1. ОПИСАНИЕ ЭКСПЕРИМЕНТАЛЬНОГО СТЕНДА СВС-2
Специализированная АТД СВС-2 более других приспособлена для исследования
моделей ВЗ. Она имеет широкий диапазон скоростей М=0,2-6. Многие ее
технологические особенности повторяются в трубах ТПД, СВС-1, ТССМ.
1.1 Принципиальная схема и параметры аэродинамической трубы
Главной особенностью СВС-2 (Рис. 1) является то, что она оборудована
уникальным регулируемым многорежимным соплом 500х516
