Predicting specific helicopter designs and technologies beyond 2024 is challenging due to the rapidly evolving nature of aerospace engineering and technological advancements. However, we can speculate on potential trends and innovations that may shape the future of helicopters:

Electric and Hybrid-Electric Propulsion: Building on current trends towards sustainability and emissions reduction, future helicopters are likely to see increased adoption of electric and hybrid-electric propulsion systems. These systems offer lower operating costs, reduced environmental impact, and potentially quieter operation compared to traditional combustion engines.
Advanced Materials and Manufacturing Techniques: Continued advancements in materials science and manufacturing technologies could lead to helicopters constructed from lightweight yet incredibly strong materials such as carbon composites or advanced alloys. These materials would improve performance, fuel efficiency, and durability while potentially reducing maintenance requirements.
Autonomous and Semi-Autonomous Flight: The integration of autonomous and semi-autonomous flight systems will likely continue to evolve, enabling helicopters to operate more safely and efficiently in a wider range of conditions. Enhanced sensors, artificial intelligence, and advanced navigation systems will contribute to improved situational awareness and autonomous decision-making capabilities.
Vertiports and Urban Air Mobility (UAM): As urbanization and congestion in cities continue to increase, there may be a greater emphasis on developing infrastructure for Urban Air Mobility (UAM). Future helicopters could be designed to operate from vertiports or designated landing pads within urban areas, offering a convenient and efficient mode of transportation for short-distance travel.
Advanced Cockpit and Avionics Systems: Cockpit designs and avionics systems are likely to undergo significant advancements, incorporating touch-screen displays, augmented reality overlays, and intuitive interfaces to enhance pilot situational awareness and reduce workload.
Noise Reduction Technologies: Efforts to mitigate helicopter noise pollution will likely intensify, with the development of innovative noise reduction technologies such as active noise cancellation systems, optimized rotor designs, and sound-absorbing materials.
Unmanned Aerial Vehicles (UAVs) Integration: The integration of unmanned aerial vehicles (UAVs) into helicopter operations for tasks such as cargo delivery, surveillance, and search and rescue missions may become more prevalent. Future helicopters may be designed to operate autonomously or in collaboration with UAVs to perform a wide range of missions more efficiently.
These are just a few speculative avenues for the future of helicopters beyond 2024, and actual developments will depend on a variety of factors including technological breakthroughs, regulatory considerations, and market demands.
