Lebaudy Le Jaune / The Yellow

The company’s first airship, simply known as the Lebaudy, and dubbed by the French public “Le Jaune” (“The Yellow (One)”) because of the yellow colour of the lead chromate paint on its cloth exterior, was considered the most successful airship then in operation.

The Lebaudy Le Jaune (‘The Yellow’) dirigible was in the enormous Halles des Machines in Paris on 20 November 1903 in preparation for a flight over Paris. The flight got enormous publicity and a series of 30 (!) photographs / postcards were published to commemorate the event.

The Halle des Machines or Galerie des Machines was built specially for the Exposition Universelle in Paris of 1889. The Galerie des Machines had a span of 115 metres (377 ft) and height of 45 metres (148 ft). The whole building was demolished in 1910.

It had a 35 hp Daimler Mercedes engine driving two propellers. The ship was further improved on several trips, including one of 2 hours and 46 minutes. These activities continued in the following years, with the ship being rebuilt several times after crash landings in trees.

Lebaudy 190 / 1910 Morning Post

Two large dirigibles were ordered by Great Britan from France. The second airship, the Lebaudy, was purchased by the Morning Post newspaper as a gift to the nation, despite the fact there was at that time no shed large enough to house the 337 foot long craft. After protracted negotiations with the War Office agreement was reached to provide a new shen at Farnborough.

The Lebaudy had a gas capacity of 353,000 cu.ft giving a gross lift of 10.4 tons, powered by two 135hp Panhards. Colonel Capper had flown aboard her during trials earlier in the year in France and had reported favourably on her capabilities.

The airship was flown to England on 26 October 1910, maned by a French crew of seven and two representatives of the War Office including Major Bannerman who had succeeded Templer as superintendent at Farnborough. They crossed the coast at Cao Gris Nez, the airship easily overhauling the escorting destroyers at a speed of 35 mph.

After an uneventful flight of 5 hours 15 minutes the airship landed at Farnborough. On being taken to the shed the major in charge of docking became concerned that the top of the airship was too high to pass under the shed entrance, but was overruled by a senior officier who insisted the ship be walked in at once.

As the Lebaudy entered the shed the upper portion of the envelope was torn by the roof girder work, causing the ship to collapse and become a total wreck. It would appear that the dimensions of the ship supplied before the erection of the shed were different from the craft as completed, with the diameter being some 10 feet wider.
The wreckage was dragged into the shed and followed by an inquiry, during which the War Office refused to pay the purchase price to the Lebaudy Company, declared them negligent in not advising them of the increased diameter of the envelope. It was eventually agreed the Lebaudy Freres would foot the bill to repair and make the ship airworthy.

During the winter months the shed roof was raised by 15 ft, and a complete reconstruction was started. A test flight of the refurbished airship took place in May 1911 in the hands of the manufacturers with an all French crew. Soon after takeoff and following a short flight, problems with directional control were experienced, most likely due to the craft being badly rigged following certain modificatins to the suspension system.

The crew limped back to Farnborough where while attempting to land the airship lost control and dived into the round, crashing on to a house and becoming a complete wreck. There was no fire and the crew suffered only minor injuries.

Lebaudy Patrie / Krechet / Gerfalcon

In February 1907, with the Chief Military Engineering Directorate, was created a commission under the chairmanship of N.L. Kirpicheva, which received the task to run the necessary experiments and to build a large dirigible. To the works were drawn the researchers: N.E. Zhukovsky, A.N. Krylov, V.V. Kuznetsov, E.S. Fedorov, K.A. Antonov, D.M. Smirnov, and others. The project they developed was under the direct management of N.I. Utesheva. Construction was somewhat drawn out, and only on July 30, 1910, the airship “Krechet” performed its first flight. It was the largest airship at the time.

The Patrie employed a non-combustible shield over the motor, for the protection of the envelope: its steering wheel was in front and the motor about in the middle of the car. The gasoline tank was under the car, compressed air being used to force the fuel up to the motor, which discharged its exhaust downward at the rear through a spark arrester.

The semi-rigid Lebaudy Patrie was used for training by the Russian Empire as the Krechet (Gerfalcon).

The Patrie was destroyed by a storm.

Lebaudy La Republic / Swan

Built in 1908, it was the first airship which the Russian War Department ordered abroad (in 1909), and named “The Swan”. The airship perfected the overall suitability for the role of airships in the fighting. The results were disappointing as in the case of air defense, airships of the attacking force quickly transformed into a huge target. The airship was assigned only the role of reconnaissance.

The semi-rigid La République crashed in September 1909 and all four crew members were killed.

Lawrence Aeriator

Little is known about this complicated machine, which was designed by George A. Lawrence of Sayre, Pennsylvania. It was claimed to have flown during secret tests, first on 1 October 1907, and then on 11 October. It’s not clear if it was crewed or not, however the inventor said he had plans to build a larger machine, which would be powered by a 60 hp engine and capable of carrying three people. In 1908, Lawrence entered into a business relationship with Gustave Whitehead and formed the Whitehead Motor Works.

Lauer L.II Dädalus

A German school biplane built in spring 1912, powered by a 55 hp Argus, Richard Lauer built this biplane in 1912 and was permitted to test the aircraft at the Exerzierfeld Halle-Beesen, where he managed “some long flights”. He also set up a hangar and wanted to open a flight school that summer but unfortunately he crashed and destroyed the aircraft in June. Lauer suffered severe injuries that presumably prevented him from ever flying again.
