Hyplane: a single-stage suborbital aerospaceplane

Area of Science:

• Aerospace Engineering
• Hypersonic Flight Technology
• Sustainable Aviation

Background:

• The HYPLANE project investigates a bizjet-sized aerospaceplane for rapid suborbital and stratospheric flights.
• The concept leverages existing high Technology Readiness Level (TRL) technologies for accelerated market entry.
• It aims to bridge the gap between commercial aviation and spaceflight for tourism and research.

Purpose of the Study:

• To report the current status and advancements of the HYPLANE project.
• To outline the potential applications of the HYPLANE aerospaceplane, including space tourism and high-speed point-to-point transportation.
• To highlight the technological feasibility and market potential of the HYPLANE concept.

Main Methods:

• Conceptual design and feasibility study of a horizontal take-off and landing (HTOL) aerospaceplane.
• Integration of advanced aeronautical and space technologies.
• Analysis of flight dynamics, performance, and operational capabilities, including runway requirements and environmental impact.

Main Results:

• The HYPLANE concept is designed for Mach 4.5 cruise speeds, reaching stratospheric altitudes of 30 km.
• It ensures flight safety and passenger comfort comparable to current commercial aviation standards, with manageable accelerations and load factors.
• The aircraft's design allows operation from over 5000 global airports with short runways, minimizing noise and sonic boom impact.

Conclusions:

• HYPLANE presents a viable concept for fast, safe, and accessible stratospheric and suborbital transportation.
• The project's reliance on high-TRL technologies supports a relatively short time-to-market.
• The aerospaceplane's operational flexibility and reduced environmental impact enhance its commercial and social acceptability.
