High Altitude Balloon Payload Design Program
(Summer 2012)



                   

Program Overview

    In this project, 6 female engineering students will work as part of an interdisciplinary project team to design a high altitude balloon payload. The payload will collect environmental information during the flight to allow subsequent science experiments to be carried safely. The payload will be designed to adhere to the interface guidelines from the High Altitude Student Platform (HASP) balloon launch program that is jointly administered by the NASA Wallops Balloon Program Office and Louisiana State University for a future flight. At the end of the summer program, the payload will be test flown on a MSGC BOREALIS balloon platform to an altitude of 100,000 feet.

    The overall goals of this program are to engage underrepresented groups in STEM and expose undergraduate engineering students to an interdisciplinary design project which is accomplished using the principles of systems engineering. Program Flyer

Engineering Design Process

    1. Mission Architecture

    Mission Objective: To collect measurements at high altitudes of atmospheric temperature and pressure, the internal temperature and dynamic movement of a payload that meets HASP flight requirements.
     
    Budget: $500
     
    Schedule: 8 Weeks, (6/4/12 - 7/27/12)
     
    The Design Team: Jen Hoff & Kate Ferris : (Electrical System)
    Kaysha Young & Emily Bishop : (Mechanical System)
    Allison Figueira & Makenzie Guyer : (Computer System)
     

    2. Mission Requirements

    Functional Requirements: - Log/Store data from the sensors on a non-viotile storage device.
    - Power Sensors and any electronics needed to run these sensors.
    - Protect the system from environmental conditions.
    - Protected from the impact upon landing/jerk from the balloon pop.
    - Provide state of health information of the system.
     
    Performance Requirements: - Consume 7 watts in order to accurately represent the research team's thermal output.
    - Log data from the temperature/pressure sensors at a rate of 1 measurement per second.
    - Log data from the accelerometers at a rate of 3 measurements per second.
    - Provide insulation to keep the internal temperature between -40 C and 60 C.
    - Provide at least 4 hours of power for the duration of the setup, flight, and recovery time.
    - Withstand an vertical force of10 g and a horizontal force of 5g.
    - Withstand vibrations up to ____- Hz.
     
    Physical Requirements: - Must weight 1.62 kg.
    - Maximum Total Volume: 15 cm x 15 cm x 30 cm.
    - Mechanically interface with the HASP payload plate in addition to the BOREALIS system.
     
    Reliability Requirements: - Must be able to survive preliminary tests and two launches.
