DINO PDR 3/17/2018 Introduction • Structures is to interface and house all components onto DINO PDR 3/17/2018 Introduction • Structures is to interface and house all components onto a common chasse. • Structures will protect components from the space and launch environment, including but not limited to vibration, impact and radiation hazards. • Structures is to interface to the ICU via Lightband as well as provide interface for the Tip mass. • Structures will provide casing and structural connection for all components (Electronics, batteries, solar arrays, ect. ) Colorado Space Grant Consortium

DINO PDR 3/17/2018 Subsystem Requirements Imposed on Structures • • • Entire Structure with DINO PDR 3/17/2018 Subsystem Requirements Imposed on Structures • • • Entire Structure with mechanisms will be less then 9. 19 Kg Fixed base Natural Frequency > 100 Hz at the Shuttle interface plane (SIP). Center of mass is to be no more then. 25 in from centerline and 12 in from the SIP. Structural Ground will be isolated from Electrical Ground Structure must be electrically continuous (less then 1 ohm resistance) Structure will be coated to ensure against electrical shorting The completed satellite must fit within ICU envelope Structures must provide enclosures (As necessitated) and structural support to all electrical components. Structures must provide mounting for surface mounted solar arrays, aerofins, FITS and antennas (As necessitated) Meet all Safety concerns applicable to shuttle flight Colorado Space Grant Consortium
