October - changes in technology in the gliding industry

29/10/2016

0 Comments

 
Dramatic film taken from the cockpit of a competing glider racing another at up to 250km/hr during a gliding competition in Chile began our October session, fitting in well with ‘The Sky’s the Limit’ theme of this year’s Benalla Festival in the lead up to the World Gliding Championships in January.  
​
Guest speaker, glider pilot Tim Shirley, gave a fascinating presentation on changes over time in the devices used to track the position and performance of gliders, particularly during competitions.  
Since the advent of GPS it seems that the capacity for occasionally corrupt practices during competitions has been virtually eliminated!  

Certainly the gliders coming to Benalla in January - which carry price tags from about $150,000 to $500,000 - will have the latest tracking equipment.  Perhaps more importantly they are much lighter than previously because they are made of kevlar and carbon fibre and travel  50 metres forward while only descending one metre.
 
Tim’s session clearly provided rich ground for reminiscing by those with past experience of gliding.  It also provided us all with a more informed base on which to understand the experiences of those who will be flying over Benalla in January.
 
During question time Tim, an experienced competitor, was asked if he would be gliding during the competition.  He jokingly set us straight saying there are teams of six pilots from each country, and he’s not exactly the Michael Schumacher of Australian Gliding.
 
An intriguing answer resulted from the question ‘Why have so many of the advances in gliding technology taken place in Germany’?  It seems that after World War I the Treaty of Versailles contained provisions restricting the production of powered aircraft in Germany.  The result - the attention of German aviators changed direction - to gliding.
​ 
Our final session will be on November 9th when Bill Parris will introduce his extensive watch collection as part of a ‘Show and Tell’ session in which we will all bring along an item or two which demonstrate changes in technology over time.  This will be followed by time for working groups ‘Tech Savvies’ to discuss incorporating the Internet of Things in next year’s sessions and ‘Mentors’ to begin planning the Tech Savvy Drop In for 2017.

September news 

1/10/2016

0 Comments

 
​Another thought provoking TED talk, this time ‘What can save the rainforest?  Your used cell phone’, set the scene for our September session.
 
Class member Les Rodgers followed with a presentation highlighting the main changes in communications technologies (including broadcasting) and their impact during his career as an engineer.

Originally from Queensland, Les spent most of his working life with Telstra and its forebears, apart from a period with the Weapons Research Establishment in South Australia.  His working life began at the time of switchboard technology and included time in New Guinea; involvement with rocket launches at Woomera; dealing with governments at high levels while national manager of projects including the spread of television transmission to country areas and broadband to rural Queensland ; the replacement of the television transmitter in Hobart; and speaking at a Senate Estimates Committee leading to a mention in Hansard.    

What a rich career – thank you for sharing your journey with us Les.
Next month, IT specialist Tim Shirley will continue the theme of changes over time in technology, presenting on changes over time in the Gliding Industry, a very pertinent topic with the World Gliding Championships being held in Benalla in just a few months.
 
At our final meeting in November, Bill Parris will lead a ‘Show and Tell’ session in which we will all bring along an item or two which demonstrate changes in the technology over time.  Bill is going to bring along his extensive watch collection, while the rest of us are thinking deeply about just what we might bring along. ​​
