TRW solved it with a variable-area pintle injector. Oxidizer (nitrogen tetroxide) flowed down the centre and out past a fixed pintle as a ring of individual sprays. Fuel (Aerozine 50) left the faceplate as a thin cylindrical sheet, and the oxidizer sprays broke it up and mixed with it. A movable sleeve, linked to the flow control valves, changed the size of both openings at the same time, so the mixture stayed right at every thrust setting.\u003c\/p\u003e\n\u003cp\u003eThe engine throttled between 10% and 60% of its 10,500 lbf maximum, or ran at full thrust; the range between 65% and 92.5% was avoided to protect the nozzle. On Apollo 13 the same engine pushed the crippled spacecraft back towards Earth. The pintle injector design later went into SpaceX's Merlin engines.\u003c\/p\u003e\n\u003cp\u003eThis print is the fine-line edition of the drawing: the engine in half-section, with Detail A showing the fixed pintle, the movable sleeve and the two propellant paths.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eItem\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003ePrinted on matte paper and set in a slim black frame, so the drawing reads like a sheet from the engineering office.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eCare instructions\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e- Keep out of direct sunlight to protect the print\u003cbr\u003e- Wipe the frame with a dry cloth\u003c\/p\u003e","brand":"Printify","offers":[{"title":"12″ x 16″ \/ Black","offer_id":47891119964358,"sku":"21682108426798841000","price":129.0,"currency_code":"USD","in_stock":true},{"title":"16″ x 24″ \/ Black","offer_id":47891119997126,"sku":"23677955682807715728","price":179.0,"currency_code":"USD","in_stock":true},{"title":"20\" x 30\" \/ Black","offer_id":47891120029894,"sku":"12882570278661957659","price":229.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0703\/4424\/5446\/files\/4450459944881176531_2048.jpg?v=1790438775"},{"product_id":"apollo-circuit-breaker-panel-framed-print","title":"Apollo Circuit Breaker Panel Framed Print","description":"\u003cp\u003e\u003cstrong\u003eDesign\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAlmost every system in the Apollo Lunar Module ran through a circuit breaker, and the crew used the breakers as switches as much as protection.

The software was woven into it. Core rope memory stored each program as copper wire threaded through small ferrite rings: when a sense wire passed through a core it read as a 1, and when it went around the core it read as a 0. The work was done by hand at Raytheon in Waltham, Massachusetts, mostly by women from the local textile and watch-making industries, who followed punched-tape instructions to thread each wire to the correct core. The engineers called it \"LOL memory\", for the \"little old ladies\" who wove it.\u003c\/p\u003e\n\u003cp\u003eBecause the code was physically woven, it could not be changed after manufacture.
