The SR-71 Blackbird converts supersonic air to subsonic speeds using a movable, conical "spike" in the engine inlet that generates a series of shock waves, slowing air from over Mach 3 to roughly Mach 0.4 before it reaches the compressor. This process, crucial for the J58 engine, transforms high-speed,...

During an engine run, massive amounts of air are pulled into the engine, creating strong suction at the inlet. The rapidly spinning fan accelerates the airflow, increasing its speed and changing the pressure around the engine. This pressure difference causes surrounding air, dust, and moisture to bend and flow toward the inlet. Even while stationary, the engine generates intense wind forces that show just how much air it moves. 📸 by ig/xtreme_aviation

In today’s episode of “Behind Every Takeoff”, ATA 21 B787 Primary & secondary heat exchangers(HX) cleaning The HXs cool down hot compressed air from from the Cabin Air Compressors(CAC) before going into the Air Cycle Machine(ACM). Ambient air cools the HXs through the ram air inlet doors which may introduce debri such as paper, plastic, & built up dirt/grime which reduce performance. We accomplish an inspection and a cleaning using an approved solvent/water mixture wash to the HXs. With laxjettech

I'd like to take a second to discuss what it means for a storm to be a Category 5. It's a beautiful, mesmerizing, terrifying and awe-inspiring pageant of power and elegance. It's the atmosphere at its most dynamic, raw and extreme. The hurricane has to have an absolutely perfect, undisturbed balance. It's an extremely rare feat. A Category 5 is like a spinning top whirring on a table; even the slightest jiggle can knock it off-kilter – like bumping the table. There must be virtually no shear, or changing winds with height. The upper-level winds around the system must be relatively calm. It's incredible to think that the planet's most furious storms are born out of an abundance of calm. The waters must be exceptionally warm – upwards of 86 degrees – to be replete with "oceanic heat content," or heat energy for the hurricane to draw upon. The warm waters heat and moisten the air above. That air rushes into the building hurricane. As air nears the center of the storm, it expands due to the hurricane's low pressure. That expansion releases heat energy to the environment, encouraging air to rise and powering the storm. In theory, that air parcel (pocket) should cool, but it doesn't. Why? It's still being heated by the oceans below. The ocean is constantly re-heating the lower atmosphere – and energizing the storm – at the exact same rate the air is releasing heat energy into the storm. Most of the moisture in the air condenses and produces rain, releasing even more "latent heat" to the environment. Near the hurricane's center, there's a lot of heat energy. So much so that the air rises, as if in a chimney. That rising air literally lifts air up and away from the surface. There's literally less air, and therefore less air weight, or *pressure*, at the center of the storm. Most Category 5 hurricanes are "missing" about 8-10 percent of the air from the middle. It's that deficit of air that behaves like a vacuum of sorts. Air from outside the storm rushes in to fill the void, like water spiraling into a sink drain. The greater the deficit, the faster the winds. The wind increases exponentially closer to the center of the storm; Category 5 hurricanes have winds over 157 mph. So why doesn't the eye, with the "missing" air, just "fill in?" Because the hurricane is rotating so furiously! The air is flung outwards by the "centrifugal force" at the exact same rate it's being pulled inwards by the "pressure gradient force." The air can never fully reach the eye – and instead it swirls around and around, like water perpetually sloshing around the edges of a toilet. We call that "cyclostrophic balance." Thus, the eye doesn't fill in. The storm charges on. And – until the system is torn apart by disruptive upper-level winds or moves over cooler waters/land – it continues.

A pickle jar can function as a tiny jet engine. The setup is simple: a glass jar with a small hole in the lid holds a volatile fuel like methanol, which evaporates to create a fuel and air mixture inside. A flame brought to the hole ignites it, and the cycle begins. Here is what happens in each pulse. Combustion sends a sharp pressure spike through the jar, forcing hot gas out the lid hole as thrust. The escaping gas creates a brief partial vacuum inside, which pulls fresh air back in through the same hole. Residual heat ignites the new mixture automatically, and the cycle repeats dozens to hundreds of times per second. The jar and hole act as a resonant cavity, which is why it pulses instead of burning steadily. A single opening cannot handle exhaust and intake at the same time, so the system locks into a natural rhythm. It produces almost no real thrust, but it is a clear window into how actual pulsejet engines work, and the physics on display are the same ones used in real aerospace propulsion. Follow for more!

The F-16’s afterburner boosts thrust by injecting additional fuel into the exhaust stream after the gases have already passed through the turbine. This creates a second stage of combustion that dramatically increases engine power. In normal operation, the engine compresses incoming air, burns it in the main combustion chamber, and uses the resulting energy to drive the turbine. The hot, high-speed exhaust then flows into the afterburner section, which contains flame holders—metal structures designed to stabilize the flame in the fast-moving airflow. When the pilot engages the afterburner, fuel is sprayed into this exhaust stream and ignites almost instantly. Because the exhaust still contains unused oxygen, the added fuel burns intensely, causing the gases to expand and exit the nozzle at much higher velocity. To maintain smooth airflow and prevent excessive pressure buildup, a variable-area nozzle opens wider. The outcome is a massive thrust increase—often 50% or more—accompanied by the bright, fiery plume that appears when the afterburner is active. 🔥✈️ 📸 by ig/fighteraircraft

Everyone remembers the SR-71... but almost everyone forgot the aircraft that made it possible. The Lockheed A-12 Oxcart, developed by Lockheed's legendary Skunk Works under the codename "Archangel," first flew in 1962 for the CIA as a top-secret reconnaissance aircraft. Built almost entirely from titanium, it could cruise above Mach 3 at altitudes over 85,000 ft (26 km)—fast and high enough to outrun enemy interceptors and surface-to-air missiles. This is the legendary spy plane taxiing out before unleashing its raw power on takeoff. The grandfather of the Blackbird still looks futuristic over 60 years later.

As the CFM LEAP engine shuts down, you can hear the distinctive “whoosh” sound followed by a gush of air. That is the Reverse Bleed System (RBS) at work. During normal operation, a significant amount of fuel remains unpurged in the system after engine shutdown. This residual fuel, located near or within the hot section, vaporizes due to high temperatures and deposits carbon (coke) on the fuel nozzles. Over time, nozzle coking leads to several operational and maintenance issues, including loss of thrust, reduced engine efficiency due to incomplete combustion, accelerated deterioration of hot-section components (combustor and High-Pressure Turbine), engine start failures, potential engine stalls, and increased unscheduled engine removals. The Reverse Bleed System (RBS) prevents fuel nozzle coking by automatically introducing cool air from the core compartment into the engine core flowpath after shutdown. This effectively lowers the fuel nozzle temperature below the coking threshold. RBS can operate for a maximum of 1 hour, and its effectiveness depends on ambient conditions (especially ambient temperature) and the total duration it runs. The last flight of the day contributes the most to fuel nozzle coke accumulation because of the extended dwell time at the gate. By actively managing post-shutdown thermal conditions, RBS significantly reduces coking-related problems, improves engine reliability, and lowers long-term maintenance costs. Now, also coming soon to the CFM56

🚨Breaking News… history just changed over Tehran in EPIC AIR BATTLE. Today, March 4, 2026, the sky over Iran witnessed something that had never happened before in the history of modern air combat. An Israeli F-35I “Adir” stealth fighter engaged and destroyed an Iranian Air Force Yakovlev Yak-130. The aircraft was completely eliminated in an air-to-air engagement over Tehran. This was not a drone strike. Not a missile launched from the ground. Not a proxy operation. This was a manned stealth fighter eliminating another aircraft in the skies over Iran. And it marks a historic milestone. This engagement is now being reported as the first confirmed air-to-air kill ever achieved by the F-35 platform anywhere in the world. Let that sink in for a moment. The most advanced fighter jet ever deployed in combat… designed with stealth geometry, sensor fusion, and battlefield awareness beyond anything that came before it… has now officially recorded its first aerial victory. The Iranian aircraft destroyed was a Yakovlev Yak-130, a Russian-built advanced trainer and light attack jet used by the Iranian Air Force. This also represents something else historically significant. It is the first Israeli manned air-to-air combat engagement in roughly four decades. Forty years. For decades Israeli pilots have dominated the skies through deterrence, technology, and overwhelming air superiority. But today that dominance translated into direct aerial combat once again. The Israel Defense Forces have officially confirmed the engagement. Multiple defense outlets and international military analysts are already reporting the event. This moment will likely be studied in military academies around the world for years to come. The first air-to-air victory of the American F-35 era. A stealth fighter engaging in real combat… and winning. History just unfolded over Tehran. #SilentMajoritySpeaks #AStoneGroove

It's always fascinating to watch the outflow valve (OFV) close during takeoff. This marks the beginning of the aircraft’s pre-pressurisation cycle. While it does provide a smoother transition to pressurised flight and improves passenger comfort, its main purpose goes beyond that. The primary reason for closing the outflow valve at takeoff is to prevent a slight pressure bump that occurs during aircraft rotation. At high angles of attack, an air cushion effect forms over the aft outflow valve, which can cause a momentary reverse airflow - potentially pushing air back into the cabin through the OFV. This pre-pressurization prevents FOD from being blown into the cabin, and this is also the reason the airplane lands with a slightly pressurized cabin. #FunFact

City of Harare admits air can trigger water meter charges The City of Harare and Helcraw Water say prepaid water meters work the same way as ordinary water meters. They say the meters are not faulty. According to the statement, when there is air trapped in water pipes after events like burst pipes, repairs, or when the water supply is restored, that air can pass through water meters and cause them to record water use even though mostly air is flowing. The city says this is a known challenge that affects both prepaid and conventional water meters, and that current technology cannot always tell the difference between water and large amounts of pressurised air. Residents are advised to close their taps immediately if only air is coming out and report the problem to the City of Harare or Helcraw Water so technicians can fix it. The city also says it is installing air release and pressure relief valves across the water network to reduce trapped air, improve the water system, and minimise incorrect meter readings caused by air. It says it remains committed to providing a reliable and transparent water supply.

Everyone is bracing for oil to be inflationary. History says the opposite. An oil shock is recessionary. A spike at the pump hits prices right away, but with a weak labor market nobody can absorb an extra 100 or 150 dollars a month. So they pull spending from everywhere else, and businesses hit with higher diesel do the same. That is demand destruction. Spending falls, the price of everything other than oil drops, and eventually oil falls too. So the shock is a short inflation spike that reverses almost immediately. The real outcome is not inflation. It is recession. The danger is a central bank hiking into the spike because it looks inflationary, then being forced to reverse. Trichet's ECB did exactly that in 2008.

Had the honor of launching the weather balloon for upper air data collection in NOAA Boise NWS Boise. A radiosonde is a battery-powered instrument package attached to a weather balloon that measures atmospheric pressure, temperature, humidity, and wind speed as it ascends. Transmitting real-time data via radio to ground stations. The upper air data is crucial for input into weather models and useful for predicting severe damal dumeels. The radiosonde flight can last for more than two hours. During this time, the balloon can ascend to heights exceeding 35 km and drift over 200 km from the launch point. Throughout the journey, the radiosonde experiences extreme atmospheric conditions, including temperatures as low as -92°C and air pressures that are only a fraction of those at Earth’s surface. When the balloon has expanded beyond its elastic limit (20-25 feet in diameter) and bursts, the radiosonde returns to Earth via a small parachute. This slows its descent, minimizing the danger to life and property.

In continuous cable manufacturing, compressed air performance must keep pace with constantly changing production demands. In a leading cable manufacturing facility, compressed air plays a critical role across extrusion controls, air-wipe drying, cleaning, and material handling systems, making pressure stability and compressor reliability essential for consistent product quality and high uptime. At the plant, a 75 kW fixed-speed compressor reliably met base air requirements. However, variations in production loads, line speeds, and process cycles led to frequent demand fluctuations, resulting in repeated compressor cycling, higher energy consumption, and pressure instability across the system. With the deployment of ELGi’s DEMAND=MATCH System, performance was evaluated under actual operating conditions by comparing operations with and without DEMAND=MATCH. The results were clearly validated. • 11.1% reduction in average power consumption (from 69.9 kWh to 62.1 kWh per hour) • Approximately 1,489 units of energy saved over just eight days of actual running • Reduced load cycling, leading to improved pressure stability and lower mechanical stress on the compressor This deployment demonstrates how intelligent airflow control can deliver measurable gains in energy efficiency, system stability, and operational reliability, all critical in a continuous manufacturing environment. A strong example of how aligning compressed air delivery with real-time demand can drive sustainable performance improvements on the shopfloor.

About Patriot Air Defense Systems Another video where three PAC-3 missiles from the Patriot air defense system, launched at an Iranian missile, fail to hit their target. The missile somehow evades them and manages to reach its target. The cost of a single PAC-3 missile is a million US dollars. The expenditure is so high that they'll only last for a couple of weeks, and that's it. - Slavyangrad
