leey-7 aur isake baad key unnayan model leey-7aeye koo japan mein aich-III shrinkhala key prakshepan vaahanon key liye utpaadit dahan chakr lh/locks taral rockett injanon kaa manchan kiya jaataa haye. design aur utpaadan kaa kaam sabhi gharelu star parr japan mein kiya gayaa thaa, joe usa daave key saath pahala pramukh (mukhya/pratham-charan) taral rockett injan thaa, rashtriya antariksh vikas agency (nasda), aerospace engineering prayogshala (naal), mitsubishi bhaari udyogon aur ishikawazima-harima key sahyogaatmak prayaas mein. taba seey nasda aur naal koo jaxa mein ekikrit kiya gayaa haye. haalaanki, kaam kaa ack badaa hissa mitsubishi koo anubandhit kiya gayaa thaa, jisamen ishikawazima-harima turbo machinary pradaan kartaa thaa, aur injan koo aksar mitsubishi leey-7 (aeye) key roop mein sandarbhit kiya jaataa haye.
mool leey-7 ack vyay yogya, uchch dakshata, madhyam aakar kii motor thee jisamen aich-III parr upayog key liye paryaapt jore thaa.
aich-ii udaan 8, kewal parichaalan lii-7 viphalata.
eendhan turbopump mein mool roop seey design kiye gaye prerak (ack propeller jaise akshiya pump kaa upayog mukhya turbopump key aage pranodak key pravesh dabaav koo badhaane key liye kiya jaataa haye taaki guha koo rokaa jaa sakey) kaa upayog karke ack samasya thee jahaan prerak swayam guha karna shuru curr dega aur ack asantulan kaa kaaran banega jisake parinamswarup atyadhik compan hotaa haye. asafal 8vein aich-3 prakshepan key ack vyaapak udaan-pashchaat vishleshan, jisamen malabe kii ack gahari samudra punarpraapti bhee shamil haye, ney nirdhaarit kiya kii iss compan key kaaran honey vaali thakan samay seey pahale injan kii viphalata kaa kaaran thee.
leey-7aeye.
leey-7aeye leey-7 rockett injan kaa ack unnat model haye. mool model seey mool design aparivartit haye. 7aeye mein laagat mein katauti, vishvasaniyata aur pradarshan vikas parr atirikt engineering prayaas kiya gayaa thaa. ise isi tarah seey behtar aich-aaee. aaee. aeye. prakshepan vaahan key saath jodane key liye navinikaran kiya gayaa thaa, jiska samanya lakshya adhik vishvasaniya, adhik shaktishali aur lachila aur adhik laagat prabhaavi prakshepan pranali haye.
parivartan/sudhaar.
adhik machini yaa cast ghatakon kii anumati dekar aur shesh veldon koo yathasambhav saral banaane key liye aavashyak welding kii matra koo cumm karane parr vishesh jore diyaa gayaa thaa. isake parinamswarup pipe rooting kaa ack mahatvapurna punarnirmaan huaa (joe donon models kii baahari upasthiti koo kaafee alag banaata haye). oopar varnit eendhan prerak jatilataon kaa mukabala karane key liye, eendhan prerak koo 7aeye key liye phir seey design kiya gayaa thaa. oxidizer indser koo bhee phir seey design kiya gayaa thaa, lekin yeh mukhya roop seey vishvasaniyata chintaon key vipareet cumm inlet dabaav parr kharaab pradarshan key kaaran thaa. eendhan turbopump swayam bhee vibhinn sthaayitva vriddhi kaa vishay thaa. isake alawa dahan kaksh/injector assembly mein kaee chhote badalaav hue, jaise injector tatvon kii sankhya koo cumm karna, machining jatilata koo cumm karna (aur iss prakaar laagat) aur vishvasaniyata mein sudhaar karna. jabaki inn parivartanon key parinamswarup kull milakar adhikatam vishisht aaveg mein girawat aaee (mool roop seey injan koo cumm eendhan kushal banaana), cumm laagat aur badhee hui vishvasaniyata key liye vyaapaar koo sweekarya maanaa gayaa.
nayaa nozzle design (side-loading samasya).
nae injan model key liye, ack nozzle extension design kiya gayaa thaa jise atirikt pradarshan kii aavashyakta honey parr nae maanak "short" nozzle key aadhar mein jodaa jaa sakata thaa. lekin jaba injan koo nozzle extension key saath fitt kiya gayaa thaa, tou 7aeye koo abhootpoorv side-load aur nozzle parr aniyamit heating key saath ack naee samasya kaa saamana karna padaa joe startup key dauran gimbal actuators aur regenerative cooling tubes koo nuksan pahunchaane key liye paryaapt majboot thee. saavdhaanipoorvak computational fluid dynamics (see. aff. dee.) kaa kaam khatarnak kshanik loading koo paryaapt roop seey doharaane aur trace karane mein saksham thaa aur poorna punaryoji sheetlan key saath ack nayaa ack-tukada "lamba" nozzle (ack alag film-cooled extension key saath mool laghu nozzle key vipareet) samasya koo cumm karane key liye design kiya gayaa thaa. iss nae nozzle key taiyar honey seey pahale, kuchh aich-aaee. aaee. aeye. koo kewal chhote nozzle kaa upayog karke launch kiya gayaa thaa. 7a abb kissy bhee vinyas mein ack alag nozzle extension kaa upayog naheen kartaa haye.
aich-aaee. aaee. bee. parr upayog karein.
nae aich-aaee. aaee. bee. prakshepan vaahan apane pahale charan mein dou lii-7aeye injanon kaa upayog karate hain.
