AI Technical Summary

Technical Problem

Existing aircraft technologies, such as multirotor drones, fixed-wing drones, and airships, fail to effectively combine the advantages of maneuverability, payload capacity, flight range, and energy efficiency while minimizing drawbacks like helium dependency, large size, and wind sensitivity.

Method used

An aircraft with a self-stabilizing delta wing equipped with an airtight flexible envelope that generates lift through its aerodynamic profile, eliminating helium dependency and maintaining lift through air, allowing for compactness, maneuverability, and energy efficiency.

Benefits of technology

The aircraft achieves extended flight endurance, increased payload capacity, and improved stability in varying weather conditions, with reduced maintenance and infrastructure requirements, enabling long-range surveillance and logistical operations.

Abstract

The invention relates to an aircraft (2) comprising a wing (4) and means (6, 30) for propelling the aircraft (2); the wing (4) having a flexible, airtight envelope (18) designed to contain air; the flexible envelope (18) being configured such that, when it contains air in a nominal inflation state, the aerodynamic profile of the flexible envelope (18) alone generates the lift of the wing (4). The aircraft (2) may be a piloted aircraft of the airplane type or an unpiloted aircraft of the drone type. Abstract figure: Fig. 1
