The SENECA consortium is carefully composed in order to collectively fulfil the projects objectives of local and global environmental impact assessment and technologies that minimize the impact of a supersonic fleet most successfully. The consortium participants cover all the necessary competences and complementarities of the project.

The limited data available for the certification process of supersonic airplanes is addressed in SENECA by
assessing four different aircraft platforms of different size and cruise Mach number. The development of the airplanes, the engines and the assessment of the local and global environmental impact will be done parallel by industrial (RRD and MTU), academic participants (DLR, ONERA, NLR, CIRA, CU, UoS, MMU and NAU) and SME (AEDS). The work split between industrial project participants with a considerable experience and well validated procedures for the certification of aircrafts on one hand, and academic participants able to support the investigation of SST cutting-edge technologies on the other hand, is perfectly complementary to serve the objective of the call. It will allow a benchmarking of the results, assumptions and methods applied and finally increase the reliability of the generated data. Several project partners (DLR, NAU, MMU and RRD) are already participating in the CAEP working groups and will ensures a frequent exchange and constant adaptation of the project work with regard to the ongoing certification discussions.

    The Cranfield team will involve field experts from the School of Aerospace, Transport and Manufacturing (SATM). Specifically, two world-renowned Centres within SATM will participate in the consortium, namely the Centre for Propulsion Engineering and the Centre for Aeronautics:
    • Centre for Propulsion Engineering: The capabilities within the ‘Centre for Propulsion Engineering’, headed by Prof. Pericles Pilidis, encompass a comprehensive portfolio of activities including analytical research, large-scale laboratories, and reputed educational programs (such as the MSc in Thermal Power) covering gas turbine technology, turbomachinery and icing research, and engine performance and diagnostics. The Centre has a strong track record in power plant modelling and performance simulation. Research activities in the past 50 years cover virtually every aspect of the field, such as steady-state and transient performance simulation, diagnostics, novel cycles, engine control, advanced simulation methods, power plant integration, engine design for subsonic and supersonic flight, etc. The Centre has established an international reputation for its advanced postgraduate education, extensive research activity, applied continuing professional development and participation in many EU projects. This is strengthened by close links developed with international propulsion industry partners. An example of this is the ‘Rolls-Royce University Technology Centre (UTC) for Aero Systems Design, Integration & Performance’, headed by Prof. Vassilios Pachidis who will act as the Cranfield Point of Contact in SENECA. The Rolls-Royce UTC was founded in Cranfield in 1998. The UTC’s core competence is its ability to undertake detailed studies involving highly integrated, aero-thermal, multi-disciplinary models to improve understanding of power plant and sub-system design, integration, and performance in the context of the product’s life cycle and mission. Research within the UTC has traditionally focused on the aero- thermodynamic performance analysis and optimisation of prime movers. However, for a number of years now, the original kernel of the UTC has been gradually expanding to include many other aspects of the wideroperation of the gas turbine and its various sub-systems (e.g. structural integrity, engine certification, operability, environmental impact including contrails, optimisation, novel cycles, alternative fuels, cooled cooling air, turbine tip clearance control, advanced variable geometry architectures etc.). More recently, focus has been placed on the integration of the power plant with the airframe and its performance analysis from a systems perspective. A lot of the pioneering work conducted within the UTC lies in the investigation of new advanced engine cycles for subsonic and supersonic aero applications as well as the optimisation of today’s technology through interdisciplinary performance modelling and a better understanding of the behaviour of various sub-systems throughout the operating envelope
    • Centre for Aeronautics: The Centre is internationally recognised as the first choice for research and education in Aerospace Design and Analysis, Advanced Engineering Methods, and Systems Engineering. The Centre has developed and maintained a strong track record in aircraft design, MDO, aerodynamics, aeroelasticity, flight control and handling qualities through its continued research. The Centre’s Aircraft Design Group is very multidisciplinary in nature and is often described as Cranfield’s own ‘Skunk works’. Its ability to offer expertise in specialist areas and to integrate these technologies to create innovative solutions for the needs of industry and society, is its greatest strength. The teaching activities within the centre include the renowned MSc in Aerospace Vehicle Design, which draws students from all around the world and is very highly regarded within the aerospace industry. Research activities cover a wide range of aerospace systems design and applications, including conceptual design.

    Role in Project

    Noise is one of the limiting factors for air traffic growth in Europe today. Despite the proven rising demand for air travel, the expansion of airports is, amongst others, limited by the expected increase in noise pollution, in particular for supersonic aircrafts. Supersonic aircrafts will be an enabler for fast global transportation. However, the noise from such an aircraft is expected to be substantially higher than from a conventional turbofan engine. It is therefore necessary to study the different noise sources of engines for supersonics aircrafts in order to further improve the knowledge about the dominant noise mechanisms and to increase the confidence in noise prediction tools. In the end, this will allow an integrated engine design with consideration of the noise foot print from the start of the engine design on. An essential part in the noise prediction is to study sensitivities towards different ambient and boundary conditions: Fan noise from an engine on a quiet day will differ strongly from the same engine being operated on a harsh and windy day. Hence MTU will improve their fan noise prediction tools and apply these tools to study fan noise from an engine for a supersonic aircraft under different ambient conditions. The findings will then be used to investigate the impact of different ambient conditions on the noise certification values. Furthermore, MTU will investigate the effect of noise shielding for different engine positions. Based on this study, a trade-off between an engine position optimized for SFC compared with a position optimized for noise is developed. As work package leader, MTU will oversee all activities in the work package dedicated to noise. MTU Aero Engines is member of the national German aerospace association BDLI co-chairing the board of the association. Furthermore, MTU is national representative in the European Aerospace and security association ASD.
