Luffships

These are new LTA aircraft (mainly airships) designed by Charles Luffman. They include:

Concept drawings, specifications and associated supporting documents are available for each type.

Projects:

To review the projects click on the links below. Note: Information about C, F, H N and S aerostat forms has been removed to focus on new O-D types.

If more information about any of the different types is desired, its available from contact.

Shape study of different forms with equal volume.

Note:

Airships are propeller driven motor powered dirigible (so steerable/controllable) balloon systems! For comparison of the different types (C, L & S) see the illustration drawn to scale with equal volumes. The C & L forms have an aspect, slenderness or fineness ratio = 4 = length/diameter for C types & diameter/height for L types. This ratio also is known as the prismatic coefficient (a block ratio).

However, when considering aerodynamic drag, overall size has an effect; where the C form is somewhat bigger than the others, because it volumetrically is a significantly less efficient gas container - so has greater wetted surface area. This should not be overlooked!
