Submerged inlets have been widely used in advanced aircraft due to their excellent stealth characteristics, but they also suffer from poor aerodynamic performance. To improve the aerodynamic efficiency while maintaining stealth capabilities, this paper proposes a design scheme for a front auxiliary inlet with an inlet grille. The front auxiliary in...
A submerged inlet has good stealth characteristics and a low external drag, but it also has the disadvantage of low internal flow efficiency. In view of this, a new efficiency enhancement method based on the prepositive synergistic bulge of the inlet’s anterior lip is proposed. Taking the submerged inlet of an aircraft as the baseline configuration...
Accurate target recognition of unmanned aerial vehicles (UAVs) in the intelligent warfare mode relies on a highly standardized UAV knowledge base, and thus it is crucial to construct a knowledge graph suitable for UAV multi-source information fusion. However, due to the lack of domain knowledge and the cumbersome and inefficient construction techni...
A slot formed between the slat and the main wing of the 2D high-lift device is used to accelerate the convergence of the flow to the upper surface of the main wing to improve the flow field quality. In order to further enhance flow characteristics, this paper proposes a design method for multi-channel leading-edge slats based on grid flow channels....
Based on the bionic design of the humpback whale fin, a passive flow control method is proposed to obtain greater flapping lift by applying the wavy leading edge structure to the straight symmetrical flapping wing. The leading edge of the conventional flapping wing is replaced by the wavy shape represented by regular trigonometric function to form...

Submerged inlet has been widely used in UAVs and cruise missiles due to its good stealth characteristics, but it also brings the disadvantage of poor aerodynamic characteristics. Especially in large maneuvering flight, the flow field near the fuselage has a strong unsteady effect, and the total pressure recovery coefficient and distortion character...
The high-temperature and high-pressure shock waves generated after the explosion of a thermobaric bomb have a considerable impact on the aerodynamic characteristics of aircraft. Taking a typical thermoelastic model as the object, the explosion process was calculated by LS-DYNA software. The obtained pressure–time history curve data were written int...
As one of the important carriers, Notice to Air Men (NOTAM) provides key aeronautical security information during flight operation. However, a large number of NOTAM texts lack systematic utilization and organization. To improve the application of NOTAM texts, the Natural language processing can be used to classify and analyze NOTAM texts, and their...

... The effectiveness of using plasma actuators on an NACA 0015 airfoil at pre-stall AoA at a Reynolds number of 63000 is analyzed by Ogawa et al. [10]. An optimized design of a slat channel configuration, aiming to increase the lift of a given airfoil profile, is presented by Yu and Mi [11]. In fact, this final paper opens the door to the final chapter, which is Optimization Techniques (OT). ...
... In both cases, it was observed that appropriate three-dimensional blading resulted in an increase in static pressure and a reduction in the influence of secondary flows. A flapping bionic wavy leading edge wing is studied by Bai et al. [4], and they realized that it generated a higher lift than conventional airfoils. The passive flow-control application section is closed by the transient analysis undertaken on cruise missiles' submerged inlet by Zhang and Mi [5]. ...

The passive flow-control application section is closed by the transient analysis undertaken on cruise missiles' submerged inlet by Zhang and Mi [5].

... Des travaux ont déjà été menés sur les NOTAMs, par exemple dans un but de classification (Mi et al., 2022). Dans cet article, nous appliquons les dernières avancées en TAL au domaine aéronautique dans le but de réduire la charge de travail des pilotes. ...
... For aircraft maintenance faults, Wang et al. [8] proposed an ontology for aircraft faults in order to solve the problem that multi-source aviation maintenance data lead to syntactic and semantic conflicts, thus limiting the integration and sharing of aircraft fault information, which provides a unified and specific description of multi-source data and eliminates the semantic heterogeneity. For aviation intelligence and operational safety, Mi et al. [9] used natural language processing techniques and clustering algorithms to intelligently extract ontologies for navigational announcement information. ...
