NASA e phatlalalitse hore e sebetsa le Lockheed Martin morerong o mocha oa sefofane sa jete sa khoebo se khonang ho senya lebelo la molumo ntle le ho hlahisa sonic boom e tummeng hampe.
Ntho leha e le efe e tsamaeang sepakapakeng ka potlako ho feta lebelo la molumo e hlahisa leqhubu le tšosang le fetolelang molumo o lerata o tšoanang le ho phatloha kapa lerata le bitsoang sonic boom, le amang libaka tse khōlō, tseo hangata li nang le baahi ba bangata lik’hilomithara tse ngata ho tloha sefofaneng ka bosona.
The sonic booms e ne e le bothata bo boholo bakeng sa maeto a lifofane a phahameng ka ho fetisisa 'me a qobella lifofane tse ngata tsa Concorde - lifofane tsa lifofane tsa British-French turbojet-powered supersonic tse neng li sebetsa pakeng tsa 1976 le 2003 - lifofane li fokotsa lebelo la ho tsamaea ka tlas'a lebelo la molumo.
Jet e ncha, e bitsoang X-59, e ntse e ntlafatsoa ke Lockheed Martin's Skunk Works in Palmdale, California, le NASA e tlaleha liphello tsa tlhahlobo e “khothatsang” ea kotopo ea moea mofuteng o monyenyane oa sefofane sa eona se secha. T
liteko li netefalitse likhakanyo tsa nakong e fetileng tsa NASA tsa mohlala oa khomphutha tse bonts'ang hore jete e ncha e ka hlahisa lerata le tlase haholo, setsi se boletse.
Morero oa X-59 'Quiet SuperSonic Technology aircraft' (QueSST) o nts'etsopele bonyane ho tloha ka 2018. Setsi sa sepakapaka se fane ka $247.5 milione ho Lockheed Martin's Skunk Works e le karolo ea morero. Sephetho sa sefofane sa X-59 se ntseng se tsoela pele ho ntlafatsoa se ne se etselitsoe hore se be le lebelo la ho tsamaea la 925 mph, e leng makhetlo a 1.4 ho feta lebelo la molumo.
Ka X-59, re batla ho bonts'a hore re ka fokotsa li-sonic booms tse tenang ho ba ntho e khutsitseng haholo, e bitsoang 'sonic thumps,'” ho boletse John Wolter, mofuputsi ea etelletseng pele tlhahlobong ea X-59 sonic boom wind-tunnel.
"Sepheo ke ho fana ka boitsebiso ba lerata le likarabo tsa sechaba ho balaoli, e leng se ka fellang ka melao e mecha ea ho fofa ka tsela e phahameng ka ho fetisisa. Teko e pakile hore ha re na moralo oa sefofane o khutsitseng feela, empa hape re na le lisebelisoa tse nepahetseng tse hlokahalang ho bolela esale pele lerata la lifofane tse tlang,” Wolter a eketsa.
NASA le Lockheed Martin ba lebeletse ho qala liteko tsa sefofane sa pele ho elella bofelong ba 2022. Hajoale, mofuta oa jet o felletseng o ntse o etsa liteko tsa nako e telele setsing sa Texas, setsi se boletse. Lifofane "ka holim'a lichaba tse pota-potileng US" li tla qala ka 2024, e ekelitse.
