Propósito de la prueba de vuelo
En la prueba del túnel de viento en tierra del motor de succión de aire, (1) la diferencia en la fuerza de la turbulencia del flujo de aire causada por la complicada trayectoria del flujo y (2) la mezcla de diferentes gases debido al calentamiento del flujo de aire causó calentamiento aerodinámico y características del motor entre el vuelo real Hay una diferencia (Figura 1). Por este motivo, JAXA está realizando una investigación destinada a construir una herramienta de análisis que corrija los resultados de las pruebas de túnel de viento en tierra y prediga las características de los motores de succión de aire en condiciones reales de vuelo.

Esta prueba de vuelo se realiza para adquirir datos de combustión, etc. en vuelo real y evaluar la herramienta de análisis.

Si podemos construir una herramienta de análisis, podemos reducir la cantidad de pruebas de vuelo requeridas para realizar un futuro proyectil equipado con un motor de succión de aire y reducir los costos de desarrollo. El propósito de esta prueba de vuelo es adquirir datos durante el vuelo real además de los resultados de la prueba en el túnel de viento y verificar la herramienta de análisis.

Leidos wins $334m contract for multi-role hypersonic platform
23 December 2022

Virginia-based manufacturer Leidos has won a US Air Force (USAF) contract worth up to $334 million to produce a multi-role hypersonic platform.
Known as Mayhem, the initiative seeks to deliver a “larger class air-breathing hypersonic system capable of executing multiple missions”, according to the contract award, which was announced by the Department of Defense on 16 December.

“The Mayhem system will use a scramjet engine to generate thrust, propelling the vehicle across long distances at speeds greater than Mach 5,” Leidos says. “Leidos is tasked with designing and developing a large-class version that surpasses current air-breathing systems in range and payload capacity using digital engineering to ensure the design efforts help future development and transition.”

Missions for the Mayhem system could include intelligence, surveillance and reconnaissance and weapons delivery. A key element of the design, per contract requirements, will be a standardised payload interface, allowing the integration of multiple sensor packages or weapons.

The Pentagon is requiring such standardisation, which its calls Modular Open System Architecture (MOSA), in most of its new development programmes. Acquisition officials say the practice will cut down on the life cycle cost of defence programmes, while allowing the faster and cheaper integration of new technologies.

“To deliver the next generation of air-breathing hypersonic system, we’ll leverage our years of investment, knowledge and success in the hypersonic field,” says Steve Cook, president of Leidos-subsidiary Dynetics.
Leidos acquired Dynetics, which describes itself as developing cost-effective engineering and scientific solutions for national security, space and other sectors, for $1.65 billion in cash in 2019. When Leidos announced the deal in 2019, it listed hypersonics as one of the “growth sectors” in which Dynetics had experience.

Leidos is a relative newcomer to the aerospace sector, compared to more established players such as Lockheed Martin, Raytheon and Northrop Grumman. The firm beat out five other competitors for the Mayhem contract.

The win is Leidos’ second major hypersonic contract with the US military. The firm also won a US Army programme to deliver a long-range hypersonic weapon.

The company will perform development work for Mayhem at the Air Force Research Laboratory at Wright-Patterson AFB. A working hypersonic vehicle is due to be delivered by 2028, per the contract award.

The Pentagon’s internal technology accelerator has awarded two contracts aimed at delivering a reusable hypersonic vehicle and launch system.

The Defense Innovation Unit (DIU) on 15 March issued its first hypersonic development contracts to two firms: Australia’s Hypersonix Launch Systems and California-based Fenix Space.

The goal of the new programme is to reduce the cost and increase the pace of hypersonic testing... “Testing is both costly, slow to iterate and test ranges are limited,” the DIU notes. “The resulting slow pace of hypersonic research and development has significantly impacted the DoD’s ability to mature hypersonic technology and retain a competitive advantage.”

The latest hypersonic research effort was launched by the DIU last September and attracted 63 bidders, according to the office. The technology incubator is seeking to produce “a suite of modern, low-cost, high-cadence, dual-use airborne testing platforms”.

Requirements for the contract include providing an airborne testing vehicle capable of maintaining speeds above Mach 5 with a manoeuvrable and non-ballistic flight profile. The vehicle must also boast at least a 3-minute flight duration with “near-constant flight conditions”, the DIU says.

Hypersonix will provide that flight vehicle in the form of the company’s Dart AE: a hydrogen-fuelled scramjet craft produced in partnership with autonomous aircraft developer Kratos.

El Ejército de Tierra estadounidense ha llevado a cabo el ejercicio Thunderbolt Strike, el primer entrenamiento con su primer sistema de armas hipersónico de largo alcance (Long-Range Hypersonic Weapon o LRHW). El LRHW pretende alcanzar velocidades de Mach 5 en un arma superficie-superficie de muy largo alcance, con el que atacar objetivos críticos rápidamente.

El objetivo es disponer de la primera batería de armas hipersónica completa en otoño.
