H.A.P.L.E.S.S

In this meeting

• Finalise teams• Introduce you to your team leaders• Notices – MechEng workshop • High Altitude Balloon Briefing • First team activity – Decide team

name• Discuss ideas/brainstorm/logistics

TEAM ALHPA ARISE!!!!!!!!

TEAM OMEGA ARISE!!!!!!!!

Using MechEng WorkshopThe Department of Aeronautics has arranged for a course to be held in the

Mechanical Engineering Student Workshop, offering basic introductory training focusing on the use of general workshop machines, such as lathes,

mills and drills. The duration of the course is 2 consecutive days. After completing the course, users will have enough basic training to be

authorised to use the workshop machinery in the Mechanical Engineering Student Workshop during 'free-to-access' timetabled slots throughout the

week.

Please note;1. The course is open to PG students and 3rd/4th year UG students.

2. Places are limited3. The date of the course (3rd and 4th Jan 2012)

Approaching your project

Teejay sadly is not on a team but let us see how he would approach this kind of project. So Teejay any bright

ideas.

Just 1…..Rockets

Break it down

High Altitude Balloon Consists of a:• Balloon filled with Helium • Parachute• Cords• Payload Bay

Balloon

• Understanding your balloon – give it a cuddle (POP)

• Lifting weight : will this affect you ascent rate, maximum altitude ?

• Price

Parachute

• Material • Descent rate: dependent on size, shape,

number of cord lines, number of parachutes,

• Possible to make it directional ?

Chord

When your balloon bursts very important.

• Stiff/ Stretchy and if so how long should it be ?

Payload When all is said and done this is the most complex

and important part of the project .Structure : • Outer material : Strong, Light, Insulated ? • Size/Dimensions : Streamline of Bluff • Internal material: Insulation is important • Arrangement: Camera, GPS module

Payload When all is said and done this is the most complex

and important part of the project .Electronics• Central processing unit: Arduino, Raspberry Pie• GPS module: Range/power, reliability, directional,

how it works, ground equipment, cost, accuracy.• Camera: Type, Picture/Video, Storage, Quality,

combine with GPS ?

Other Considerations

• What happens if you lose it ?• What if it falls in to the sea • What if it hit France (if you have a mobile phone

you can call it) ?• Loads more but have to finish this presentation

before 6….http://ukhas.org.uk/general:beginners_guide_to_high_altitude_ballooning http://randomsolutions.co.uk/Random_Aerospace/Welcome.htmlhttp://ukhas.org.uk/guides:faq

So how will you do it• Split up the project and certain

amounts of people tackle different parts

• Split up the project and tackle each part all together in joint team effort on each part

• Hakuna matata it will all work out

This is your project you complete it how you see fit, you can take any

advice we offer or ignore us and build some epic never seen before

monstrosity

Ultimately

JUST ENJOY and I WISH YOU LUCK
