Team A-2: Amanda Crawford Christian Johnson Roberto Gonzalez Sage Pasternacki Garrett Wright
PROJECT DESCRIPTION Orbital ATK has commissioned this capstone team to design a low-shock payload separation system that they can be built in-house at a fraction of the cost compared to what is currently on the market by their competitors. (1) Work with Orbital ATK mechanical engineers to understand the needs and desires of the delivered project. (2) Survey commercially available separation systems. (3) Develop design concepts that meet all requirements. (4) Perform trade studies to down select to a single design. (5) Manufacture a prototype. (6) Provide Orbital ATK with PDR and CDR presentations. (7) Final product will include design, analysis and manufactured prototype. March 19, 2017 Sage Pasternacki Orbital ATK Team A
COMPANY BACKGROUND Orbital ATK is a global leader in aerospace and defense technologies and is comprised of two companies: Orbital Sciences Corporation and ATK [1]. Orbital ATK is comprised of three main operating groups. These groups include [1]: ▪ Flight Systems ▪ Defense Systems ▪ Space Systems They have three main launch vehicles [2]: ▪ Antares ▪ Pegasus ▪ Minotaur March 19, 2017 Amanda Crawford Orbital ATK Team A
CURRENT SYSTEMS The separation systems we have researched so far include: ▪ Mark 2 Motorized Lightband (PSC) [3] ▪ NanoRacks Separation System, NRSS (NanoRacks) [4] ▪ RUAG Marman Clamp Separation System [5] March 19, 2017 Christian Johnson Orbital ATK Team A
REQUIREMENTS Customer Engineering Low Shock 100% Success rate Low relative cost Tipoff angle of less than 1 degree per second upon separation In-house manufacturability Can be stored and functional for up to 90 days Compatible with existing payload system Be able to carry up to 5,000 lbf No debris with separation Variable separation force (4.8 ft-lbf to 18 ft-lbf) March 19, 2017 Garrett Wright Orbital ATK Team A
