Abstract
1. Способ создания рабочего потока в аэродинамической трубе по авт.св. № 1496450, отличающийся тем, что, с целью расширения экспериментальных возможностей путем увеличения скорости кислородсодержащих потоков, в рабочий газ дополнительно подают закись азота, а подачу сжатого гелия осуществляют до достижения средней температуры смеси в форкамере величины 600-1300 K, при этом перед вытеснением смеси через сопло ее выдерживают в форкамере в течение 0,001-1 с до инициирования реакции разложения.2. Способ по п.1, отличающийся тем, что, с целью моделирования натурных условий взаимодействия рабочего потока с исследуемым объектом путем воспроизведения реального состава воздуха по кислороду и углекислому газу, подачу закиси азота и метана в форкамеру осуществляют при мольных долях, равных, соответственно, 0,527 и 0,00414.1. The way to create a workflow in a wind tunnel on the author.St. No. 1496450, characterized in that, in order to expand the experimental capabilities by increasing the rate of oxygen-containing streams, nitrous oxide is additionally supplied to the working gas, and compressed helium is fed until the average temperature of the mixture in the prechamber is 600-1300 K, while displacing the mixture through the nozzle, it is kept in the prechamber for 0.001-1 s before initiating the decomposition reaction. The method according to claim 1, characterized in that, in order to simulate the natural conditions of the interaction of the working stream with the object under investigation by reproducing the actual composition of air in oxygen and carbon dioxide, nitrous oxide and methane are supplied to the prechamber at mole fractions equal to 0.527, respectively and 0.00414.
