  • A device for measuring heat flux on a rocket skin surface
    Publikacja

    A novel method for measuring heat flux on a surface is presented. It is an extensive upgrade of currently known heat flux sensors used mostly in civil engineering. As the thermal environment of launchers, especially sounding rocket can have an enormous negative effect on payload, careful considerations have to be taken in the process of preparing insulation. Usually, thermal data provided by the launch vehicle manufacturer is limited...

  • Combined environmental testing device for picosatellites
    Publikacja

    As access to space conditions becomes more available, both technically and economically, scientists’ interest in launching finer and more sophisticated experiments grows. To be qualified for launch, such experiments need to be carefully tested prior to the event. The tests should represent actual launch conditions as closely and in a detailed manner. Typical tests for payload include: vibration tests, thermal and vacuum tests,...

  • Creating Polish space language dictionary - lessons learned
    Publikacja

    Polish space industry suffers from lack of space vocabulary. Since joining European Space Agency in 2012, the sector has expanded rapidly now employing over 1000 specialists focusing mainly on space sustainability, space debris detection and tracking, robotics and propulsion systems. The Polish Space Agency together with The Polish Committee for Standardization have committed to creating the first lexicon of space language, along...

  • Investigating lubricants behaviour in microgravity for vibration damping purposes

    Vibration is one of the harshest environments an object is exposed to during and after launch into space on a launch vehicle. Such vibrations should be damped to avoid destruction of the spacecraft or its elements. Currently, active and material damping is used. A possibility of using lubrication as the damping factor is suggested by some research. MoS2 is a typical solid lubricant used in space applications. Its properties vary...

  • Sounding rocket vibration mechanical filter and amplifier

    Measuring accelerations and vibrations of a sounding rocket provides both information for engineers on the launcher vehicle performance as well as environment description for future payload designers. Typically, information on the level of vibration and eigenfrequencies are required to properly design a payload. This paper presents a design of a novel mechanical filter and amplifier for mechanical vibrations. Its key feature is...

  • „Gdański eksperyment” studentów PG poleci rakietą z Europejską Agencją Kosmiczną
    Publikacja

    - Pismo PG - Rok 2018

    Pięcioosobowy zespół studentów Politechniki Gdańskiej, który przyjął nazwę HEDGEHOG (High quality Experiment Dedicated to microGravity Exploration, Heat flow and Oscillation measurement from Gdansk), zakwalifikował się do programu REXUS/BEXUS Student Experiment Programme koordynowanego przez Europejską Agencję Kosmiczną (ESA). W lutym 2018 roku studenci polecą do kosmodromu Esrange nieopodal Kiruny w północnej Szwecji, by poszerzyć...

  • Governmental supported space internship programmes in new ESA member states - Polish perspective
    Publikacja

    - Rok 2018

    Over last 10 years ve new countries - Czech Republic, Romania, Poland, Hungary and Estonia - have joined the European Space Agency. These countries are currently experiencing a considerable increase of space activities aiming to take part in the European and Global space market. New companies, start-ups and consortiums have been created alongside oces of foreign entities have opened their premises in these countries. All of them...

  • High-quality Experiment Dedicated to microGravity Exploration, Heat Flow and Oscillation Measurement from Gdańsk

    In this paper we propose HEDGEHOG (High-quality Experiment Dedicated to microGravity Exploration, Heat flow and Oscillation measurement from Gdańsk) REXUS experiment to investigate vibrational and heat flow phenomena during the whole (ascent, microgravity phase, descent and recovery) flight of a sounding rocket. First, a proposed system of cantilever beams is discussed to study dynamic behaviour of dummy payload. Dimensioning has...

  • Introducing concurrent engineering to space and satellite technology undergraduate course
    Publikacja

    - Rok 2018

    In recent decade concurrent engineering has become a de facto leading methodology of work in space, aeronautics and sometimes even automotive industry. It has been used in designing ESA space missions for 20 years now, with rst Concurrent Design Facility (CDF) built in ESTEC in 1998. Still, it has not become a universal standard in engineering, and universities are specically reluctant to adopt it into their curricula. As a result,...

  • Wstęp do badań wpływu ciśnienia na drgania mechaniczne na potrzeby modelowania ładunków rakiet kosmicznych
    Publikacja

    Środowisko dynamiczne rakiety kosmicznej jest wyjątkowo trudne dla ładunków wynoszonych w przestrzeń kosmiczną. W świetle zwiększonego zapotrzebowania na wynoszenie delikatnych eksperymentów, coraz dokładniej badane są drgania w trakcie lotu takiej rakiety. Aby przeanalizować wpływ drgań rakiety na ładunek, należy utworzyć model fizyczny, a następnie matematyczny odzwierciedlający zjawiska tam zachodzące. Jednym z ważniejszych...

  • Metody testowania wibracyjnego elementów wynoszonych w przestrzeń kosmiczną
    Publikacja

    - Rok 2017

    W trakcie wynoszenia ładunku w rakiecie, poddawany jest on wielu obciążeniom, których efektem są m.in. jego drgania. Zanim element zostanie dopuszczony do wylotu, przeprowadzona musi zostać analiza obliczeniowa oraz ładunek musi zostać poddany testom zgodnie z normami. W pracy przedstawiono wstępne obliczenia metodą elementów skończonych, które wykazują, że obciążenia podczas testów są większe niż podczas lotu, co może otwierać...
