Special Issue Information

Dear Colleagues,

We are pleased to announce a new edition of the open access Special Issue on the MDPI journal “Aerospace” dedicated to on-board systems design for aerospace vehicles. The aim of this Special Issue is to collect the most recent research advancements in the field of on-board systems design, belonging to both aeronautics and space vehicles, with focus on innovative concepts and technologies. In fact, systems engineering in the aerospace domain represents one of the most complex challenges of our time and we strongly believe that the dissemination of relevant results in this field is crucial to support and inspire the work of the scientific community. As Guest Editors of this Special Issue, we kindly invite you to submit full-research articles manuscripts addressing (but not being limited to) the following topics:

  • High-level design of on-board systems including functional architecture definition and concept of operation;
  • Model-Based Systems Engineering practices for aerospace systems design;
  • Aerospace systems modelling and simulation;
  • Heterogeneous simulation techniques for dynamic performance assessment of aerospace systems.
  • Digital twin concepts for aerospace systems analysis and design;
  • Reliability and safety assessment of on-board systems;

Current research efforts on commercial supersonic flight aim to overcome past challenges by designing a new generation of sustainable supersonic airplanes. Achieving this goal requires careful consideration of the propulsion system during the design process. This study proposes a mixed-flow turbofan engine model coupled with emission estimation routines to increase the reliability of the conceptual design of future supersonic aircraft. The model enables parametric analyses by analyzing variations in main engine design parameters (πc,πf, BPR) as function of the system and mission requirements, such as the Mach number, and suggesting applicability boundaries. The overall methodology was applied to a low-boom Mach 1.5 case study, allowing for both on-design and off-design analyses and generating a propulsive database to support preliminary mission simulations and chemical emission estimation. Finally, the accuracy and reliability of the engine model was validated against GSP 11 data for a generic mixed-flow turbofan engine. A modified version of the Fuel Flow Method, originally developed by Boeing, allows for emissions estimation throughout the mission for a supersonic engine using biofuels. The application of the methodology led to the definition of an engine with a πc  of 30 and BPR of 0.7 for the selected case study, which was successful in meeting the initial mission requirements.

Addressing real-time aircraft target detection in microsatellite-based visible light remote sensing video imaging requires considering the limitations of imaging payload resolution, complex ground backgrounds, and the relative positional changes between the platform and aircraft. These factors lead to multi-scale variations in aircraft targets, making high-precision real-time detection of small targets in complex backgrounds a significant challenge for detection algorithms. Hence, this paper introduces a real-time aircraft target detection algorithm for remote sensing imaging using an improved lightweight attention mechanism that relies on the You Only Look Once version 7 (YOLOv7) framework (SE-CBAM-YOLOv7). The proposed algorithm replaces the standard convolution (Conv) with a lightweight convolutional squeeze-and-excitation convolution (SEConv) to reduce the computational parameters and accelerate the detection process of small aircraft targets, thus enhancing real-time onboard processing capabilities. In addition, the SEConv-based spatial pyramid pooling and connected spatial pyramid convolution (SPPCSPC) module extracts image features. It improves detection accuracy while the feature fusion section integrates the convolutional block attention module (CBAM) hybrid attention network, forming the convolutional block attention module Concat (CBAMCAT) module. Furthermore, it optimizes small aircraft target features in channel and spatial dimensions, improving the model’s feature fusion capabilities. Experiments on public remote sensing datasets reveal that the proposed SE-CBAM-YOLOv7 improves detection accuracy by 0.5% and the mAP value by 1.7% compared to YOLOv7, significantly enhancing the detection capability for small-sized aircraft targets in satellite remote sensing imaging.
