Fokker V.24

The Fokker V.24 was a prototype single-seat biplane fighter aircraft developed by the Fokker-Flugzeugwerke in Schwerin, Germany, during World War I. Designed by chief engineer Reinhold Platz, it formed part of Fokker's experimental V-series, which emphasized innovative structural techniques such as a welded steel-tube fuselage for superior strength and rigidity compared to traditional wood-and-wire constructions. Built in early 1918 as factory number 2612, the V.24 participated in the German Idflieg's fighter evaluation trials at Adlershof, where it served as a testbed for advanced powerplants amid efforts to counter Allied aerial dominance.^[1]^[2]^[3] Initially equipped with a 240 hp (180 kW) Benz Bz.IVü six-cylinder inline water-cooled engine, the V.24 underwent its acceptance trials on April 24, 1918, piloted by Fokker test pilot Rudolf 'Grosse' Otto. In June 1918, the prototype was re-engined with a 185 hp (138 kW) BMW IIIa inline engine for additional evaluations, revealing excellent rate of climb—reaching 2,000 meters in approximately 4 minutes—and strong maneuverability at high altitudes. These traits, combined with the airframe's inherent structural integrity, highlighted its potential for air superiority roles, though its high wing loading limited overall handling in some aspects.^[1]^[4]^[5] Only a single V.24 prototype was constructed, and it did not proceed to production due to the war's end and prioritization of established designs. Nonetheless, its testing influenced the refinement of the production Fokker D.VII fighter, particularly by validating the BMW IIIa integration that led to the high-performance D.VIIF variant deployed in late 1918. The V.24's contributions underscored Fokker's rapid iteration on engine-airframe compatibility, shaping post-war civilian and military derivatives in the V-series lineage.^[4]^[6]^[7]

Mil V-24

The Mil V-24 was an experimental helicopter prototype developed by the Mil Moscow Helicopter Plant in the late 1960s as a multi-role combat aircraft intended to combine gunship capabilities with troop transport functions.^[8]^[9] This design emerged from Soviet efforts to create a dedicated fire support helicopter, drawing on components from the Mi-8 transport helicopter while incorporating a new armored fuselage for enhanced survivability in combat environments.^[10] The V-24's development was approved in 1967 following initial mockup work in 1966, reflecting the Soviet Union's push for advanced rotary-wing assets during the Cold War era.^[8] The first V-24 prototype rolled out in June 1969 and conducted its initial tethered hover tests shortly thereafter, followed by the first free flight on September 19, 1969, piloted by test pilot Herman V. Alferov.^[11] Powered by two Isotov TV2-117 turboshaft engines each delivering 1,700 shp, the prototype was optimized for close air support missions, including the destruction of armored targets, while capable of carrying up to eight troops in its cabin.^[10]^[8] Key design innovations included an armored cockpit for crew protection, stub wings with hardpoints for mounting weapons such as anti-tank missiles, and a five-blade main rotor system paired with a three-blade tail rotor to improve lift and maneuverability.^[11]^[10] These features allowed the V-24 to support ground forces aggressively, blending transport and attack roles in a single platform.^[9] A total of three V-24 prototypes were constructed to refine the design, addressing early challenges such as excessive weight and rotor efficiency through measures like a slimmer fuselage profile and optimized rotor head modifications.^[8]^[9] These iterations focused on reducing overall mass to enhance performance without compromising the helicopter's combat utility, including its retractable tricycle landing gear and anhedral stub wings that alleviated rotor loading at high speeds.^[10] The V-24 prototypes laid the groundwork for the production Mi-24 "Hind" series, which entered Soviet service in the 1970s and became a cornerstone of attack helicopter operations.^[8]

Softex-Aero V-24

The Softex-Aero V-24 is a four-seat twin-engine light aircraft developed by the Ukrainian company Softex-Aero since the early 2010s, primarily for general aviation and personal transport applications.^[12]^[13] The airframe utilizes composite materials to achieve a lightweight structure, enhancing efficiency and performance for civilian use.^[14]^[15] Development began with the first flight of a prototype in 2012, leading to the receipt of a Ukrainian type certificate in October 2014 for the configuration powered by two Rotax 912S engines.^[13] The aircraft features a T-tailed, low-wing monoplane design with pusher propellers mounted on the wings, retractable tricycle landing gear, and a whole-aircraft ballistic parachute system—specifically the Galaxy GRS—for emergency recovery and enhanced safety.^[13]^[16] It accommodates one pilot and three passengers, with a focus on comfort through customizable interiors and modern avionics including autopilot options.^[13]^[14] Powered by two 100 hp (74 kW) Rotax 912S engines (with the turbocharged Rotax 914 as an alternative for higher-altitude performance), the V-24 is intended for medium-haul civilian flights.^[13]^[15] Key performance specifications include a maximum speed of 352 km/h, a cruise speed of 250 km/h, and a range of up to 1,500 km with full fuel capacity of 260 liters.^[13]^[17] The prototype was first publicly displayed in 2014 at events such as the Middle East Business Aviation (MEBA) exhibition, marking an early showcase of Ukrainian advancements in composite light aircraft design.^[18]^[19] Variants include the V-24-I, a standard four-seater configuration optimized for personal use, and the V-24L, which offers extended range capabilities for longer medium-haul operations.^[13]^[17] As of 2025, the V-24 continues to be manufactured and used in Ukraine for multi-purpose applications.^[20] This project contributes to modern Ukrainian aviation development by promoting innovative, safety-focused light aircraft for non-military markets.^[14]

Technology

V24 engine

A V24 engine is a 24-cylinder internal combustion piston engine featuring two banks of 12 cylinders each, arranged in a V configuration around a common crankshaft, often at a 60- to 90-degree angle between banks. This layout allows for high power output in applications requiring substantial propulsion, such as aviation, marine vessels, heavy trucks, and industrial generators, where space constraints permit the engine's elongated design. Unlike more common V12 engines, which balance compactness with power for passenger vehicles, the V24's greater cylinder count enables superior torque and horsepower density for large-displacement needs, though at the cost of increased overall length compared to inline configurations.^[21] Historical development of V24 engines occurred primarily in the 20th century, with examples spanning aviation prototypes and diesel powerplants for heavy-duty uses. In the 1930s, the Fiat AS.6 served as an early aviation benchmark, a liquid-cooled V24 with approximately 50 liters displacement, delivering up to 3,100 horsepower at 3,300 rpm through dual superchargers and a tandem propeller drive system; it powered the Macchi M.C.72 seaplane to a world speed record of 709 km/h in 1934. Similarly, the Allison V-3420, developed in 1937 as an experimental liquid-cooled aircraft engine with 56.1 liters displacement, achieved 2,300 horsepower at takeoff (3,000 rpm) and was tested in prototypes like the Douglas XB-19 bomber and Fisher XP-75 fighter, though production was limited to 157 units due to the rise of turbojet technology by World War II. Post-World War II, diesel V24s emerged for non-aviation roles, exemplified by the Detroit Diesel Series 71 24V71, a two-stroke engine with 27.9 liters displacement developed in the 1960s for generators and marine applications, rated at 1,550 to 2,000 horsepower at 1,800 rpm in standard configurations, with some tuned variants exceeding 3,000 horsepower for specialized trucks like the Thor Peterbilt 359. A notable automotive prototype was the Mercedes-Benz V24 concept from the late 1990s, intended for Maybach luxury vehicles, featuring a 12-liter gasoline displacement projected to produce around 800 horsepower and 1,200 Nm of torque, but it remained undeveloped due to feasibility concerns.^[22]^[21]^[23]^[24] The V24 configuration offers advantages in power density, enabling large displacements to generate exceptional output—such as the Fiat AS.6's 3,100 horsepower from its 50-liter setup—for demanding propulsion without excessive length relative to inline-24 alternatives. However, disadvantages include extreme physical dimensions (often over 3 meters long), substantial weight (e.g., the Allison V-3420 exceeded 1,500 kg dry), and mechanical complexity from managing 24 cylinders, leading to higher maintenance needs and reliability challenges, as seen in the Allison's dual-crankshaft iterations to mitigate vibration. These factors restricted V24 engines to specialized, non-automotive applications like aircraft prototypes, marine drives, and generators, with no widespread production for passenger cars owing to severe packaging issues in vehicle chassis. Production was limited to short runs or concepts throughout the 20th century, as advancing technologies like turbojets and efficient V8/V12 diesels rendered them obsolete for most roles.^[22]^[21]^[25]

ITU-T V.24

ITU-T Recommendation V.24, last revised in February 2000, provides the international standard for defining interchange circuits at the interface between data terminal equipment (DTE), such as computers, and data circuit-terminating equipment (DCE), such as modems.^[26] It specifies the functional and electrical signaling characteristics for over 30 interchange circuits used in serial binary data transmission, supporting both asynchronous and synchronous operations.^[26] These circuits enable reliable data exchange in telecommunications systems, including control signals for handshaking and timing.^[26] Key interchange circuits include circuit 101 (protective ground), circuit 102 (signal ground or common return, providing a reference potential for unbalanced circuits), circuit 103 (transmitted data or TXD, carrying serial data from DTE to DCE), circuit 104 (received data or RXD, delivering data from DCE to DTE), and circuit 105 (request to send or RTS, used by DTE to signal readiness to transmit).^[27] Circuit 106 (clear to send or CTS) allows the DCE to indicate availability for reception.^[27] These circuits are typically implemented on a 25-pin D-subminiature connector, with additional circuits in the 140 series for synchronous operations and 200 series for automatic calling equipment.^[26] The standard employs single-ended signaling, suitable for unbalanced interfaces.^[28] V.24 supports data rates up to 115 kbit/s over distances of up to 15 meters, making it appropriate for short-range connections in legacy systems.^[26] It complements Recommendation V.28, which defines the electrical characteristics for unbalanced single-ended circuits, as well as V.10 and V.11 for balanced differential versions. Widely adopted since the 1960s for serial ports in computers, modems, and industrial control equipment, V.24 serves as the functional counterpart to the U.S. EIA RS-232 standard.^[29]

Media

V24 (The Boys)

In the universe of the Amazon Prime Video series The Boys, V24, also known as Temp V or Compound V24, is a green injectable serum developed by Vought International as a modified version of the original Compound V.^[30]^[31] This substance grants ordinary humans—referred to as "non-supes"—temporary superhuman abilities for precisely 24 hours per dose, such as super strength, laser vision, teleportation, and invulnerability.^[30]^[32] Unlike the permanent effects of standard Compound V, which are hereditary and lifelong when administered to infants, V24 provides non-hereditary, time-limited enhancements designed initially for military use, such as empowering soldiers.^[30]^[31] Introduced in season 3 of The Boys (2022), V24 plays a pivotal role in the plot when Billy Butcher steals a supply from Queen Maeve and distributes it to members of The Boys to combat supes like Homelander and Soldier Boy.^[30]^[32] Each dose costs $2 million on the black market, underscoring Vought's corporate profiteering.^[30] However, the serum is highly unstable and addictive, leading to severe side effects including vomiting of green blood, discharge of black goo from the ears, sweating, irritability, organ failure, and rapid tumor growth; repeated use beyond three doses proves fatal, often within 12-18 months, as seen in Butcher's deteriorating health.^[33]^[32] These risks heighten internal conflicts within The Boys, particularly as Butcher's obsession with the drug exacerbates his moral decline.^[30] V24 is part of the shared universe explored in the spin-off series Gen V (2023), which delves into broader variations of Vought's Compound V lineage, such as the immortal V1 formula, while maintaining themes of the serum's corrupting influence and corporate control over superhuman enhancements.^[34]^[33]^[31]

Visegrád 24

Visegrád 24 is a digital media outlet and social media account that aggregates and curates news with a focus on politics, current events, history, and culture from a conservative perspective. Launched in January 2020 as an X (formerly Twitter) account under the handle @visegrad24, it rapidly grew to over 1.4 million followers by November 2025, establishing itself as a prominent voice in international news dissemination. The platform expanded into a full website, visegrad24.com, which emphasizes rapid reporting and visual content to cover global developments.^[35]^[36] Operated by a small team led by founder Stefan Tompson, a Polish-South African PR professional based in Poland, Visegrád 24 promotes an approach it describes as "open source journalism," involving quick curation of user-generated content, videos, and reports from around the world. The outlet frequently highlights topics related to Eastern Europe, the war in Ukraine, and international conflicts, often framing narratives in support of Western values and against perceived authoritarian influences. However, it has faced significant criticism for promoting unverified claims and exhibiting a right-wing bias, with reports accusing it of spreading misinformation through selective aggregation and sensationalized posts.^[37]^[38]^[39] Key activities include producing original video content such as street interviews and on-the-ground reporting; for instance, in 2025, Tompson and the team traveled to Taiwan to conduct interviews and document local perspectives on regional tensions. Visegrád 24 maintains a presence on Instagram and Facebook, amassing over 246,000 followers across these platforms by late 2025, where it shares similar curated content. Outlets like Visegrad Insight have specifically accused it of misinformation in 2023 analyses, pointing to instances of repackaged material with a conservative spin that misleads audiences on sensitive geopolitical issues.^[35]^[40]^[39] Although named after the Visegrád Group—a regional alliance of Central European countries—Visegrád 24 operates independently and is not officially affiliated with the organization. It positions itself as a counter to "media warfare" targeting Western democratic principles, often emphasizing threats from migration, extremism, and foreign disinformation campaigns in its coverage.^[36]^[38]
