I-All-Russian Rocket Championship yokuqala yenzeke ekamu laseSoviet elahliwe eduze kwaseKaluga elibizwa ngokuthi iMillennium Falcon. Ngazicelela ukuya lapho, ngoba i-jetpack iseduze namarokhethi kunendiza. Futhi ukubheka izingane ezineminyaka engu-10 ezihlanganisa i-contraption esebenza ngempela kusukela ku-tape, iphepha le-whatman nebhodlela lepulasitiki, kuyilapho amaqabane amadala edubula i-rocket ngamamitha angu-400 kuyafaneleka.
Isifinyezo:
Amathrekhi
Lo mqhudelwano ubuqhutshwe ngezindlela ezintathu.
- "Amarokhethi amanzi" - izingane zesikole ezineminyaka engu-10-14 ubudala.
- "Amarokhethi anamandla aqinile" - iminyaka yabahlanganyeli iminyaka engu-14-17.
- I-“Open Skies” yamaqembu abafundi alungiselela imiqhudelwano yamazwe ngamazwe (ndiza ifike ku-10 metres).
Amarokhethi amanzi
Kusukela ebuntwaneni bami bamaSoviet, lapho izikhwama zepulasitiki zisawashwa futhi zomiswa ezitsheni zokugqoka, futhi amathini kathayela okuchithiwe nobhiya kwakuyizinto zokunethezeka eziqoqwe eziqoqweni, ngikhumbula le nto:
Kwabe sekuvela amabhodlela epulasitiki kwase kuqala inkathi yegolide yamarokhethi amanzi.
Irokhethi yesitayela se-punk.
Enye yamarokhethi amanzi amakhulu kunawo wonke emhlabeni.
Sekuyisikhathi eside imiqhudelwano yangaphandle iqhubeka futhi ijabulisa kakhulu

Kodwa i-rocket yamanzi ikhuphuke ibe ngamamitha angu-534:
$10,000 Umklomelo Wendiza Ephakeme:
Indlela yokwakha i-rocket yamanzi enenjini ezimbili:
Ngisho neNASA inakho :
Bekunjani ngathi
Iminyaka yombambi qhaza: iminyaka eyi-10-14
Isigaba sokuqala. Kwakudingeka ukuklama nokwakha i-rocket yamanzi
i-electronic on-board system kanye nendlela yokuhlenga esisekelweni (I-Arduino).
Isigaba sesibili. Kuyadingeka ukuklama nokwakha irokhethi ngaphandle komklami (umklamo wethu) ngohlelo lwe-electronic on-board kanye nendlela yokuhlenga. Ayikho imikhawulo yokuklama. Inhloso - ukufinyelela ukuphakama esiphezulu.
Ukuvakasha kwezincwadi nemibiko yevidiyo:
Amarokhethi anamandla aqinile
Isigaba sokuqala. Kuyadingeka ukuklama nokwakha irokhethi enesisindo sokuqalisa esifinyelela ku-1150 g ngohlelo lokulawula lwe-elekthronikhi kanye nendlela yokuphunyuka esisekelweni. I-Arduino.
Isigaba sesibili. Dizayina futhi wakhe irokhethi lomklamo wakho (ngaphandle kokusebenzisa umklami) ngohlelo lokulawula lwe-elekthronikhi kanye nendlela yokutakula.
*Amaqembu adlule esigabeni sokuqala noma amaqembu abafundi avunyelwe ukungena esigabeni sesibili.
Sindiza ngalezi zinjini:
I-TTX RD-100Injini eqinile ye-propellant yamamodeli e-rocket ye-RD1-100-7 izophakamisa irokhethi lifinyelele ukuphakama okungenakufinyeleleka! Iphupho labamodeli be-rocket le-MRE enamandla, ephikisana ne-analogue yaseNtshonalanga, selifezekile.
I-Russia iphinda ijoyina umjaho wasemkhathini ne-USA! Injini ye-rocket ye-RD1-100-7 inamandla kakhulu kune-Soviet MRDs. Manje abamodeli be-rocket baseRussia bangaziqhayisa ngokuphephile mayelana nokwethulwa kwabo okumangalisayo kozakwabo baseNtshonalanga.
Le modeli ye-rocket injini iqhubeka nomugqa ofakazelwe kahle we-RD1. Ubuchwepheshe bokukhiqiza obukhethekile nokubala okunembayo okuphezulu kwendawo kukhulise kakhulu amandla enjini.
Injini entsha yerokhethi yakhelwe ikakhulukazi abamodeli be-rocket abanolwazi.
UMKHAWULO WOMNYAKA
Kusukela eminyakeni engu-16!
IMICIMBI YOBUCHWEPHESHE

futhi kanje:
I-TTX RD-300Injini eqinile ye-propellant yamamodeli e-rocket ye-RD1-300-0 izophakamisa irokhethi lifinyelele ukuphakama okungenakufinyeleleka! Iphupho labamodeli be-rocket le-MRE enamandla, ephikisana ne-analogue yaseNtshonalanga, selifezekile.
I-Russia iphinda ijoyina umjaho wasemkhathini ne-USA! Ukuze ubambe futhi udlule imodeli ye-rocket injini ye-RD1-300-0, futhi sikwenzile. Injini enamandla kakhulu enga-odwa kithi kuphela.
UMKHAWULO WOMNYAKA
Kusukela eminyakeni engu-16!
IMICIMBI YOBUCHWEPHESHE
I-thrust ephezulu 330 N
I-average thrust 180 N

Isikhathi sokushiswa kukamongameli - cha.
IMIBANDELA NEMITHETHO YOKUSEBENZA
Gcina endaweni eyomile emazingeni okushisa asuka ku -20 kuye ku +30 °C.
Ukuthungela kwenziwa nge-igniter kagesi ekhethekile (etholakala kukhithi).
Faka i-fuse yonke indlela iye ekujuleni okungama-36 mm.
Lapho injini isebenza, yiba kude okungenani amamitha ayi-10.
Ukulungiswa kwenjini kunqatshelwe ngokuphelele.
Ishadi elilinganiselwe lokudonsa.
Ama-Fuse:
Nasi isithombe sendlela injini esebenza ngayo:
Futhi nansi isivivinyo esihlanyayo ngenjini yerokhethi eqinile:
Vula isibhakabhaka
Amaqembu abafundi alungiselela imiqhudelwano yamazwe ngamazwe ye-IREC
Ukuklama nokwakhiwa kwerokhethi yezindiza eziya ezindaweni eziphakeme ukusuka ku-3 kuya ku-000 wamamitha anomthwalo okhokhelwayo ongu-10 kg.
Izindleko zokwethulwa kwe-rocket kufaka phakathi injini: ama-ruble angama-24.
Kwenzeka kanjena nje umqhudelwano wamazwe ngamazwe wenzeka eMelika.
zibanjwe kusukela ngo-2006.
Amavidiyo avela emiqhudelwaneni yamazwe ngamazwe ye-IREC

Kusukela ngo-2017, umncintiswano we-ESRA we-Intercollegiate Rocket Engineering Competition (IREC) ube ngumsebenzi ohamba phambili womcimbi waminyaka yonke obizwa nge-Spaceport America Cup (i-SA Cup).
Ukubamba iqhaza okungenakuncintisana "Master"
Uma ngokuzumayo ungaphezu kweminyaka engama-23 ubudala futhi ufuna ukwakha amarokhethi, ungabhalisa iqembu kunoma yimaphi amathrekhi, okubonisa isigaba esithi "Master". Kodwa ukwethulwa ngezindleko zakho. Izindleko zezinjini eziqinile zikaphethiloli zisuka ku-5000 kuye kuma-ruble angama-35.
Izindaba ezivela emasimini
Imihlambi yezingane zesikole kanye nabeluleki bazo bezemfundo yafika futhi yaqala ukukhipha udoti emabhokisini afana nalawa.
Futhi uqoqe amarokhethi akho.
I-Scotch tape, iphepha le-Whatman, ibhodlela lepulasitiki...
... kanye ne-Arduino encane - irokhethi selilungile.
Kepha laba bafana bazombulala u-Elon Musk:
Namantombazane.
Ukuhlolwa kokuqala kwethulwa esikhumulweni sezindiza
Layidliva futhi kune rocket lamanzi.
"Ukwazi indlela nokuhamba ngayo akuyona into efanayo."
Ukubhekana neqiniso kwazuzisa ososayensi abaningi be-rocket. Ekugcineni othile waqonda ukuthi kungani kudingeka i-parachute.
Ukuqeda amarokhethi ngaphambi kowamanqamu
Iphrinta yephrinta ye-3D isikhathi eside... ungacabanga ngeminyaka oyiphilayo... cishe yonke eyishumi...
I-Master class ku-RimWorld ngenkathi i-fairing iphrintwa kuphrinta ye-3D:
-Iphi inja yakho?
- Well, wafa.
- Kungani efa?
"Yingakho eshonile, ngamngcwaba lapha."
Wonke umuntu nawo wonke umuntu babencokola nge-“Space Y”.
Ukugijima okwesibili enkundleni yezindiza kanye nokwethulwa kokugcina
Iqembu lamantombazane, elinye lawo lineminyaka eyi-10. Balinde ithuba labo.
Oxhumana nabo ukuqalisa ukude.
Umshayeli wendiza uzama ukubalekela rocket.
Inkinobho ebomvu.
Yethula iphaneli yokulawula.
Banakekela ingane yabo.
"Irokhethi enamafomula angalungile." Bazama ukulungisa izinto zikagesi ngaphambi kokuqala, nakuba lina.
Kufanele uze lapho kwethulwa ngerokhethi ehlanganiswe ngokugcwele, kodwa njengenjwayelo.
Ingabe isezingeni?
Zzzhhuuuh!
Futhi-ke amarokhethi aqala phansi ...
Umklamo womzimba wangempela. Kodwa uma bengadedeli i-parachute, bavele bahlakazeka.
Ngezinye izikhathi i-parachute yakhululwa, kodwa ayizange ivule - futhi ukwehluleka.
Futhi futhi.
Futhi futhi.
Ngempela sathola isikelemu kwelinye lamarokhethi ahlala phansi.
Ngemuva kwalezi zigcawu kwakunamaqembu okusesha agijima exhaphozini agubha izihlahla ze-birch aphinde agibela ezihlahleni ukuze akhiphe imali ekhokhelwayo. Bakhona abasuka ngempumelelo bafike behla, kodwa ubani onendaba?
Bekumnandi futhi kukhuthaza.
Ngethemba ukuthi amarokhethi azondizela eNyangeni naseMars, hhayi amazwekazi angomakhelwane.
Into ebaluleke kakhulu
Isidlo sasemini esikhumulweni sezindiza.
Abezindaba
Oxhumana nabo abahleli
PS
Irokhethi yabhajwa esihlahleni, iparashute yaphithana, futhi wonke umuntu waqala ukungibiza ngoba nganginendiza-jethi. Kodwa angikwazi ukundiza okwamanje, kodwa ngiyakwazi ukubophela idivayisi emigqeni:
