Special Issue "Propulsion/Airframe Integration"
A special issue of Aerospace (ISSN 2226-4310).
Deadline for manuscript submissions: closed (10 December 2017).
Advanced aircraft concepts are increasingly reliant on closer coupling of propulsion systems with airframe aerodynamics, or propulsion/airframe integration (PAI), for optimal performance. For instance, several advanced concepts employ fuselage boundary layer ingestion by turbofan engines to achieve a reduction in mission fuel burn. These benefits occur at the system level, and oftentimes traditional measures of sub-system efficiency, such as thrust-to-weight ratio, lift-to-drag ratio, and propulsion efficiency, are obscured by the integration since sub-system and system characteristics are inseparable. While advanced multidisciplinary analyses have led to exciting new possibilities thought to leverage the benefits of PAI, several research challenges face the community before these benefits may be fully realized.
Advances in PAI include creative placement and distribution of propulsion, but rely on tolerance of propulsion devices to the highly non-uniform inlet flows that often result. The aerodynamics and design of inlets and exhausts for embedded turbomachinery requires additional care to understand and minimize losses and distortions. Even with advanced inlet designs, it is likely that modification of the turbomachinery is needed for optimal performance and stability of the fan rotor in the presence of distortions. Finally, while integration can be used to shield propulsion noise sources, the precise role of shielding and the aeroacoustic response of fans and exhausts to distorted flows remain topics of research interest.
In this Special Issue, manuscripts are sought that report new research on:
- optimized airframe concepts with highly integrated propulsion systems.
- systems performance analyses for integrated propulsion systems.
- turbomachinery design, aerodynamic response, and aeromechanics for non-uniform inlet flow.
- aerodynamics of integrated inlets and exhausts.
- aeroacoustics of integrated propulsion systems.

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Aerospace is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1400 CHF (Swiss Francs).
