Air nemishonga simba - uye pasina chero nzira

Tiri saka kujaira rakombwa mhepo, izvo vasingawanzotauri kuriteerera. The pfungwa pano, kupfuura zvose, kushandisa unyanzvi matambudziko, mushonga iyo pakutanga inokanganikwa kuti pane simba mhepo nemishonga.

Rinotiyeuchidza zvoga munyika chero chinhu. Kunyange isu achaenda nemotokari, kunyange kubhururutsa ndege, kunyange kana tiri chete kukanda ibwe. Saka edza kunzwisisa kuti simba mhepo kuramba muenzaniso nyore kacho.

Makambozvibvunzawo here kuti nei motokari vane streamlined chimiro uye sandara pamusoro? Asi zviri zvechokwadi kwazvo zvakajeka. Air nemishonga simba rinoumbwa zvakawanda maviri - pose kukweshera kuramba mumuviri uye chimiro muviri kurwisa. Kuti kuderedza mvongamupopoto simba uye vabudirire rutapudzo kuti hadzina kufambiswa zvakanaka uye roughness pamusoro dzokunze pagondobwe motokari kugadzira zvimwe motokari.

Kuti vaite izvi, vari primed, akasvibiswa, yakabwinyiswa uye lacquered. workpieces kwakadaro kunotungamirira ndechokuti mhepo kuramba vachiita pamusoro motokari ipfupi, motokari nokukurumidza ichiwedzerwa uye huni manwiro ipfupi kana uchityaira. Pamberi kurwisa simba nokuti kuti kana motokari anozunungusa mhepo iri compressed uye pamberi payo pave munharaunda nzvimbo dzakakwirira kumanikidzwa, ichiteverwa ukuwo, ari Vacuum nzvimbo.

Zvinofanira kucherechedzwa kuti pane mukuru muchina kumhanya nomupiro chikuru muchimiro kurwisa kufambira motokari. Power nemishonga kukarukureta payakavakirwa riri pasi apa, rinotaura zvinhu vanovimba iro.

nemishonga Strength = CX * S * V2 * R / 2

apo S - pamberi fungidziro nzvimbo muchina;

CX - coefficient kufungisisa mhepo kuramba;

V - velocity;

R - mhepo arambe achirema.

Sezvo nyore kuoneka pamusoro payakavakirwa, simba kurwisa hakunei motokari vakawanda. The Mupiro chikuru chakagadzirwa zviviri zvinoti - yaiungana of nokukurumidza uye chimiro mumotokari. kureva nokuwedzera kuti velocity kuti kaviri kanosvika kuwedzera kurwisa. Zvakanaka muchinjikwa-sectional maonero motokari ine chinokosha simba. The motokari ichange yakawanda streamlined, rezasi mhepo nemishonga.

Uye nzira pane parameter kuti kungoti chinoda nacho kuteerera - the arambe achirema mhepo. Asi zvazvinoita rayo kare zvakawanda kutaurwa ndege. Zvinozivikanwa kuti muwanze kukwira mhepo arambe achirema kunoderedza. saka naizvozvo kuderera simba kurwisa kwake. nokukurumidza uye chimiro - asi chete zvinhu acharamba chokuita ndege iri kukosha kurwisa.

No zvishoma kuziva ndiyo nhoroondo pakudzidza mhepo simba pamusoro zvakarurama. Works zvakasikwa izvi zvakaitika kare kare, perondedzero kutanga kunzwisisa 1742. Kuedza rwaiitwa munyika dzakasiyana nedzimwe chimiro mabara uye projectiles. Somugumisiro kutsvakurudza Zvakanyanya Kunaka Panguva Yepamuviri chimiro mabara ndakatsunga uye nhamba musoro uye muswe waro zvikamu tafura zvakagadzirirwa ballistic Maitiro bara vari kutiza.

Gare gare zveBhaibheri yaiitwa maererano bara kubva ayo kumhanya, izvozvo yakaramba kuita chimiro mabara, uyewo nani nzira tsvakurudzo. We vakava kwemasvomhu yemashoko ballistic coefficient - chaiwo kwemasvomhu chishandiso akasikwa. Anoratidza nhamba aerodynamic zvuva mauto uye inertial mauto kuita pamusoro bara.

Nyaya rinotsanangura kuti simba iri mhepo nemishonga, nzira yemaitiro anopiwa runovabvumira kuziva nokukura uye kukura kwomudzimu siyana zvikonzero pamusoro kwakakura nemishonga, zvainoita runoonekwa muminda zvigadzirwa siyana.
