Modern Airships – Part 2

1. Introduction

“Modern Airships” is a three-part document that contains an overview of modern airship technology in Part 1 and links in Parts 1, 2 and 3 to 79 individual articles on historic and advanced airship designs. This is Part 2.  Here are the links to the other two parts:

You’ll find a consolidated Table of Contents for all three parts at the following link.  This should help you navigate the large volume of material in the three documents.

Modern Airships – Part 2 begins with a summary table identifying the airship concepts addressed in this part, and concludes by providing links to 25 individual articles on these airship concepts. A downloadable copy of Part 2 is available here:

The links to the individual articles are at the end of this document.

I hope you’ll find the Modern Airships series to be informative, useful, and different from any other single document on this subject.

2. Specific airships in Part 2

The airships reviewed in Part 2 are summarized in the following set of tables.  There are many heavy-lift cargo airships in these tables. In addition, there are several solar-powered airships and sub-scale airships that demonstrated novel means of airship propulsion.  Links to the individual articles on these airships are provided at the end of this document.

Among the airships in the above tables, the following full-scale airships have flown:

  • Project Sol’R Nephelios solar-powered airship
  • Solar Ship 20-meter Caracal prototype
  • Solomon Andrews’ Aereon I and II variable buoyancy propulsion airships (in the 1860s)

In addition, the following sub-scale demonstrators have flown:

  • Festo b-IONIC Airfish (demonstration of ionic propulsion)
  • Phoenix and AHAB (demonstrations of variable buoyancy propulsion)

Among the airships in the above tables, several airships are likely to receive their airworthiness certification in the next several years. The leading candidates identified in Part 2 are:

  • Flying Whales: The LCA60T prototype maiden flight is expected to take place in 2021, and the firm appears to have the funding needed to enter full-scale production.
  • Varialift:  The ARH-PT prototype’s first “float test” is expected in 2019.  The first ARH 50 roll out is expected in 2021, with a 24-month certification process before commercial deliveries begin.
  • Euro Airship: Production-ready drawings exist for the Corsair and the larger DGPAtt.  When funding becomes available, they’re ready to go.
  • Solar Ship: The 24-meter Caracal semi-buoyant, inflated wing airship and the larger Wolverine semi-buoyant aircraft are expected to receive Canadian certification, possibly by 2020 – 2021.
  • Egan Airships:  The PLIMP drone and Model J plane / blimp hybrids that have started their FAA certification processes.

These airships will be competing in the worldwide airship market with the leading candidates identified in Part 1, which may enter the market in the same time frame:

  • Lockheed Martin: LMH-1 hybrid airship
  • Hybrid Air Vehicles (HAV): Airlander 10 hybrid airship
  • Aeros Aeroscraft ML866 / Aeroscraft Gen 2: variable buoyancy airship
  • Volaris V932 NATAC: semi-buoyant, inflated wing airship

The early 2020s will be an exciting time for the airship industry.  We’ll finally get to see if the availability of several different heavy-lift airships with commercial airworthiness certificates will be enough to open a new era in airship transportation. Aviation regulatory agencies need to help reduce risk by eliminating regulatory uncertainty and putting in place an adequate regulatory framework for the wide variety of advanced airships being developed. Customers with business cases for airship applications need to step up, place firm orders, and then begin the pioneering task of employing their airships and building a worldwide airship transportation network with associated ground infrastructure.
