About this role
Koninklijk Nederlands Lucht en Ruimtevaartcentrum logo Koninklijk Nederlands Lucht- en Ruimtevaartcentrum Homepage Internship: Hydrogen Leak Detection Requirements in a Hydrogen-Powered Aircraft - On-site - - Amsterdam , Noord-Holland , Netherlands - Aerospace Systems Background This internship focuses on the detection of hydrogen leakages and the measurement of hydrogen concentration, specifically in hydrogen-powered aircraft. In a future where more and more (test) aircraft will include hydrogen power trains, NLR aims to gain experience in hydrogen sensing applications for aerospace. Adequate detection of leaked hydrogen, which is highly flammable, will be an important way to comply with new safety and regulatory requirements that will apply to hydrogen aircraft. As an intern, you will define the requirements for hydrogen sensors for different types of aircraft, based on several safety specification documents. You will compare multiple hydrogen concentration sensors by different manufacturers with respect to compliance with these safety specifications, but also accuracy, response time, stability, specificity and ease of integration. This will include discussing with sensor manufacturers. Ultimately, NLR plans to build test setups for in-flight testing of hydrogen sensors in an actual hydrogen-powered aircraft. This internship will contribute to NLR's flagship PHYREX (Pipistrel Hydrogen Range Extender) project. Assignment - Define the requirements for hydrogen sensors inside or outside the fuselage for aircraft, based on CS-LSA, CC-23, CS-25, etc. - Propose means of compliance to these requirements. - Propose improvements to NLR hydrogen sensor ground test facilities. - Explore and evaluate the landscape of hydrogen concentration sensor manufacturers. - Report findings and provide recommendations. Result - An exhaustive requirements list for hydrogen sensors for different types of aircraft. - Trade-study and recommen...
