List of Forlanini airships
This is a complete list of Forlanini airships designed and built by the Italian pioneer Enrico Forlanini from 1900 to 1931 (posthumously).[1] These, like the German Groß-Basenach semi-rigid airships, were the first to have the gondola attached to the envelope, to reduce air resistance.[2]
F.1 Leonardo da Vinci
- Designed: 1900-1901[3]
- Maiden flight: 2 July 1909
- Flights: 38, total distance 850 km.
- Longest duration: 90 minutes
- Length: 40 metres
- Volume: 3,265 cubic metres
- Propulsion: One Antoinette engine of 40 HP
- Maximum speed: 52 km/h
Construction started in 1900 collaboration with Cesare del Fabbro. Its first flight in 1909 was one year after the first Italian semi-rigid flight by Gaetano Arturo Crocco. Like all the Floranini airships, except the Omnia Dir, the empennage comprised groups of multiple planes at the poop and at the tail.[2]
F.2 Città di Milano
- Maiden flight: 17 August 1913[2][4]
- Flights: 43[2]
- Length: 72 metres[1]
- Volume: 12,000 cubic metres[2]
- Gas cells: 12[2]
- Propulsion: Two Isotta Fraschini engines of 80 HP each[1]
- Maximum speed: 70 km/h[1]
- Flight ceiling: 2400 metres[2]
- Useful payload: 5 tonne[2]
- Owner: Royal Italian Army (Regio Esercito)
- Fate: 9 April 1914 emergency landing during storm, then damaged by trees and terrain while moored. While attempting to deflate gas cells, caught fire and destroyed.[1]
F.2's gondola was divided in three compartments: the command cabin, passenger cabin, and machine room. For safety all the material was treated with a fire suppressant and the envelope was double-skinned.[2]
F.3
- Volume: 13,790 cubic metres[5]
- Propulsion: Four FIAT S.54-A engines of 80 HP each[5]
- Maximum speed: 80 km/h[2]
- Flight endurance: 24 hours[2]
- Useful payload: 6 tonne[2]
- Fate: built for the British government but due to World War I requisitioned by the Italian Army in 1918[3][5]
F.4
F.5
- Built: 1917[3]
- Volume: 17,783 cubic metres[5][7]

- Propulsion: Two FIAT S.76-A engines of 350 HP each[5]
- Flight ceiling: 20,000 feet (6,100 m)[3]
- Gas cells: 12[3]
- Payload: 22,000 pounds (10,000 kg)[8]
