“…Aerodynamic center or centers of pressure location were influence by the pressure surrounding the surfaces. [34,35] Therefore, its location migrates further from its original position when flying outside ground effect zone. This phenomenon disturbed the pilot handling capability and may require special control system or specific type of 3 dimension airfoil to solve this problem.…”

This paper focuses on the development of Ground Effect Craft (GEC). The ultimate objective of this paper is to comprehensively outline all publicly disclosed and well-known GECs. The scope of this paper encompasses a review of the design challenges and architectures associated with GECs that have been prevalent for more than 60 years. It delves into research, development, and enhancements of existing GECs throughout their history. In conclusion, considering current technological advances, GECs present substantial opportunities and potential to evolve into a viable mode of transportation, effectively bridging the gap between aircraft and ships. The incentive to overcome the economic challenges associated with fabricating and operating GECs is worthwhile, encouraging exploration and development toward a commercially viable GEC.

“…WIG crafts experience complex longitudinal stability, where the lifting advantage depends on the height above ground, as previously mentioned; however, that lift advantage also varies with the angle of attack. As such, there are three distinct ground effect regions [24] that present some difficulty in maintaining that optimum advantage [19], especially in the presence of waves that vary in height [42]. The simulation of the longitudinal stability problem was advanced by [43,44], including some lateral stability.…”

This paper introduces the conceptual design of a submersible seaplane that merges the maturity of the wing-in-ground (WIG or ekranoplan) crafts and seaplanes with covert hybrid underwater insertion, travel, and recovery. WIG crafts have a higher lift-to-drag ratio and thus improved endurance, while hybrid crafts have recently become feasible due to advances in materials, electric propulsion, and multi-medium computational fluid dynamics. The reconnaissance design can insert, loiter, and extract from underwater, surfaces if necessary; it can fly in or out of ground effect, keep watch on the sea surface while recharging, and travel underwater. This design minimizes Doppler and infrared signatures to evade the surface wave, backscatter radar systems, and cube satellite arrays typical in contested maritime areas. Five critical enabling technologies are overviewed, showing how they enable a conceptual design. This project was conducted in collaboration with two industrial partners, namely Ron Allum and Thales Australia. The conceptual design has been socialised and confirmed at technical conferences from each core discipline and partly confirmed by a recent Chinese design and testing of a similar hybrid uncrewed aerial vehicle (HUAV). Recommendations are made for improving the conceptual design before proof-of-concept prototype testing. Given the seminal nature of HUAV design and research and some of the unique innovations proposed, the lessons learned from this iteration will likely be significant to other designers and researchers.

“…Instead, there are two predominant schools of thought exist where problems of stability may be sorted out by sound performance design or by automatic control system, or perhaps both. Researches on WIGE crafts have been inclined towards using automatic control system [12][13][14][15].…”

A wing-in-ground-effect (WIGE) crafts can be deployed to fly by utilizing the ground effect, which is a natural phenomenon known to improve the efficiency of airplanes during take-off and landing approaches. In contrast, WIGE craft is not commercially viable for public transport mainly due to the difficulties in controlling its longitudinal stability. As an attempt to support the development of WIGE crafts, this paper presents a case study in aerodynamics based on certain published reports, specifically to reveal the available research data that are considered of interest and can be used as a lesson for further study and analysis. The wind tunnel procedure and testing, as well as numerical investigation of a WIGE craft, are applied and the results are then analyzed. The discussions are oriented in the perspectives of aerodynamics. Based on the tests and calculation, parameters concerning the ground effect as the WIGE crafts approaching the ground surfaces may be identified and hence their values can be determined. Thus, the static longitudinal stability may then be established and optimized for control of the WIGE craft.
