Yechokwadi roketi sainzi mune petrolhead maitiro.
Nezvikonzero zviri pachena (kusavapo kweokisijeni), injini yekupisa yemukati haina kumbobvira yatorwa muchadenga… kusvika zvino. Roush Fenway Racing, chikwata chiri mujaho muNASCAR, chiri kugadzira injini yekupisa iyo ichabatanidza mishoni dzemuchadenga nechinangwa chimwe chete: kupa simba remagetsi kune spacecraft propulsion system.
Chirongwa ichi chikamu cheIVF - Integrated Vehicle Fluids - chirongwa cheUnited Launch Alliance, kambani inopa masevhisi ekutakura zvinhu munzvimbo. Chirongwa ichi chine chinangwa chekurerutsa kufambiswa kwemotokari dzemuchadenga mushure mekusiya mhepo yePasi, ichimisa kumafuta maviri chete: oxygen nehydrogen. Dambudziko guru nderekuti mazuva ano mapropulsion systems anoshandisa simba rakawanda remagetsi. Ndipo panouya injini yedu yekare yakajairika yemukati.
Kupa simba remagetsi kuhurongwa, Roush Fenway Racing yakawana mhinduro yakapusa uye ine hunyanzvi: inoshandisa diki inline matanhatu-cylinder injini inokwanisa kupa kupisa nemagetsi. Yakavakwa nemhando yepamusoro-soro, injini iyi 600cc, 26hp inofambiswa nemhepo yakamanikidzwa yeokisijeni, iyo inobvumira kuti ishande munzvimbo.
Mune genesis yayo, iyi injini inopisa mukati sevamwe vakawanda - matanda ekubatanidza, spark plugs nezvimwe zvikamu zvinobva pakunhonga - asi yakagadziridzwa kushanda kwenguva yakareba panguva yekutonga kwe8,000 rpm. Roush Fenway Racing yakatanga kuyedza injini dzemuchadenga dzeWankel (mune dzidziso yakapusa), zvisinei, chivharo chakatwasuka-chitanhatu chakave chakanyanya kukanganisa maererano nehuremu, kuita, kusimba kwekushanda, kuderera kwekudedera uye mafuta.
Mukuwedzera pakureruka kupfuura mabhatiri, masero ezuva uye matangi ekuchengetedza mvura, injini inopisa ine hupenyu hurefu hwekushanda uye kukurumidza kupisa. Parizvino, chirongwa ichi chinoratidzika kunge chiri kufamba - isu tinogona kungomirira kuti tizive kuti injini diki yekupisa iyi yekutanga kupinda muchadenga ichave rinhi.
