UP, UP, AND AWAY!CRITICAL DESIGN REVIEW

Ty Bailey, Soo Park, Cameron Coupe, Trevor Arrasmith, Carolyn Mason, Sam Frakes, Brandon Harris, Peter VanderKley

MISSION OVERVIEW The objective of team Up Up and Away is to prove the

possibility and efficacy of a balloon mounted mechanism for cloud seeding

Cloud seeding has never been attempted from a balloon mounted device Could prove the feasibility and possible cost

effectiveness Given the ability to use enough of the correct

substance for cloud seeding, a balloon mounted mechanism will be feasible and economic

Cloud seeding can lift droughts and increase precipitation. A cheaper alternative to traditional methods can reveal further opportunities

REQUIREMENTS FLOW-DOWN CHART Mission Requirements Level 0Requirement Number

Requirement Derived from

Objective 1.0

Team Up Up and Away will prove the possibility and efficiency of a balloon-mounted mechanism for cloud seeding.

Mission Objective

Objective 2.0

Team Up Up and away will test the effectiveness and reliability of the funnel dispersing system of the BalloonSat.

Mission Objective

Objective 3.0

B.O.S.S will collect the data of outside, inside temperature, humidity, pressure, and the speed of wind during the flight.

Objective 4.0

The integrated GoPro camera in B.O.S.S will record the flight and also the cloud seeding process.

Mission Requirements Level 1Requirement Number

Requirement Derived from

Objective 1.1 Team Up Up and away will prove that given the ability to use enough of the correct substance for cloud seeding, a balloon mounted mechanism will be feasible and economic.

Objective 1.0

Objective 2.1 Using the two integrated funnels and servos, the BalloonSat will disperse Sodium Chloride at two different altitudes.

Objective 2.0

Objective 2.2 The mechanism to release the powder will consist of an oscillating triangular aluminum plate controlled by a Servo, which will block the flow of salt out of the container except when prompted to move.

Objective 2.0

Objective 2.3 The base plate on which the oscillating plate will rest will also be made out of a 3mm thick aluminum sheet and will assure that the triangular piece can oscillate smoothly against its surface.

Objective 2.0

Objective 2.4 The funnel will be supported by cross wires so that it does not fall over or get shaken or broken in flight. We will make sure that the salt will not fall out of the cone by securing a lid on the top of it.

Objective 2.0

Objective 3.1 With the GoPro facing down, it will attempt to capture the process of cloud seeding.

Objective 3.0

Objective 4.1 Using the arduino and the sensors, the BalloonSat will record the data for temperature, humidity, pressure, and wind speed during the duration of the flight.

EXPECTED RESULTS We Expect To:

Record accurate information from all sensors Confirm the proper functioning of mechanisms (namely

the servos) Observe the powder as it is released

We Hope To: Observe (with GoPro and from ground) a red cloud

forming after powder is released This observation would confirm both function and

effectiveness of our release system
