The Sounding Rocketry Team consists of up to 32 dedicated students ranging from freshman to graduate students. SRT has created an organizational structure to manage its large and diverse set of knowledge and skills and to allow for individuals to develop themselves as well as advance the team. The structure has evolved over the years to account for areas in the design and testing process of rocket systems that past teams identified as points of improvement.
This is the SRT-5 organizational structure:
This is the SRT-5 organizational structure:
The Business sub-team consists of a manager and 3 general members, who will be tasked with securing the financial future of the team, keeping a detailed accounting record, and marketing the achievements, goals, and ideas to individuals inside and outside of the organization. SRT functions much like a start-up or research company. Selected members must demonstrate a strong entrepreneurial mindset and personal drive. This team is responsible for communication with sponsors, donors, faculty, and other university teams. The business team will also be responsible for funding and resource procurement, meaning daily responsibilities of maintaining a budget and allowing acquisition of parts for the team. Members will follow other sub-teams closely, documenting their technical work and relaying it to the public. Skills in photography, graphic design, accounting, and marketing are desired for this team. This sub-team performs critical operations that help fund and promote the Sounding Rocketry Team.
Testing & Operations
The Testing & Operations sub-team consists of a manager and 4 general members whose role is to characterize the rocket’s critical sub-systems through rigorous testing and analysis; this includes the hybrid engine assembly, the oxidizer control system, and the ground communication network. Additionally, the sub-team will have the responsibility of maintaining and improving testing infrastructure such as the static test cell and the vertical launch tower. Sub-team members will be expected to be become proficient in data acquisition, signal processing, and systems engineering concepts. A respect for procedural testing and a large time commitment will expected from all sub-team members.
The Propulsion team consists of a manager and 5 members who are tasked with developing, manufacturing, and characterizing robust and efficient hybrid propulsion systems for use in sounding rockets. Emphasis will be placed on research into the mechanics of a hybrid engine and its subsystems in order to optimize engine characteristics (thrust, burn time, mass flow rates, regression, etc.) and accurately predict performance through computational models. Members must be familiar with all components of a hybrid propulsion system (oxidizer tank, plumbing assembly, injector plate, combustion chamber, nozzle) and understand how these parts interact with one another. A background in chemistry, thermodynamics, and high speed aerodynamics is necessary, and experience with MATLAB, SolidWorks, and CFD is preferred. Additionally, prior machining experience is beneficial. Individuals will be expected to contribute a significant amount of time to research, fabrication, and testing while learning new concepts and skills quickly regardless of prior exposure.
The Structures sub-team consists of a manager and 4 general members whose role is to design, analyze, fabricate, and test all structural components of the team’s sounding rocket and launch infrastructure. This includes: fabrication of the rockets components (body tubes, nose cone, fins and bulkheads), materials testing/analysis, and design of major improvements to the launch trailer and launch tower. Members will be responsible for making and updating relevant 3D CAD/Solidworks models. Members will work with a variety of materials such as: composites, metals, and plastics to manufacture rocket components and launch equipment. Members will also perform experimental materials testing to characterize in-house composite mixtures, optimize manufacturability and provide structural integrity of all constructed rocket components. Mechanical design, structural analysis, and hands on experience with power tools/ machining is desired but not required.
Electronics and Payload
The Electronics and Payload team consists of a team manager and 3 general members who will oversee modifications and improvements to the rocket’s avionics, power, and communication systems via hardware and software design. The sub-team's goal is to produce robust, flexible systems capable of flight data acquisition, hybrid engine control, and parachute deployment through microcontrollers, sensors, and flight computers. Additionally, the sub-team will design, build, and test a functioning payload with the intentions of competing in the SDL Payload Challenge at the 2018 IREC. Restricted by rocket limitations and 8.8-pound weight limit, the team will have full liberty of overseeing the construction of a payload of scientific merit. The team’s work will require some basic programming experience (C, C++, Python, LabVIEW, etc.) and some familiarity with electronics. Basic 3D modeling (SolidWorks) is not required but highly encouraged.
The Dynamics sub-team consists of a manager and 4 general members who will be tasked with modeling the trajectory, aerodynamics properties, and stability characteristics of sounding rockets. This will be done with the aid of aerodynamic literature, wind tunnel testing, and analysis tools such as MATLAB and STAR-CCM+. The culmination of this process will be a stable and aerodynamically sound rocket, a product of educated design choices. To accomplish this, members will be expected to consider all factors of a design problem, thoroughly document their work, and be detail-orientated while maintaining a high-level, systems engineering mindset. Members are expected to have an understanding of aerodynamic concepts, and a strong work ethic.
