American Companies Are Developing Hypersonic Drones Capable of Reaching Mach 5, Five Times the Speed of Sound

Two companies from the United States have formed a partnership to create unmanned aircraft capable of achieving hypersonic speeds – more than five times the speed of sound.

Cummings Aerospace, from Alabama, and ATRX have signed an agreement to develop an affordable and high-performance drone by integrating a turbo-rocket engine with a tested airframe.

The collaboration aims to provide the U.S. military and its allies with a competitive advantage against the advancements of China and Russia in the hypersonic technology sector. The ultimate goal is to increase the stock of ultra-fast military drones for the U.S..

New Generation of Drones and Spaceplanes

The partnership between Cummings Aerospace and ATRX is not limited to hypersonic drones. The companies also plan to develop an unmanned spaceplane designed to take off and land on any conventional runway in the world.

Cummings Aerospace will contribute its Hellhound UAS line, a family of modular aircraft printed in 3D.

Recently, the Hellhound S3 version was tested, reaching 350 miles per hour (about 560 km/h) with half the engine power. During the test, it covered 20 km using only half the available fuel.

The company highlights that the Hellhound’s design allows for adaptations based on customer needs, making it a flexible and scalable solution.

ATRX will provide its Air Turbo (ATR) propulsion system, a high-speed engine capable of reaching Mach 5. According to the company, the ATR consumes 25% less propellant than traditional rocket engines, reducing costs and increasing operational efficiency.

Race for Hypersonic Technology

The United States has significantly increased investments in the development of hypersonic weapons, driven by growing threats from Russia and China.

Earlier this year, the military technology giant Kratos secured a $1.45 billion contract with the Pentagon to create a testing bank specifically for this technology.

One of the challenges for American defense is ensuring accuracy with these weapons, as, unlike the Russian and Chinese versions, U.S. hypersonic missiles will be equipped with conventional warheads – not nuclear ones.

This requires strict control over the trajectory and impact to maximize the efficiency of the armament.

With information from interesting engineering.

Race for Hypersonic Technology

In the cold desert of Ladakh, where it hardly rains, engineer Sonam Wangchuk created the ice stupa, a tower that freezes winter water and stores it for irrigating crops in the spring, a simple engineering feat that mimics nature.

Almost 6,000 residents live concentrated along a single street nearly 9 km long in the interior of Poland. Houses form a continuous row, and behind them, narrow agricultural strips emerge, creating one of the most unusual rural patterns in Europe.

Chinese woman planted trees for decades while sand buried part of her house, received $5,000 from an American in 1999, and helped transform the desert into a forest of 8 million trees in China.

Desert sand, previously discarded for being too smooth for concrete, becomes an ecological brick in the United Arab Emirates, dispensing with Portland cement, curing at room temperature, and attempting to transform dunes useless for construction into raw material for a new arid engineering.

They planted a sea of eucalyptus to produce cellulose, but the monoculture turned into a green desert, dried up springs and rivers, and pushed families out of regions in Minas Gerais and Bahia.

Júlia Pimentel, an 11-year-old from Minas Gerais, independently invented a new formula to calculate the square root using simple addition and multiplication, and her method was published in one of the most important mathematical scientific journals in Brazil.

Described by astronauts as one of the most unlikely natural phenomena on Earth, the Okavango Delta spreads over up to 15,000 square kilometers in the middle of the desert and transforms Botswana into a living labyrinth of channels, islands, and flooded areas.

In the USA, thousands of people are being paid to wash dishes and clean the house with body cameras, every movement turning into data to train robots to imitate humans, in a new “digital gig” that could redefine the future of domestic work.

A 33-year-old from Paraná received a quote of R$ 12,000 just for the structural base of the house, opened tutorials on YouTube, and transformed a family plot into a 200 m² two-story house for about half the price charged by professionals.

It was neither a crash nor abandonment; this retired plane left the airport in parts, crossed Costa Rica on trucks, and ended up becoming a suite in the heights with daily rates exceeding R$ 2,000.

At 22 years old, a young person from Recife creates an artificial intelligence startup with a team barely over 25, serves giants like Bayer and Ipiranga, earns millions without taking a cent from investors, and transforms a young company into a national AI phenomenon.

She panicked when she saw her daughter fall from the crib; years later, she turned the experience into a factory generating R$ 9 million per year.

The invisible danger inside the house: plugging too many devices into the same outlet and spreading extensions throughout the rooms can overload the electrical network, silently heat wires, and turn a common habit into one of the leading causes of house fires.

Goodbye traditional laundry: Roborock launches washer and dryer with super hydrolysis, microbubbles, 99.99% sterilization, low-temperature drying, automatic detergent, app control, and cycles to remove stains, odors, mites, and bacteria from clothes.

It is now possible to generate energy without batteries: new flexible material transforms body heat into electricity and paves the way for more efficient, autonomous, and comfortable wearable devices, with the potential to revolutionize personal electronics in the coming years.
