The Airship Association believes that Lighter than Air Vehicles (LTAV) have the potential to provide viable and cost-effective aerospace platforms for a number of applications which are currently undertaken by a variety of more conventional forms of transport. LTAVs should not be considered a replacement for conventional aircraft or ships, but complementary; part of a comprehensive transport network which reduces the economic cost of transport in certain areas.
While we are pleased with the response to the call for papers, we have been asked to extend the deadlines for submission of abstracts to the papers committee.

CALL FOR PAPERS
Despite many false starts the airship industry faces challenging opportunities in the near future. Opportunities for proposed cargo airships in Alaska, northern Canada and Russia have recently been extensively promoted and offer exciting challenges. Moreover, Brazil has also recently declared its intent to build and fly cargo airships. Market studies also show that globally there is a viable airship industry. Numerous issues have to be addressed in sustaining an effective airship industry; the convention will focus on the issues.
In partnership with Deutsche Gesellschaft für Luft- und Raumfahrt (DGLR) the Airship Association will hold the 10th Biennial International Airship Convention & Exhibition in conjunction with Aero Friedrichshafen from 17th to 18th April 2015 in Friedrichshafen.
A new book, Principles of Aerostatics, is now available, and will be reviewed in the September issue of Airship. The book presents the complete theory of static lift for airships, aerostats and balloons. Concepts are laid out, and building on the derivation of temperature, pressure, density and humidity in the atmosphere and the gas laws, formulas for static lift are derived. The variation of lift with atmospheric and airship parameters, climb and descent, and flight above pressure height are then explored. Both SI and United States Customary Units are employed throughout, and worked examples and calculator programs are provided. That may sound daunting, but the mathematical process can be followed by a reader with an understanding of high school algebra.
A summary of the attached paper is published in the June edition of AIRSHIP, No. 184. As the paper is approximately 100 pages long, we have elected to provide a complete copy for download from here, with a shortened summary reproduced in the journal.
Therefore, this paper is designed to be accessible to members in receipt of the June edition of AIRSHIP only. Anyone may download it, but you will require a password to access the file. The password can be found on page 23 of AIRSHIP No. 184.
Any non-members who may wish to purchase a copy of the journal, please email or write to the Hon. Secretary (firstname.lastname@example.org). The retail price is £ 12 +p&p (or equivalent in other currencies).
The June Edition of 'AIRSHIP' has just been sent to the printers. With a bit of luck, a fair wind and not too many paper jams, members should receive their copy in time for the forthcoming AGM. :)
The Airship Association Journal, 'Airship', has been evolving over recent months under the excellent stewardship of Paul Adams. Paul recently passed the editor's baton to a committee comprising Members of Council, the governance group within the Association.
Not only is the Journal undergoing some restructuring, but The Airship Association itself, with Council now under the Chairmanship of Rob Knotts, is at the start of an intensive period of renewal, restructuring, development and growth.
The 2014 Annual General Meeting of the Airship Association will take place
from 6.30 to 9 pm on Thursday 24 April 2014
Friends House (London) Hospitality Ltd
173 Euston Road
London, NW1 2BJ
The Friends House is opposite Euston railway station
Following the meeting Air Commodore W Tyack CBE FRAeS RAF (Ret’d) the President Elect of the Royal Aeronautical Society will make a presentation.
AIRSHIP ASSOCIATION’S REGATTA AND SYMPOSIUM
By the Association Chairman, Rob Knotts
The word ‘airship’ carries a lot of historical baggage. The same tired old pictures of the Hindenburg crashing in flames in 1937 get trotted out by the news media at every mention of the word. The Airship Association believes it is now time to see beyond this 75 year old tragedy and to look again at a technology that is much misunderstood but which in reality has great potential.
