Raketalar dinamikasi \u2014 reaktiv dvigatelli uchish apparatlari harakatini o’rganish bilan shug’ullanadigan fan. Raketalar dinamikasining nazariy asoslari 19-asr oxiri, 20-asr boshlarida yaratildi, 20-asr 40-yillari oxiridan jadal rivojlana boshladi. Bo’limlari: 1) raketalarning og’irlik markazi harakatini o’rganish; bunda traektoriyalarga oid masalalar nazariyasi yaratiladi; 2) raketalar harakatini og\u2019irlik markaziga nisbatan o’rganish; bunda kosmik kemalarni kosmosda tutashtirish, raketalarni boshqarish, mo’ljalga to’g’rilash va boshqa masalalar hal qilinadi; 3) eksperimental Raketalar dinamikasi; bunda raketalar harakatini tadqiq qilishning eksperimental usullari o’rganiladi. Raketalar dinamikasida optik va radiotexnik asboblar, kompyuterlar qo’llaniladi, ehtimoliy jarayonlar nazariyasidan foydalaniladi. Raketalar dinamikasining asosiy vazifalaridan biri \u2014 dvigateli ishlab turgan raketalarning harakat qonunlarini o’rganish. Raketa uchayotganda yonilg’i yonishi tufayli massasi ancha kamayadi. Masalan, bir bosqichli raketalar tezlik olish (start) paytida dastlabki og’irligining 90% ini yo’qotadi. Dvigateli ishlab turgan raketalarning harakat qonunlari o’zgaruvchan massali jismlar mexanikasi tenglamalari orqali ifodalanadi.<\/p>\n","protected":false},"excerpt":{"rendered":"
