This aircraft paper model is a Hawker Hurricane Mark II, a variant of British single-seat fighter aircraft Hawker Hurricane that was designed and predominantly built by Hawker Aircraft Ltd for the Royal Air Force (RAF), the papercraft is created by ThaiPaperWork, and the scale is in 1:100.
The improved Merlin XX (Mk.20) engine appeared in 1940 featuring a new two-speed supercharger that could have its impeller speed changed by the pilot depending on the outside air pressure (altitude). At about 18,000 feet (5,500 m) (effective), it would be switched to a higher speed gearing ("FS ratio" – Full Supercharge) for added compression, while below that, at its lower speed gearing, ("MS ratio" – Moderate Supercharge), it "robbed" less power from the engine.
The result was more power at both lower and higher altitudes, dramatically increasing the overall performance of the engine, peaking at 1,280 horsepower (950 kW). Because of the new engine the bay immediately in front of the cockpit was lengthened by 4 inches (100 mm). The carburettor air intake under the forward centre-section was redesigned and moved back 3 inches (76 mm). The more powerful engine was cooled by a 70% to 30% water glycol mix, rather than pure glycol used for earlier Merlin versions. This and the increased cooling requirements required a larger radiator and a redesigned, circular oil cooler housed in a deeper, slightly wider "bath". More information at wikipedia.
