Objectives

Tactical transport aircrafts are the workhorses of battlefields, fulfilling missions like airdrop delivery, parachutist drop, logistics, medical evacuation (MEDEVAC), air to air refuelling, special missions under harsh and adverse conditions, which are critical for the success of military operations. Operations in hostile environments demand e.g., built in electronic warfare self-protection systems and set requirements on the platform performance/build up in order to be suitable for the task, and furthermore to operate with limited ground infrastructure (e.g., unprepared runways).

Beyond their pure military role, tactical transport aircrafts are also key assets for a better civil defence/protection and EU-internal needs, with critical contribution to disaster relief, search-and-rescue and sanitary crises response.

Beside the A400M, which is on the high-performance side of the capacity, the initial conception of the majority of currently operating tactical aircraft (C130, C-295, C-27J …) is now 40 years old, and there is a need for a new medium tactical European aircraft, lighter than the A400M that could provide a complementary capacity for tactical transport.

Currently, some EU Member States are operating medium payload tactical military transport aircrafts within their fleet, which can be replaced with growing capabilities, able to cope with the envisaged operational challenges.

The Future Mid-size Tactical Cargo aircraft (FMTC) feasibility study proposal for EDF 2022 addresses this coming strategic gap within the European transport portfolio. FMTC proposes a cooperative analysis of the transport aircraft replacement needs on the 2030-2050 horizon and the identification of European development opportunities, among the EDF participating Member States and associated countries.

This topic is an opportunity for Europe to federate efforts by providing the EU defence community (nations and industry) with robust elements to decide what the 2035+ future of EU military tactical transport could be.

Scope:
Scope and types of activities

Scope

The scope must cover the feasibility study phase of the possible development of a future tactical transport aircraft.

Proposals must include at least the following activities:

Feasibility Study for one or two aircraft, depending on the convergence on the requirements by the participating Member States and associated countries;
Preliminary requirements review (PRR) accepted by the cooperating Member States and associated countries, which will confirm the technical, programmatic, industrial and market feasibility of the analysed solutions, giving participating States all necessary elements to select the aircraft configuration that could be carried forward through a development and industrialization phase.
...
Functional requirements

The proposition of a new aircraft development would be based on:

1. Intangible:

European Geo return: Development and involvement of European industries, acting as tractor for many European aerospace companies and small and medium-sized enterprises (SMEs);
Export opportunities: Custom made to fit EU partner's requirements, with :arrow: open architecture to address worldwide opportunities;
Based on operational scenarios & threat environment 2030+ (i.e., Multi Domain connectivity).

2. Tangible:

· Affordability, in terms of acquisition and lifecycle costs. Operating costs below similar available solutions in the market;
· Operations in demanding unprepared runways, hostile environments and tactical intra theatre operations;
· Flexibility for operating different kind of military missions and possibly reconfigurable for supporting civilian needs;
· Logistics capability: ability to carry tactical vehicles that do not fit in existing solutions;
· Multi-mission capability: ability to act as a multi-mission transport platform and be customized for specific roles;
· State of the art development, ensuring availability and reliability of the platform and avoiding obsolescence concerns;
· Sustainability along the entire product lifecycle: from the conception / production by means of digitalisation up to the product use with reduced environmental footprint due to e.g., advanced propulsion system, low weight and more efficient flight capabilities.

Expected Impact:

· Reinforce the European strategic autonomy in the military transport segment;
· Develop vital military capabilities in highly contested environments (e.g., tactical transport, airdrop, air assault) against technologically advanced adversaries;
· Develop EU MEDEVAC capabilities and EU disaster relief, and sanitary crisis response capabilities;
· Promote and protect the European technological and industrial ecosystem, based on a potential new aircraft development;
· Enhance cross-border collaboration (from large industrial groups to SMEs) through the opportunities offered by the several elements of the platform and its architecture.

Hay ciertos requerimientos que chocan. Por una parte parece, que escarmentados con el A400M, quieren algo más barato y sostenible. Pero después le piden capacidades mayores de supervivencia, con una propulsión más eficiente, electrónica a la última y una construcción más ligera. Otros puntos son algo difusos, como el que dice que tiene que ser capaz de transportar vehículos tácticos pero no se especifica tonelaje ni volumen. Hay cosas interesantes, como que piden precio por uno o dos prototipos para la década de los '30 y también arquitectura abierta. Otro punto interesante es que se ha de ser más polivalente que el A400M, contando incluso con una versión para misiones civiles (¿transporte de paquetería?).

De momento, han firmado Alemania, Francia y Suecia. Sin embargo, viendo cómo van las cosas en el FCAS, lo más probable es que no acabe en nada...

Las malas lenguas dicen desde hace años que este proyecto es "propiedad" de Manchin y es algo acordado con IG Metall.

Por otro lado opino lo que tu: state of the art, asequible y proyecto multinacional europeo en la misma frase es un oximoron.

El TsAGI ruso completa el tercer ciclo de investigación sobre el Slon, diseño pensado para sustituir al An-140: https://www.ainonline.com/aviation-news ... lcp-389487

...
As a result of the third iteration, TsAGI has introduced a number of corrections from the previous Slon layout. The most significant change involves an enlarged fuselage cross-section to accommodate bulkier cargo loads.

The aerodynamic fairing for wing-to-fuselage attachment points has become smaller. Designers also improved the shape of the engine pylons and nacelles to better house the PD-35.

A refined aerodynamic model for wind testing incorporates the changes. It features a wingspan of 5.9 feet and a length of about 6.56 feet. Engineers used complex 3D technologies on computer-aided manufacturing tools to make the parts for the model.

Despite the stated completion of the third research cycle, TsAGI intends to carry on with additional wind testing before year-end focused on typical cruise flight conditions. For that, the institute will use of its T-106 wind tube running at different modes, including variable air density. The scaled model will undergo testing with a few alternative versions of the winglets.

TsAGI characterizes the Slon as “optimized primarily for civil applications,” whereas the Ruslan has served both air forces and commercial airlines. “Thanks to the latest decision to enlarge the fuselage cross-section, we will be able to offer our customers a better solution to do with the transportation of larger-volume cargoes at distances they specified,” TsAGI representative Alexander Krutov said. “Besides, the wing with improved winglets will provide a higher lift to drag ratio.”

Area of Interest (AoI): Blended Wing Body (BWB)

The Department of Defense (DoD) is seeking a concept of design (CoD) of an advanced aircraft configuration that provides at least 30% more aerodynamic efficiency than the Boeing 767 and Airbus A330 families of commercial and military aircraft, enabling operational advantages such as increased range, loiter time, and offload capabilities. When integrated with projected 2030 engine technology, this advanced aircraft configuration is expected to provide at least 60 percent mission fuel burn reduction compared to current day technology.

In support of the 2018 National Defense Strategy (NDS) and the 2022 NDS Fact Sheet, the DoD is committed to improving our capability and readiness by accelerating operational energy technology advancements and innovation.?? The Department is presently the largest consumer of petroleum-based energy in the Federal Government, contributing to 77% of overall consumption. The majority of that is attributed to fuel for aircraft sorties supporting global operations. Decades of research and development indicate that advanced airframes such as blended wing body (BWB) aircraft present aerodynamic efficiencies that could both reduce fuel consumption and increase operational effectiveness, enabling longer-range sorties and reduced fuel logistics/supply chain risks.

Product/Technical Requirements

The digital CoD of a full-scale prototype must include:

· Digital engineering tools and processes to design, develop, test, verify, validate, and certify the system for possible follow-on prototype build, live-fly, and production.
· Program-specific engineering models in System Modeling Language (SysML) format that serve as the Authoritative Source of Truth (ASoT) for the entire design.
· A modular open system approach (MOSA) to allow for system integration and future upgrades.

(cruzo los dedos y espero que Atticus jamas lea esto)

Substituyes el rotor por el SDLF, metes toberas orientables 90º y tienes una configuracion muy similar al F-35B pero con dos motores.

Pero con rotor, si señor, si señor... :c5
