Most commercial jet engines are high-bypass types, which offer better fuel economy and lower noise. Most modern turbofans use two spools: a low-pressure spool carrying the fan, and a high-pressure spool, each turning at its own speed.\u003c\/p\u003e\u003ch3\u003eWhat to know\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eDifficulty 3 of 5; allow 2+ hours to assemble\u003c\/li\u003e\n\u003cli\u003eAges 16+\u003c\/li\u003e\n\u003cli\u003eMade to order: ships from our specialty supplier in about 2-3 weeks.
