#RussianUkraineWar ⚡️И о "погоде". Почему падают Герани-5 и прочие филины. Попытка увеличить скорость до 800 км/ч путем установки мощного двигателя наталкивается с одной стороны на волновое сопротивление крыла, и как следствие повышение сопротивления и увеличение тяги двигателя до критических значений с быстрым расходом топлива и сокращением времени и дальности полета. Что делает невозможным движение на скорости 800 км/ч на всем участке полета ЛА по причине наличия крыльев , создающих аэродинамическое качество. С другой стороны и отказаться совсем от крыльев нельзя , ибо для экономии топлива на отдельных участках полета приходится снижать крейсерскую скорость до 400-500 км/ч , что делает полет без крыльев катастрофическим по причине отсутствия аэродинамического качества. Таким образом на таких ЛА конструкция крыла , его длина , толщина и ширина - своего рода компромисс между мощностью двигателя , запасом топлива , массой ЛА , дальностью полета , что делает невозможным полет такого ЛА на скоростях больше 700 км/ч для удовлетворения всех ТТХ. Экземпляры можно разогнать , но путем существенного изменения дальности полета и массы БЧ.
Инженерная истина заключается именно в том, что крыло на скорости 800 км/ч (M ≈ 0,65) работает против ЛА, превращая колоссальный скоростной напор в чистое вредное сопротивление и требуя гигантской тяги, которая «выжирает» топливо за считанные минуты. Но на 450 км/ч без этого же крыла ЛА просто камнем упадет вниз из-за нехватки подъемной силы.
Вся авиационная наука для таких скоростей — это балансирование на лезвии бритвы. Выжать максимальные ТТХ (и дальность, и полезную нагрузку, и скорость) одновременно невозможно. Любая попытка сдвинуть этот баланс в сторону 800 км/ч на всем маршруте превращает ЛА либо в прожорливую ракету с мизерной дальностью, либо требует сделать его настолько тяжелым и дорогим, что теряется сам смысл дешевого беспилотника. Конструкторы вынуждены проектировать планер под «среднюю» крейсерскую скорость (те самые 140–150 м/с), оставляя режим 800 км/ч только как кратковременный форсажный рывок для преодоления зоны ПВО.
Но как раз попытки разогнать аппарат до максимальной скорости приводит к неконтролируемому росту аэродинамического сопротивления, моментальному выгоранию топлива на запредельных режимах работы движка и как следствие - падению до выполнения задачи.
Имперским разработчикам давно бы пора успокоится бесконечно бороться с физикой , но фюрер требует крови и инженеры продолжают свои опасные "эксперименты". Конечно недопустимо недооценивать боевой потенциал аппарата с одной стороны, а с другой развивать в эфире тезис о его возможной "катастрофической для перехвата скорости полета".

There has been a large clash between Russian and Ukrainian special forces in 5th Selishche district of Kherson city after Russian Spetsnaz crossed two groups of soldiers across the Dnipro river.

Ukraine deployed their own special units and killed and captured both groups.

Thick black smoke is observed in Yelets, Russia, where the AO Energiya plant was just attacked. It is now assumed that 3-4 Storm Shadow/SCALP-EG missiles were launched and hit the facility. #Ukraine

[Mike Pence @Mike_Pence]

“Russia invaded Ukraine, committed atrocities in the territories it occupied, and when it failed to force the government to fall or achieve its aims on the battlefield, began targeting civilians, seeking to terrorize the population into accepting Russian domination. The first Trump Administration shook off the Obama Administration’s reticence to assist and admirably sent both weapons and military trainers to help Ukraine.  After the full-scale invasion in 2022, the Biden Administration orchestrated a herculean international effort to assist Ukraine, which the Trump Administration has abandoned.”-@KoriSchake @AEI https://t.co/gIODrZWi99

The most important thing today is that Starlink and Starshield operations have been restored to the speeds we had before the restrictions. The speeds are now where they need to be. The restoration began overnight, and by this morning, speeds were already sufficient. This matters: for our frontline logistics, for defending Ukraine against jet-powered “shaheds.”

I thank all Americans and all our partners who took this seriously and truly helped – members of Congress, senators, all the media, the State Department, and the President. Protecting lives matters.

The “Ozon“ warehouse in Omsk, Russia, is now completely on fire. This was a direct hit.

[Serhii Sternenko @sternenko]

Elon Musk claims that Ukraine allegedly violated Starlink's terms of use and used the system on combat drones.

As someone who was inside the process at the Ministry of Defense, I can say with certainty that this is not true.

In February of this year, whitelists were introduced. Stationary terminals could be registered by both military personnel and civilians.
But for any satellite terminal to work while on the move, it had to be added to a special list and connected to the military Starshield system. Otherwise, no satellite communication terminals in Ukraine would work.

In other words, using civilian Starlink for drone missions was technically impossible. All drone missions that required satellite communication could only be carried out using Starshield.

We are very grateful to the United States and SpaceX for access to critically important satellite communications. Ukraine did not violate the terms of use.

You misspelled “Russia”.

[OSINTtechnical @Osinttechnical]

Ukrainian forces carried out a Storm Shadow cruise missile strike tonight on Russia's Proton plant in Oryol, a producer of electronics for ballistic missiles.

Comes days after the UK supplied Ukraine with a new package of Storm Shadows to hunt down Russian missile capabilities.

[Senator Mark Kelly @SenMarkKelly]

In what world is Putin a "humanitarian?” He's assassinated political rivals and journalists, bombed hospitals, and started a war that has intentionally killed tens of thousands of innocent people, including women and children. He's a war criminal.

[Senator Thom Tillis @SenThomTillis]

WTF, Steve? Look up the definition of “humanitarian.” What an embarrassing and outrageous thing to say. You should go back to Ukraine and ask the families of the children Putin has kidnapped and murdered whether they agree your friend Putin is a “humanitarian.”

Manifestare è un diritto, devastare le nostre città no. Ecco le misure che abbiamo approvato per contrastare la violenza e tutelare la sicurezza dei cittadini.

[Volodymyr Zelenskyy / Володимир Зеленський @ZelenskyyUa]

Of course, we are not losing this war. But we are losing people. Because of the Russian attacks, we're losing people and time. It's such a pity, because our children don't have a real life and childhood. Not only children, but all people. That's why we need to end this war as quickly as possible. I hope that our partners, Americans and Europeans, will help us. God bless, our strong soldiers stay strong on the battlefield. It helps me stay strong during any kind of negotiations.

Trump says that Russia “frankly, has been fine on Ukraine. They haven't been doing much."

Notably, a Russian strike on a park in Ukraine's Kharkiv Oblast today killed six people, including three children.

[Radosław Sikorski 🇵🇱🇪🇺 @sikorskiradek]

Wow.

[Volodymyr Zelenskyy / Володимир Зеленський @ZelenskyyUa]

A horrific Russian strike in the Kharkiv region. A “shahed” struck people directly – in a park near an ordinary café. Pure atrocity. Six people were killed, including children. A little girl was killed in a stroller – her name was Angelina, she was just over a year old, born in August 2025… Her mother’s name was Inna. She died in the hospital… Another girl who was killed was 11 years old. My condolences to their families and loved ones. Another 14 people were injured, including six more children.

I am grateful to everyone who supports Ukraine under these circumstances and helps us shoot down “shaheds,” shoot down missiles, and stop Russian assaults. These are horrific photos, but behind them are shattered lives and the truth about this war. Lives must be protected. Ukraine needs air defense. You can't think about making money with Russia as long as it continues its asinine war. We ask that sanctions on Russia stay in place as long as the killings continue. We ask America to be strong, and we ask it to apply the Lindsey Graham law. We ask Europe to continue its support. We ask that everything possible be done to bring peace and guarantee security. Ukraine wants peace. It is Russia that has insisted on continuing the killing all this time. The world has enough strength to stop the war. That strength must finally be used – against the murderers.

[Hillary Clinton @HillaryClinton]

Ten years ago today.

In just the last few days: Trump made a deal for the U.S. to buy Russian diesel, an economic lifeline for Putin; he and Elon Musk blamed each other for an order that slowed down Starlink satellite connectivity over Ukraine, hampering the country's defenses during a devastating Russian attack; and Trump waived sanctions on Russia that Congress, led by his late friend Lindsey Graham, had pushed for.

Now, Putin has proposed a summit with Trump and Xi to decide Ukraine’s fate for them, bulldoze a century of international cooperation, and frame Russia as an equal to the U.S. and China.

We’ll see if Putin’s puppet continues to dance on his strings.

[Rep. Brian Fitzpatrick 🇺🇸 @RepBrianFitz]

I will be speaking with Ukrainian President Volodymyr Zelenskyy and his team this week to discuss Starshield, sanctions, and other matters pertaining to the defense of our strong ally, Ukraine. I will be assuring President Zelenskyy that anyone who attempts to limit the use of Starshield for Ukraine will be fully investigated and will be held fully accountable, to include public congressional oversight hearings, and immediate harsh and punitive budget cuts to any responsible agency or agency head.

Congress will unequivocally reaffirm that Ukraine is an indispensable ally to the United States, that Russia is a self-declared enemy of the United States, and that the United States will 100% support and defend the people of Ukraine in their fight for their own freedom against this brutal, illegal, and unprovoked Russian invasion.

The United States must provide any and all defensive equipment that Ukraine needs to defend itself. The United States must not import a single drop of Russian oil. Sanctions against the Russian regime must be harsher and stronger than they’ve ever been before. Each and every one of these items will be brought to the House Floor—and each and every one of these items will pass on the House Floor by an overwhelming margin.

This is, after all, what Ronald Reagan would do. And this is what we will do now. Ukraine can, and will, defeat Russia. #PeaceThroughStrength
