Controlled deployment of CubeSat booms

The deployable boom for the SEAM project was uncontrollably deployed by the stored strain energy. One way of controlling the deployment speed without a motor is to use shape memory polymers, cf. shape memory alloys. By heating a part of the boom to a temperature above the glass transition temperature, the deployment for the heated part can be initiated.

EO4SmartCities

EO4SmartCities is a project within the Dragon 4 programme, a cooperation between ESA and the Chinese Ministry of Science and Technology during 2016-2020. The overall objective of this research is to develop EO-based urban information services to support smart cities and sustainable urbanization. 

The specific objectives are:

  • To develop novel methods for better characterization of spatiotemporal patterns of urbanization and assessment of urban capacity.
  • To explore advanced InSAR and Optical image processing technique for land surface classification and change detection.
  • To exemplify the smart city approach through Earth Observation in conjunction with GIS and urban models, in order to address two fundamental pillars of urban climate and environment:
    • Urban thermal environment, with emphasis to surface energy balance and the urban heat island, the presence and spatial distribution of thermal hot spots and energy efficiency at the district level.
    • Urban hydrology, with emphasis to urban flooding and subside.

KTH contributes with electronics and geodynamics. SNSB decided in October 2014 to finance MATS as the first project under the new national program for small satellites. The launch of the satellite is planned for 2019.

MERiT (MEthane in Rocket nozzle cooling channels - conjugate heat Transfer measurements)

A propulsion system using hydrocarbons, liquid or hybrid, is a grand challenge for today’s rocket and space propulsion systems. As a consequence of the good performance in specific thrust in combination with operating benefits such as low toxicity, availability, storage stability and low production cost, liquid biogas/natural gas (LNG) with a high content of methane is one of the most interesting future solutions as propellant for rocket engines with liquid fuel. A high heat flux thermal stability test rig for rocket nozzle cooling channels designed, built and operated at the Royal Institute of Technology (KTH). With the use of the test rig the industry and academia will be able develop necessary knowledge of the heat transfer characteristics and material influence at relevant operating conditions in order to maintain and gain new market shares in future rocket propulsion systems. In 2019 the test rig was installed with operating conditions of 200 bar and 1073K, with gas combustion.

X-Calibur and XL-Calibur

X(L)-Calibur is a balloon-borne hard X-ray polarimeter which uses a different instrument approach compared to PoGO+. A ~10 m long optical bench houses X-ray optics and a scattering polarimeter at the focal point. The optical bench is pointed with arcsecond accuracy. The XL-Calibur mission is a continuation of the X-Calibur mission which has conducted several test flights, culminating in observations of the accreting X-ray pulsar GX 301-2 during a flight on Antarctica in December 2018 which KTH participated in. XL-Calibur is a second-generation instrument which achieves approximately six times better sensitivity than X-Calibur. XL-Calibur will study a sample of archetypical X-ray sources (15-80 keV), including but not limited to, stellar mass black holes in X-ray binaries such as Cyg X-1 and GX 339-4, accretion and rotation powered neutron stars such as Her X-1, Vela X-1, GX 301-2, and the Crab, as well as a sample of flaring binaries.
