Nine aspects of this work are covered: 1) inflated, rigidized tubes, 2) active control experiments, 3) photogrammetry, 4) laser vibrometry, 5) modal tests of inflatable structures, 6) in-vacuum modal tests, 7) tensioned membranes, 8) ... were inflated, followed by the reflector canopy. L'antena es va inflar correctament, separant-se de l'Spartan-207, abans de tornar a entrar a l . It is anticipated that the harsh environment of space, intense temperature differentials and micrometeorite bombardment, will most likely threaten the pressurized satellite . Experimental demonstrations and study efforts have continued since the early 1960's. With the latest progress in transmitter and receiver technology, the next natural step is to beam power from earth to space. inflatable-deployable antenna experiment development flight hardware large space structure low weight excellent example space environment space access meaningful orbital assembly capability space-based antenna current mtenna-user requirement inflatable-deployable structure different application current concept usable aperture . The experiment was part of the Shuttle Pointed Autonomous Research Tool for Astronomy (SPARTAN) series that provided short duration, free flight opportunities for a variety of scientific studies. The reflector deployed to expected geometry, but an underestimation of residual gas at packaging led to uncontrolled dynamics in the deployment process. The officially designated Inflatable Antenna Experiment was released in 1996 as part of a Spartan satellite - which contains many scientific experiments.

About the size of a tennis court, the Inflatable Antenna Experiment (IAE) was the first space structure of its kind, laying the foundation for future work on inflatable satellites, telescopes, and even astronaut dwellings. High-resolution video photography In 1996, the STS-77 space shuttle mission deployed the Inflatable Antenna Experiment (IAE). In the NASA Inflatable Antenna Experiment (IAE) [10], unexpected deployment behavior was attributed to residual air. First the IAE struts Covers advancements in spacecraft and tactical and strategic missile systems, including subsystem design and application, mission design and analysis, materials and structures, developments in space sciences, space processing and manufacturing, space operations, and applications of space technologies to other fields. 2/17/1973. The inflation procedure lasts about 5 minutes, bringing the antenna to its full size of 90 feet by 50 feet, or the equivalent size of a tennis court. Primary payloads, all located in the cargo bay, were the SPACEHAB-4 pressurized research module; the Inflatable Antenna Experiment (IAE) mounted on Spartan 207 free-flyer; and a suite of four technology demonstration experiments known as Technology Experiments for Advancing Missions in Space (TEAMS). This paper describes the status of NASA's Inflatable Antenna Experiment (IAE) and a brief discussion on potential future applications.
