Long-term Development Paths in Passenger Aviation

DEPA 2070

DEPA 2070

Overview of Future of Passenger Aviation

The "DEvelopment Pathways for Aviation up to 2070" (DEPA 2070) project, conducted by the German Aerospace Centre (DLR), examines the future development of passenger aviation up to the year 2070. The focus is on the analysis of trends, the development of aviation scenarios, and the evaluation of innovative technologies and their impacts on the environment, economy, and society. DEPA 2070 builds on the insights gained from the DEPA 2050 project and offers concrete perspectives for the sustainable transformation of aviation.

Project duration: 1 January 2022 to 31 December 2024

Solutions for the Future of Aviation

With DEPA 2070, the German Aerospace Centre (DLR) is developing comprehensive scenarios for the future of passenger aviation to identify new technological solutions that reconcile ecological and economic objectives. The project analyses long-term trends in areas such as propulsion technology, alternative fuels, and maintenance. External factors such as population growth, energy prices, and geopolitical developments are also considered.

Motivation and Background

The DEPA 2070 project supports the strategic orientation of the aviation industry and helps to design realistic development pathways for passenger aviation. In light of current challenges such as climate change and increasing mobility needs, the project aims to find solutions that make aviation climate-compatible and future-proof.

Research Topics

  • Creation of realistic development scenarios: Describing and quantifying detailed, vehicle-specific development and aviation scenarios up to 2070, based on trends in technology, energy, and infrastructure, as well as societal and political changes.
  • Technology and sustainability analysis: Analysing the ecological, economic, and social effects of long-term aviation development. This includes evaluating the aforementioned scenarios and exploring the technological and economic potential of innovative aviation technologies.
  • Evaluation of future aircraft concepts: Identifying, evaluating, and developing technology pathways for forward-looking aircraft concepts and new market segments, considering both ecological and economic sustainability.

Project Goals
