At the front, a large \u003cstrong\u003efan\u003c\/strong\u003e draws in a huge amount of air. A small portion of this air, the \u003cstrong\u003ecore flow\u003c\/strong\u003e, enters the heart of the engine: it is compressed by several compressor stages, mixed with fuel, and burned in the combustion chamber. The hot gases then pass through the turbine, which recovers part of their energy to drive the compressor and fan, before being ejected toward the rear.\u003c\/p\u003e\n\n\u003cp\u003eMost of the air, the \u003cstrong\u003ebypass flow\u003c\/strong\u003e, bypasses the engine core and is simply accelerated by the fan. This provides the bulk of the thrust in modern engines, while reducing fuel consumption and noise. The ratio between these two flows, known as the bypass ratio, is one of the major advances in civil aviation since the 1960s. This cutaway model allows you to visualize these two paths of air and the sequence of stages.\u003c\/p\u003e\n\n\n\u003c\/div\u003e\n\n\u003ch3 class=\"aa-title\"\u003eWhy you'll love it\u003c\/h3\u003e\n\n\u003cdiv class=\"aa-ben\"\u003e\n\n\u003cdiv class=\"aa-b\"\u003e\n\n\u003cspan class=\"ic\"\u003e✦\u003c\/span\u003e\n\u003cdiv\u003e\n\n\u003cspan class=\"tt\"\u003eA cutaway view\u003c\/span\u003e\u003cspan class=\"ds\"\u003eFan, compressor, combustion, turbine: the inside of the jet engine becomes clear.\u003c\/span\u003e\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\u003cdiv class=\"aa-b\"\u003e\n\n\u003cspan class=\"ic\"\u003e◆\u003c\/span\u003e\n\u003cdiv\u003e\n\n\u003cspan class=\"tt\"\u003eRotating blades\u003c\/span\u003e\u003cspan class=\"ds\"\u003eA battery-operated motor sets the blades in rotation for a vivid demonstration.\u003c\/span\u003e\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\u003cdiv class=\"aa-b\"\u003e\n\n\u003cspan class=\"ic\"\u003e➤\u003c\/span\u003e\n\u003cdiv\u003e\n\n\u003cspan class=\"tt\"\u003eThe pleasure of assembly\u003c\/span\u003e\u003cspan class=\"ds\"\u003eAssembling the engine yourself means understanding the role of every part.\u003c\/span\u003e\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\u003cdiv class=\"aa-b\"\u003e\n\n\u003cspan class=\"ic\"\u003e✦\u003c\/span\u003e\n\u003cdiv\u003e\n\n\u003cspan class=\"tt\"\u003eA metallic finish\u003c\/span\u003e\u003cspan class=\"ds\"\u003eThe metallic-surface PLA provides copper and silver highlights worthy of an exhibition model.\u003c\/span\u003e\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\u003cdiv class=\"aa-b\"\u003e\n\n\u003cspan class=\"ic\"\u003e◆\u003c\/span\u003e\n\u003cdiv\u003e\n\n\u003cspan class=\"tt\"\u003eA polished case\u003c\/span\u003e\u003cspan class=\"ds\"\u003eThe parts arrive arranged in foam, inside an elegant black box.\u003c\/span\u003e\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\u003cdiv class=\"aa-b\"\u003e\n\n\u003cspan class=\"ic\"\u003e➤\u003c\/span\u003e\n\u003cdiv\u003e\n\n\u003cspan class=\"tt\"\u003eA striking desk object\u003c\/span\u003e\u003cspan class=\"ds\"\u003eOn its black base, it stands out as a collector's item for aviation enthusiasts.\u003c\/span\u003e\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\n\u003c\/div\u003e\n\n\u003cdiv class=\"aa-des\"\u003e\n\n\u003cp class=\"t\"\u003eThe art of engineering at desk scale\u003c\/p\u003e\n\n\u003cdiv class=\"x\"\u003e\n\n\u003cp\u003eYou only need to have seen a jet engine up close, on the tarmac or in an air museum, to remember that impression of power: a \u003cstrong\u003ering of blades\u003c\/strong\u003e perfectly aligned, tolerances to within a tenth of a millimeter, and behind it, a whole hidden world.\u003c\/p\u003e\n\n\u003cp\u003eThis cutaway model makes that world visible.
