Derived Lenticular (L) Types
Derived L types stem from the StratRaft and AeroRaft aircraft designs. In order to pursue development, the SkyLifter business was started in 2008 with a long term goal to be an operator of the AeroRaft type (without a rotordyne) to:
- Undertake aerial crane duties with up to 150 tonne payloads (needing traditional load exchange methods) and
- Provide global aerial hotel cruising services.
These goals were published by SkyLifter and in various articles, also calling the aerial crane version a SkyLifter. However, itís called SkyHoister here to avoid confusion with SkyLifter's name as a business and other Luffship types. Also, because SkyLifter may not be the eventual developer for some Luffships; where 'SkyLifter Malaysia' (an independent company) was started in late 2010 for development purposes of the Mk 1 SkyRover.
For an introduction to Luffships designed for SkyLifter, see the downloadable briefing.
Design of further L type Luffships intended to enable a progressive development approach thus were undertaken, as follows:
R/C Models (LTA Drones)
- SkyBirds: LS-L2, LS-L3 and LS-L5 (Mk 1 SkyRoamer)
Tethered (T) or Captured Aerostats
- SkyScreens: Mk 1 (LS-LT18-V1 & V2) and Mk 2 (LS-LT15-V1)
- SkyElevators: Mk 1 (LS-LT15-V2), Mk 2 (LS-LT20) and Mk 3 (LS-LT40)
- SkyGasometer (LS-LT30NG) as a demonstrator for natural gas storage and handling
Dirigibles that may be manned
- SkyRovers: Mk 1 (LS-L20) and Mk 2 (LS-L25)
- SkyGasPorter (LS-L30NG) as a demonstrator for natural gas transportation
- SkyLugger (LS-L50) for up to 5 tonne payloads
- SkyPorter (LS-L100) for up to 50 tonne payloads
- SkyHoister (LS-L150) for up to 150 tonne payloads
- Just click on the various versions for information about them. However, information about some has been withheld to focus in a doable/realistic way on the approach needed to develop aerial cranes, but available from contact - see below.
- 'Load exchange' is the procedure to replace payload weight with ballast or vice versa, to maintain constant airborne weight (necessary to counter buoyancy) when picking payloads up or setting them down. For two documents addressing load exchange, which discuss the issues, see the downloadable paper and/or dissertation.
- Although SkyLifter companies in Australia & UK enabled the LS-L3 & LS-LT18-V1 to be produced, and where the LS-L20 was being developed by the Malaysian company from LTA Solutions IP, arrangements are possible with other developers who agree to cooperate with both LTA Solutions and relevant SkyLifter businesses or their successors.
