Team BIOHAZARD Presents: Project CRUENTO

CRUENTO: Latin – to make bloody; stain with blood

Team Members Team Leader: Chris Pearson, Electrical Engineering Alicia Harris, Aerospace Engineering Andrew Brewer, Aerospace Engineering Greg Juarez, Aerospace Engineering Curtis Miller, Aerospace Engineering Shaun Valdez, Aerospace Engineering

Overview & Mission Statement Mission Statement: To ascertain how blood reacts to a near space environment. To Test: What are the conditions under which blood boils in a near space environment? What if there was an accidental tear or rupture in a pressure suit around 85,000ft. (~26,000m)? What are the differences between slow and abrupt releases of pressure on blood at that altitude?

Expected Results A liquid boils when the barometric pressure in the outside environment equals the vapor pressure of the liquid. If we can keep the blood near body temperature, then the atmospheric pressure at which this phenomenon occurs should be around 17.5mmHg. The Earth’s atmosphere reaches this pressure at about 26km. We are hoping to keep the heater close enough to the blood so that its temperature will be at or above 37°C. This way, we can see if the predicted altitude is accurate to calculation. We will find at what altitude this occurs by comparing data from our pressure sensor and the photographs we will obtain during the flight.
