one of The received wisdom, at least in America, usually runs along the lines of: If Rolls-Royce birthed a stupendous engine, Packard brought American mass-manufacturing know-how to the equation, perfecting the design and mechanizing production. Language links are at the top of the page across from the title. Meanwhile Packard Electric would build wiring harnesses and create new types of wire to be used on aircraft and engines that would power both PT boats and bombers alike. Its factories may not have looked exactly like the clean, ultra-modern Merlin production facility Packard constructed at its East Grand Boulevard plant, as period footage shows: But the storied marque, or at least the aircraft engine-building portion of it, evolved to meet the demands of wartime.

Engine operating instructions are covered in the "Packard Operating Manual" and the "Packard 4M-2500 Marine Engine Construction Operation and Servicing Manual." The latter contains a wealth of information . All Packard M2500 engines came with cranking motors and DC generators built by the Delco-Remy Division of General Motors in Anderson, IN. That heritage goes back to the teens of the 20th century when small engines still had 12 cylinders. It would suck down 474 gallons of fuel an hour and propel a PT boat to the blazing speed of 40 knots while working with another identical engine. Packard built 14,000 marine engines during the war on East Grand Avenue, Detroit and the US navy's 768 PT boats were fitted with three of them, two astern and one amidships for ease of servicing . The pre and early world war II engines developed some 1200 brake horse power, this had been increased to 1350 BHP and then by the end of the war 1500 BHP, therefore a late war Elco 80' PT had three engines http://www.hemmings.com/hcc/stories/2006/01/01/hmn_feature17.html. improved versions with higher boost levels nominally made 1,500hp. The detail is amazing, I didn't expect them to come out so well, the rings This Packard 4M-2500 engine is one of approximately 12,700 built and is believed to have powered a US Navy patrol torpedo (PT) boat during World War II. The license built Merlin engines were not produced by Packard until well into the war years and were of smaller displacement (1670 CID). Packard-powered boats were consistent winners in the Gold Cup series. The audio on this one is mangled. British Merlins were eventually built at a quartet of facilities: Rolls-Royce Derby, plus two Rolls-Royce "shadow factories" at Crewe (currently Bentley's works) and Glasgow (twice the size of Crewe, its foundry provided castings for the other operations), and a Ford factory in Manchester. . A number of Ford engineers arrived in Derby, and spent some months examining and familiarizing themselves with the drawings and manufacturing methods. The three successive versions of these engines were designated as 3M-2500, 4M-2500, and 5M-2500, each of which had slight improvements over the previous version. Lot #37,084. the original engines were a boring at 2400rpm, some source state 1,800 hp.but that was the emergency rating at 2800rpm according to Packard documents. Crews needed to provide make-up water from their drinking water tank. It should be noted that the method of determining the octane rating has changed since that time and the same gasoline , if tested today, would get a lower octane rating, probablyby 5 to 10 points. One of my first idea's was to laser cut all the parts for a First of all, there were three Packard-powered Indy Cars in the 1923 Indy 500. $12.95 + $5.95 shipping.

However, using the older 4M-2500 engines, increases in the weight of the boats due to more weaponry offset the potential increase in top speed. The centre engine faced aft and drove the centre prop shaft Sadly, it is not as well-known for its incredible contributions, far out of proportion to its corporate size, to engineering - establishing standards for drafting, machining, etc. At the end of World War II, there was great availability of surplus equipment at unbelievable prices. will make up some laser cut laminations and hand wind some better coils but so Packard V12 Marine Engine that looks like the original V12 engine but is actually an A number of famous boats of that era used the powerplant including the Packard Chriscraft II and III boats and the Miss Packard, which competed in a number of unlimited races such as the 150-mile International Sweepstakes race. Like so many historical yarns, the idea that American know-how was able to build a better Merlin (either through greater precision or some degree of calculated, mass-producible impression, depending on whom you ask) than Rolls-Royce is hard to dispel out of hand. off. When it came time to build the V-1650, Packard was in an almost indisputably better place to build it in quantity than Rolls-Royce was when it began developing the Merlin in the early to mid-1930s.

If you have even a passing interest in automotive, aviation or military history, youve probably heard some variation of the Merlin tale. ", see: http://www.hemmings.com/hcc/stories/2006/01/01/hmn_feature17.html. That designation was V12. Theres an appealing counterintuitiveness to the notion that a (marginally) sloppier engine makes for a more effective fighter plane powerplant; its a bit like that chestnut about adding armor to the parts of the bombers with no bullet holes. It is larger, lighter-per-horsepower and has more parts than the automobile engine. The other thing was that when we were on patrol we idled all night so when we started back to base all engines were running as fast as they would go for maybe 2 hours.

Packard marine engine that were produced in their thousands during the war to power the U.S. directly, whereas the port and starboard wing engines faced foward and drove into Packards early efforts resulted in the successful Liberty V12, which arrived several months after the United States April 1917 entry into World War I. Rolls-Royce began producing its Eagle V12 in early 1915, also to power warplanes; it started development of the PV-12, the engine that would become the Merlin, in the early 1930s and had running prototypes by 1933. One of those cars was a 1919 Packard with a straight-six engine, while a 1923 model carried a V12 powerplant, probably a variant of the smaller V12s of the time period. The 3A-2500 was an improved version of the 2A engine used on the Huff-Daland XB-1 Liberty bomber of World War I vintage. In twin-screw installations the ideal arrangement is to have the tops of the propeller blades turning outward for better maneuvering qualities but this was not available with the Packard engines in the 85s which made docking a bit more challenging as it was almost impossible to get the stern to move to starboard. had heavily modified the engines in P-563, P-564 and P-565 to achieve speeds of about 55 mph and added a muffling sytem for low speed stealth operations.
