Проектировать ракетные двигатели будут на российском ПО.

🚀 Центр Келдыша провёл семинар по итогам реализации проекта "Внедрение и доработка средств математического моделирования на предприятиях ракетного двигателестроения", в рамках которого были подготовлены к промышленной эксплуатации несколько отечественных программных продуктов.

Была проведена доработка функциональности трёх программных средств:

▪️пакета программ "Логос" (ФГУП "РФЯЦ-ВНИИЭФ");
▪️среды динамического моделирования технических систем SimInTech (ООО "3В Сервис");
▪️и платформы автоматизации расчётов и решения задач оптимизации "DT Seven" (ООО "Датадванс").

Благодаря доработке появились новые возможности расчета движения космических аппаратов по траектории с учетом солнечного и земного излучения, наличия экранно-вакуумной теплоизоляции, решения задач течения двухфазных сред с учётом капиллярных эффектов. В части интеграции обеспечены способы взаимной интеграции отечественных САЕ-средств.

🖥 Также появилась библиотека элементов, которая позволяет создать набор готовых расчетных блоков элементов ракетных двигателей различного типа и реализовать возможность сборки комплексных моделей двигателей различных схем с заложенными расчетами газодинамических и термодинамических процессов.

🏭 Новое ПО, как сообщается, успешно прошло испытания и готово к внедрению в промышленную эксплуатацию на предприятиях отрасли. Разработчики рассчитывают, что внедрение сократит затраты на изготовление материальной части, подготовку экспериментальной базы и время на проведение дорогостоящих огневых испытаний.

Spiking bond yields driving sharp losses in tech stocks

A spike in interest rates since the start of the year has accelerated a rotation out of high-growth technology stocks and into value stocks poised to benefit from a reopening of the economy. The Nasdaq has fallen more than 10% over the past month as the Dow has soared to record highs, with a spike in the 10-year US Treasury yield acting as the main catalyst. It recently surged to a cycle high of more than 1.60% after starting the year below 1%. But according to Jim Paulsen, the Leuthold Group's chief investment strategist, rising interest rates do not represent a long-term threat to the stock market. Paulsen expects the 10-year yield to cross 2% by the end of the year. A spike in interest rates and its impact on the stock market depends on the economic backdrop, according to Paulsen. Rising interest rates amid a strengthening economy "may prove no challenge at all for stocks," Paulsen said.
