This proved unreliable and when ethylene glycol from the U. The Hart was subsequently delivered to Rolls-Royce where, as a Merlin testbedit completed over hours of flying with the Merlin C and E engines. Fortunately, two designs had been developed: Production contracts for both aircraft were placed inand development of the PV was given top priority as well as government funding.

Following the company convention of naming its piston aero engines after birds of prey, Rolls-Royce named the Aviation costing methods the Merlin after a small, Northern Hemisphere falcon Falco columbarius.

As a result, the Peregrine saw use in only two aircraft: The Vulture was fitted to the Avro Manchester bomber, but proved unreliable in service and the planned fighter using it — the Hawker Tornado — was cancelled as a result.

Development[ edit ] Initially the new engine was plagued with problems, such as failure of the accessory gear trains and coolant jackets, and several different construction methods were tried before the basic design of the Merlin was set.

Common problems were cylinder head cracking, coolant leaks, and excessive wear to the camshafts and crankshaft main bearings. PV The initial design using an evaporative cooling system. First flown 21 February Failed military hour test in March Powered the Supermarine Spitfire prototype.

First flight in Horsley 16 July The Merlin continued with the "ramp" head, but this was not a success and only were made. Merlin XII Merlin fitted with 0. New larger SU twin choke updraught carburettor. Engine interchangeable with Merlin X. Revised Rolls-Royce unitised "Power Plant" installation design.

The Merlin III was the first version to incorporate a "universal" propeller shaft, allowing either de Havilland or Rotol manufactured propellers to be used.

The Merlin XX also utilised the two-speed superchargers designed by Rolls-Royce, resulting in increased power at higher altitudes than previous versions.

This substantially improved engine life and reliability, removed the fire hazard of the flammable ethylene glycoland reduced the oil leaks that had been a problem with the early Merlin I, II and III series.

Fundamental design changes were also made to all key components, again increasing the engine's life and reliability. This "cross-over" system took the exhaust flow from the inboard bank of cylinders up-and-over the engine before discharging the exhaust stream on the outboard side of the UPP nacelle.

As a result, sound levels were reduced by between 5 and 8 decibels. Still-air range of the aircraft was also improved by around 4 per cent. Cylinder heads fitted with cast-iron inlet valve guides, phosphor bronze exhaust valve guides, and renewable "Silchrome" steel-alloy valve seats.

Two diametrically opposed spark plugs protrude into each combustion chamber. Pistons Machined from " R. Fully floating hollow gudgeon pins of hardened nickel-chrome steel. Three compression and one oil-control ring above the gudgeon pin, and one oil-control ring below. Connecting rods H-section machined nickel-steel forgings, each pair consisting of a plain and a forked rod.

The forked rod carries a nickel-steel bearing block which accommodates steel-backed lead-bronze-alloy bearing shells.

The "small-end" of each rod houses a floating phosphor bronze bush. Crankshaft One-piece, machined from a nitrogen-hardened nickel-chrome molybdenum steel forging.

Statically and dynamically balanced. Seven main bearings and six throws. Crankcase Two aluminium-alloy castings joined together on the horizontal centreline.

The upper portion bears the wheelcase, supercharger and accessories; and carries the cylinder blocks, crankshaft main bearings split mild-steel shells lined with lead bronze alloyand part of the housing for the airscrew reduction gear.

The lower half forms an oil sump and carries the oil pumps and filters.IESF is a global conference program for electrical/electronic design engineers, managers and executives.

This course will examine the theory and practice of cost accounting. Topics covered include cost accounting system, responsibility accounting, job order costing, process costing, variable costing, budgeting, cost variance, cost behavior analysis and decision-making processes.
