Meet the Bell 360, the latest rival to the Sikorsky Raider X.
Meet the Bell 360, a new challenger to the Sikorsky Raider X. Bell, the world’s most recognizable commercial helicopter manufacturer, has created a new combat helicopter.
Bell, the world’s most recognized commercial helicopter manufacturer, has developed a new combat helicopter that will compete with the Sikorsky Raider X chopper.
The first prototype of the Bell 360 invictus, which means unconquerable in Latin, was recently shown. After engine development, the helicopter is ready for testing.
The Invictus is a conventional helicopter with fast speed and low cost that was initially introduced in 2019. The helicopter, like many modern attack helicopters, has a tandem seat structure. The design is similar to the Tiger helicopter from Airbus and the Light combat helicopter from HAL India. However, the bell has an unusual design with a low radar cross section area, which is not the primary design aim.
It has four 40-foot-diameter rotor blades, an active horizontal stabiliser, and a slanted and shrouded tail rotor positioned below the shrouded rotor hub. Missiles are launched from launchers that are integrated. The aircraft appears aerodynamic, and the rotator is covered for improved air flow around the spin. The rotor diameter is determined by US Army specifications, which specify the maximum diameter for FARA contenders in order for the rotorcraft to fit between buildings on future battlefields.

The Bell helicopter prototype currently lacks a functional engine. However, the General Electric T901 engine will be installed shortly. Following the construction of the engine, this helicopter will be tested at a speed of 180 knots or 330 kilometres per hour.
Pratt & Whitney also manufactures the Auxiliary power units system for helicopters. It can be used as a backup power source for the systems
This helicopter will be outfitted with advanced armaments such as the AGM 114 Hellfire, AGM 179 JAGM missiles of the XM 915 – 20 mm auto gun, and two launchers with four missiles.
The US Army requires a cruising speed of more than 180 knots (330 km/h), which the 360 is designed to meet; the 525 rotor system has been tested to achieve 200 knots (370 km/h). At moderate to high speeds, the stub wings are designed to create lift equivalent to around 50% of the aircraft’s weight. With at least 90 minutes on station, the combat radius will be 135 nautical miles (250 km). Fly-by-wire control will be used.

Can Airline Seat Cushions Be Used As Life Jackets?
In the event of an aircraft ditching into water, there’s a common question: Can aircraft seats serve as an alternative to life jackets for flotation? The answer lies in understanding their respective functions.
While seat cushions can provide some buoyancy in water, they are not intended nor certified to function as life jackets. Their primary purpose is to offer cushioning for passengers during flight. On the other hand, life jackets are meticulously engineered to keep individuals afloat in water, equipped with buoyancy materials, secure straps, and reflective elements for visibility. They offer numerous advantages over mere cushions.
While a seat cushion might offer temporary assistance in staying afloat, it’s not a dependable substitute for a proper life jacket during an emergency. It’s crucial to utilize approved safety equipment when near bodies of water. A life jacket, designed to keep a person buoyant for extended periods, offers the rigidity needed for prolonged flotation and allows for easy movement of the arms to navigate effectively.
What fabric is used in aircraft seats?
Seats are meticulously designed to fulfill multiple purposes, ensuring passenger comfort, safety, and protection from unforeseen circumstances like fires and accidents. A typical design incorporates an aluminum frame with blocks of polyurethane foam affixed to it. Additionally, a layer of fire-resistant fabric, such as Kevlar or Nomex, is often applied over this framework, topped with a layer of cloth or leather.
Leather seats, while luxurious, are more expensive compared to traditional cloth seats. The majority of fabrics used in seat upholstery contain at least 90% wool fiber, with the remainder typically consisting of polyamide (nylon). Wool stands out as the primary fiber chosen for commercial airline seating fabric due to its desirable properties and suitability for such applications.
What is the lightest economy seat?
In recent times, airlines have been downsizing seat dimensions to accommodate more passengers, resulting in reduced cushion length and leg space. This contrasts with earlier times when airlines offered more generously cushioned seats and ample amenities.
According to Recaro Seats Company, their SL3710 model represents the lightest economy class seat available, weighing in at a mere 8 kg (17.6 lb.), setting a new standard in aircraft seating.
For individuals weighing more than 350 pounds, fitting into a standard economy-class seat can be a challenge due to the narrower dimensions. Economy seats, also referred to as “coach,” “standard,” or “main cabin” seats, typically range from about 40 to 48 centimeters in width, further emphasizing the need for more accommodating seating options.
