Dutruel, Benjamin (author)
The startup Rocket Factory Augsburg (RFA) is developing the RFA ONE orbital launch vehicle. A significant hurdle for its closed-loop guidance is the need to fully deplete the third stage for insertion during the first flight, which results in lengthy burn-arcs and complexity not managed properly by traditional guidance algorithms. Additionally,...

In pursuit of cost-effective and sustainable space access, Dawn Aerospace is pioneering innovative launch systems. Their focus lies on a semi-reusable, two-stage-to-orbit launch vehicle, designed for horizontal take-off and landing. While current launch vehicles rely solely on rocket propulsion, the potential of airbreathing engines on the first...

RLV development can be considered as the modern step towards mission design due to financial and strategic decisions. In the past, reusability has been addressed however the level of maturity of the technology, both in terms of hardware and software was not yet reached. There are several aspects to developing a RLV, and these can be categorized...

The Mars Ascent Vehicle will bring samples back from the surface of Mars to its low orbit in 2031. Its preliminary design has been performed by NASA, defining it as a two-stage solid propellant rocket. However, a research gap exists in finding what the optimum solid rocket motors geometries are to bring the Martian samples to a target orbit...

A flight termination system (FTS) is one of the most important safety features on a launch vehicle, as it allows for the vehicle's flight to be terminated in a controlled way when predetermined safety criteria or boundaries are exceeded. Currently, T-Minus Engineering B.V. aims to develop a custom flight termination system for the Dart payload...

Single-Stage-To-Orbit (SSTO) launch vehicles are capable of reaching orbit while being potentially fully reusable. A technology capable of enabling SSTO access to space is the air-breathing engine, which has a high specific impulse and low thrust-over-weight (T/W) ratio compared to conventional rocket engines. This necessitates the use of a...

The small satellite market is rapidly growing and becomes more competitive by the day. In order to reduce launch costs, the concept of reusable launch vehicles wins popularity. Only few companies have managed to successfully recover and re-use their launch vehicle, of which SpaceX is the only one using a powered descent technique. This study...

Dawn Aerospace is developing a horizontal take-off and landing two stage to orbit partially-reusable launcher concept. The re-usable first stage spaceplane operates on a return to launch site trajectory and integrates into the existing airspace, flying as an UAV. For any re-entry vehicle the design needs to account for aerothermodynamic...

Aerosols, also known as particulate matter, are tiny particles or droplets suspended in the atmosphere which interact with solar radiation. These particles are partly responsible for cloud formation and are detected amongst others in (forest fire) smoke, dust, volcanic ash or sulfates. Aerosols have a large influence on the Earth’s climate as...

The last 20 years has brought with it a surge in efforts toward the Red Planet as the next frontier is human space exploration draws closer. Many concepts have been proposed for a sustained human settlement on Mars, with NASA’s ISRU-to-the-wall campaign identifying the need for a shuttle vehicle between theMartian surface and a station in an...

In previous research, the necessity of non-rigid body simulators was stated to be a requirement for long, slender bodies. However, it remains unclear for which vehicle design parameters non-rigid body effects become destabilising. A set of 2+N linearly independent equations of motions can be combined in a single matrix to determine the motion of...

With the increase of satellite constellations in orbit, the need for a Space Traffic Management (STM) is becoming undeniable. Within the scope of STM, an impartial and optimized collision avoidance advice based on the perspective of two manoeuvrable satellites could encourage more active collision avoidance and pre- vent on-orbit collisions....

The demand of small payload launch vehicles has been growing over the past years. Customers base their selection of launch vehicles on cost-effectiveness, flexibility, availability and reliability. A new launch vehicle, the Dawn Aerospace Mk-III, is proposed to be developed, while designed to take into account all these criteria.<br/><br/>For...

For decades the space domain has been used for military purposes. When enemy forces establish counter-space capabilities, this could become a weakness. Responsive Space is a concept that focuses on replenishing lost capabilities and/or granting additional capabilities from space assets quickly. The continuous miniaturization of technologies has...

In recent years the interest of the space community for electric propulsion has been rising thanks to the advantages that this technology offers. To ensure a correct integration on the spacecraft, it is important to be able to predict the behavior of the plasma plume generated by the thruster. Such plume could in fact damage spacecraft surfaces,...

During the design and analysis of a mission characterised by re-entry flight, consistent effort and resources are invested in the definition of the aerodynamic database of the re-entry vehicle. An aerodynamic database collects a set of dimensionless coefficients that describe the interaction of the vehicle's geometry and airflow, and an accurate...

Given the current technological limitations, launch missions are extremely costly: rockets are huge, being about 100 times more massive than the payload, and most of the times expendable. The specific cost required to place a spacecraft in LEO is between 10 and 25 k€/kg. Consequently, trajectory optimization plays a major role in the design of a...

An increase in the amount of launched satellites can be seen in the last decade. And it is expected that even more satellites will be launched in the upcoming years. Most of these small satellites are launched as piggy back together with a large spacecraft. The location and time of launch and orbit will therefore be determined by another mission...

The sea level determination in the Arctic brings challenges with it, due to its high seasonality, varying surface types and scarce in-situ observations. By developing a year round retracker system with an implementation of a bias removal strategy, the Arctic sea level determination is improved. Through the analysis of the seasonal performance of...
