SkyScreens: Mk 1 (LS-LT18-V1 & V2) and Mk 2 (LS-LT15-V1)

SkyScreens are low captured (tethered) lenticular aerostats, designed with a mooring restraint system that allows them to rise under control from the ground to a maximum height of say 20 m for light-show display and projection purposes as braced static overhead aerial screens (providing an attraction at events, seen from afar and viewed from the ground) recovered to ground level when not in use for safe keeping. As primarily non-rigid fabric structures, they would be mostly air inflated and pressure stabilised to maintain form, but have enough helium for displacement purposes – enabling excess buoyancy to counter aerostat weight and impart sufficient tension into restraint lines, preventing them from slackening against aerodynamic wind loads.

Projection onto the aerostat’s lower surface (an essentially large flat disk area) is best undertaken with systems on the ground. However, the projectors also can be carried by the aerostat if desired, but needs additional expensive helium, complexity and safety aspects to be covered (increasing cost). Naturally, the aerostat thus may carry lighting and other systems (e.g. cameras) for further purposes.

The designs stem from mooring arrangements for similar lenticular aerostats used by dirigible Luffship types and the need to develop these arrangements in an assured way through field tests before attempting free flight. SkyScreens thus were arranged as useful products for just ground use, perhaps later upgraded for dirigible flight purposes.

Types designed include: Mk 1 (LS-LT18-V1 & V2) and Mk 2 (LS-LT15-V1), as shown respectively above. They also may be used as big parasols or rain shelters (i.e. a large floating roof) with a stage below.
