“…8µm and in 2002 used a 3 . 4µm film for an unmanned balloon that reached a record breaking altitude of 53km (7) . Innovations in films and fibre development and in application for existing fibres such as Technora, Vectran and Spectra (8) will lead the way for future materials research.…”

Such studies were pioneering at the time. The experiment was conducted by M Montgolfier and it is reported that an account of his lift calculations (1) and the details of the 'experiment' were sent to the Académie Royale des Sciences on 2 July 1783 by the Minister of Finance. The event was so incredible that, apparently, local people who saw the balloon floating in the air believed that the moon had fallen from the heavens to herald the Last Judgment.Evidence for other unmanned flights includes the Nazca Indians of Peru and the Kongming lanterns in China in the Second century BC. Flying of egg shells was 'popular' in the 17th century and in 1709 the Brazilian born Bartolomeu de Gusmão demonstrated the propulsion of a ball to the roof by combustion. ABSTRACTOne hundred years on from the advent of aeronautics at Queen Mary, University of London, developments in lighter than air technology have progressed at a somewhat slower pace than the technology for heavier than air. Innovations afforded by the 'discovery' of helium, the development of the modern day hot air balloon and the application of new materials have all contributed to today's technical innovations. A review is given of the past history of lighter than air, a note is made of the current state of the art and a brief overview of future applications is discussed. The author's personal experience in long distance gas balloon flights is mentioned.

“…More recently, it has been proposed to use them to build a telecommunications network (Loon project). They consist of a gondola, a flight chain and an envelope, often a thin polyethylene film [2][3][4] reinforced with straps. There are different types of balloons, of different sizes and uses.…”

This article is devoted to the instrumentation, with optical fibres, of the straps holding the envelope of stratospheric balloons. This instrumentation is motivated in the first instance by the need to validate the numerical models used in the design of balloons. It must also be used to measure the temperature along the envelope in order to deduce the pressure field. It is shown at first that the optical fibres can be inserted inside a strap during its fabrication. Different kinds of insertion are considered, none of them perturb the industrial process. The instrumented straps were then submitted to thermal and mechanical tests and the distributed Brillouin frequency shifts were measured. We thus determined the type of insertion to be used according to the parameter (temperature or strain) to be measured and assessed the performance of the measurement chain.

“…In 2002, a balloon with a volume of 60,000 m 3 made from this 3.4-mthick¯lm lifted a 4.6-kg payload to an altitude of 53.0 km, which equaled the world record altitude at the time for an unmanned balloon (Yamagami et al, 2004). We then developed an even thinner lm with a thickness of 2.8 m (Saito et al, 2006); however, we encountered di±culties when trying to launch balloons made from this ultra-thin¯lm. Based on the lessons learned from three successive failures to°oat a 60,000-m 3 2.8-m-thick balloon, we reassessed all the key issues involved in launching an ultra-thin-¯lm balloon.…”

Since 2008, the Japan Aerospace Exploration Agency (JAXA) has carried out annual domestic balloon campaigns from Taiki Aerospace Research Field (TARF). Productive results have been obtained by many projects in academic¯elds such as atmospheric science, space engineering, cosmic-ray physics, and astronomy. In 2013, an 80,000-m 3 balloon made from a 2.8-m ultra-thin polyethylene¯lm reached an altitude of 53.7 km, equaling the world record for the altitude of an unmanned balloon. In 2015, JAXA carried out a balloon campaign from Alice Springs in Australia as a precursor of future sustainable overseas activities to compliment the domestic ones at TARF. In this paper, we discuss recent highlights of and future prospects for Japanese scienti¯c ballooning.
