CubeSat missions have been deployed to cislunar space and beyond, paving the way for the next significant advancement: a dedicated CubeSat mission to explore a planet near Earth. To contribute to this goal, the German Aerospace Center (DLR) has developed radiation-hardened small satellite technologies, including communications, power and onboard...

The current project investigated the feasibility of aerocapture at Jupiter, and the benefits in terms of payload mass fraction that could be achieved compared to traditional orbital insertion burns. A numerical simulation model has been set up, as well as an analytical formulation of the problem. The numerical verification of the analytical...

Laser communication provides numerous benefits over typical Radio Frequency communication, such as lower power, not occupying regulated frequency bands, possibilities for much higher data rates and resistance to jamming. Combined with satellite constellations, Laser Inter-satellite Links (LISL) can enable global connectivity. However, satellites...

The proposed method in this study pretends to improve the mission analysis procedure by generating a tool that allows to rapidly compute the main parameters and characteristics of a SEP transfer towards an arbitrary PHO, avoiding the application of complex numerical methods in the preliminary phases of the mission design process to improve its...

The environmental impact of aviation is a well-known issue scientists all around the world are desperate to tackle. The population that can afford air travel is growing and this demand is likely to double within the next 20 years. This increasing demand comes at a hefty price: the emissions of greenhouse gases cause climate change and local air...

Recognising the threat of near-Earth objects (NEOs), many ground-based surveys have been deployed worldwide. However, ~20% of these potential impactors are estimated to be approaching us from the day-side, and are thus very difficult to detect using ground surveys. Over the last decade, several space-based capabilities have emerged in an effort...

Space safety and hazards reduction techniques are each day becoming more important in the design and operation of space transportation vehicles. One way to mitigate risks is to use advanced guidance strategies to centralise mission planning and guidance-navigation and control. Successive convexification is a technique suitable for this purpose...

It is the aim of this research to assess the mission performance of a boxwing aircraft by developing a configurationagnostic, multifidelity optimal control toolbox for performance and mission analysis. The boxwing aircraft, sometimes named a PrandtlPlane (PrP), is an unconventional aircraft. An instance with redundant controls is designed within...

The potential environmental benefits of hybrid electric regional turboprop aircraft in terms of fuel consumption are investigated. Lithium–air batteries are used as energy source in combination with conventional fuel. A validated design and analysis framework is extended with sizing and analysis modules for hybrid electric propulsion system...

In recent years, space missions to asteroids have been a focus of research. This type of mission has introduced a new challenge in space mission analysis: target selection. Indeed, given the large number of small Solar System bodies and their various orbital and physical characteristics, selecting a specific target is a rather complex task. This...

Noback, R. (author)
A method is derived to generate consistent sets of design load conditions if aircraft design loads are determined using the Design Envelope criterion of the Power Spectral Density (P.S.D.)-method. The method is based on the use of the correlation coefficients between the various loads. Two sets of design load conditions have special properties...
