QB50 is a mission establishing an international network of 50 nano-satellites for multi-point, in-situ measurements in the lower thermosphere and re-entry research. As part of the QB50 mission, the Delft University of Technology intends to contribute two nano-satellites both being equipped with a highly miniaturized propulsion system in addition...

The number of micro and nano satellite projects is expanding. Main focus is on providing these small satellites with the same capabilities as today's larger satellites. In the field of propulsion, efforts are on miniaturization of the on-board propulsion system. This though presents major challenges to the designers. TNO Defence, Security and...

This paper attempts to answer the question whether it “pays” to apply Systems Engineering methods, tools and techniques within a space project. To this purpose a possible correlation has been investigated between the Systems Engineering effort applied within a number of space projects and the project result in terms of technical quality, cost...

The work focusses on the use of multidisciplinary optimization to design a cost optimized airborne nanosatellite launch vehicle capable of bringing a 10 kg payload into low earth orbit (LEO). Piggyback or shared launch options currently available for nanosatellites are relatively low cost (~45,000 €/kg) but have as serious disadvantage a limited...

At the Delft University of Technology the use of solar radiation to heat a propellant to a high temperature is investigated as an alternative to resistance heating. The latter only allows for a solar power to heat conversion efficiency of about 25%, depending on the solar cells, whereas for solar heating 80% seems feasible. This paper addresses...

A satellite design tool has been developed offering systems engineers a fast way to analyze the feasibility of a particular design concept. The tool differs from available tools on the market in that it is specifically targeted at small satellites in the mass range of 1-50 kg, and with a limited development time. The tool is developed in Excel,...

The development of highly integrated and compact micro-satellites and the need for a higher precision of positioning and attitude control in space missions has stimulated the development of micro-propulsion systems. At TU-Delft, investigations are focusing on non-chemical, thermal propulsion. TU-Delft is also collaborating with TNO and UTwente...

Erosion of the acceleration channel is the main lifetime limiting factor for Hall Effect Thrusters (HETs). Impacting ions damage the wall insulation that protects the magnetic circuitry from the plasma. To improve HET technology, it is necessary to simulate plasma behavior inside the channel, and associated erosion rates. This work presents a 2...

Methane is a promising propellant for liquid rocket engines. As a regenerative coolant, it would be close to its critical point, complicating cooling analysis. This study encompasses the development and validation of a new, open-source computational fluid dynamics (CFD) method for analysis of methane cooling channels. Validation with...

This paper presents the development work of the 10 kN hybrid rocket motor DHX-200 Aurora. The DHX-200 Aurora was developed by Delft Aerospace Rocket Engineering (DARE) to power the Stratos II and Stratos II+ sounding rocket, with the later one being launched in October 2015. Stratos II and Stratos II+ are the flagship projects of DARE, a student...

This paper describes the current developments regarding cryogenic rocket engine technology at Delft Aerospace Rocket Engineering (DARE). DARE is a student society based at Delft University of Technology with the goal of being the first student group in the world to launch a rocket into space. After the launch of the hybrid engine powered Stratos...

In the last decade, CubeSat development has shown the potential to allow for low-risk, low-cost space missions. To further improve the capabilities of CubeSats in large scale missions, a novel micro-propulsion system is being developed at Delft University of Technology. The system is based on a Vaporizing Liquid Microthruster (VLM), which is...

Incorporating propulsion in small satellites is becoming a growing trend, due to its potential for enabling new and ambitious mission objectives. One of these objectives is formation flying, that will be pursued by TU Delft for the DelFFi mission as part of the larger QB50 project. For DelFFi, two identical spacecraft will use propulsion to...

This paper presents a dynamic system approach for the modeling of fluid flow in microchannels to be used in thrust control applications. A micro-resistojet fabricated using MEMS (Microelectromechanical Systems) technology has been selected for the analysis. The device operates by vaporizing a liquid propellant, in this case water, and expelling...

Scanning transmission electron microscopy (STEM) imaging is applied to analyze the electromigration-induced thickness variations of thin polycrystalline films, It is shown that a high angle annular dark field (HAADF) detector is required to minimize the effect of diffraction contact. A further reduction of the diffraction contrast can be...
