• QB50 Deployment System Design
• QuadPack PDR results
• ICD Update
your vonlogo Karman here Institute 2 for Fluid Dynamics www.QB50.eu Objectives
• Deploy 50 CubeSats (40 x 2U 10 x 3U)
• Provide interface for Gossamer-1
• Allow flexible • choice of launch vehicle • deployment sequence • deployment direction
your vonlogo Karman here Institute 3 for Fluid Dynamics www.QB50.eu Cluster Concept
• Uses several QuadPacks • Will gain flight heritage after precursor campaign • Minimize risk of new technology • Very flexible with respect to launch vehicle, deployment direction and deployment sequence • Allows a scenario with several launches without re- development
your vonlogo Karman here Institute 4 for Fluid Dynamics www.QB50.eu Cyclone-4 Concept
• Cyclone-4 • All QB50 CubeSats fits • 2U flexible deployment angle • Gossamer check compatibility

your vonlogo Karman here Institute 7 for Fluid Dynamics www.QB50.eu Open Points
• Launch vehicle
• Available volume
• Obstacles in deployment direction
• Upper stage attitude control available for us to utilize
• Actual mechanical interface
your vonlogo Karman here Institute 8 for Fluid Dynamics www.QB50.eu Action Items
• Finish work on QuadPack
• As more information on launch vehicle, volume, attitude control and mechanical interface become available identify lower level requirements
• Check compatibility of Gossamer and the available volume on the proposed Cyclone-4
