The study uses novel analytical methods to quantify the mission design space including the required sail performance to achieve a given solar polar observation angle within a given timeframe and thus to derive mass allocations for the remaining spacecraft sub-systems, that is excluding the solar sail sub-system. A parametric, bottom-up, system mass budget analysis is then used to establish the required sail technology to deliver a range of science payloads, and to establish where such payloads can be delivered to within a given timeframe. It is found that a solar polar mission requires a solar sail of side-length 100-125 m to deliver a 'sufficient value' minimum science payload, and that a 2.5 μm sail film substrate is typically required, however the design is much less sensitive to the boom specific mass.}, language = {en} } @inproceedings{FunkeHajAyedKustereretal.2014, author = {Funke, Harald and Haj Ayed, A. and Kusterer, K. and Keinz, Jan and Kazari, M. and Kitajima, J. and Horikawa, A. and Okada, K.}, title = {Numerical Study on Increased Energy Density for the DLN Micromix Hydrogen Combustion Principle}, series = {Combustion, Fuels and Emissions (ASME Turbo Expo 2014: Turbine Technical Conference and Exposition : D{\"u}sseldorf, Germany, June 16-20, 2014 ; Vol. 4A)}, booktitle = {Combustion, Fuels and Emissions (ASME Turbo Expo 2014: Turbine Technical Conference and Exposition : D{\"u}sseldorf, Germany, June 16-20, 2014 ; Vol. 4A)}, publisher = {ASME}, address = {New York, N.Y.}, isbn = {978-0-7918-4568-4}, pages = {V04AT04A057}, year = {2014}, language = {en} } @article{FunkeDickhoffKeinzetal.2014, author = {Funke, Harald and Dickhoff, J. and Keinz, Jan and Anis, H.
