(Semi-rigid)= Up to date, these vessels have been designed by Major Gross and Oberingenieur Basenach. The utmost secrecy is observed as to their details. The system of employing 2 ballonets has been borrowed from the _Parseval_ type, and presumably the _Parseval_ system of working the automatic valves has also been adopted. In all other features, these ships appear to resemble the French _Lebaudy_ type, the shape of the hulls being rather better.

When the "Motorluftschiff Studien Gesellschaft" was formed at the instigation of the German Emperor, a committee was formed to acquire an experimental airship of the most promising type. Major Von Parseval's first airship was selected, and since that time the above company has confined itself to improving this type, and to making exhaustive and costly researches, all of which have been embodied in successive ships. The characteristic feature of every one of these craft is its unequalled portability. Almost all other so-called Non-rigid vessels distribute the load by means of a long girder which also serves as a car. This girder is awkward to pack up and transport. Parseval uses a comparatively small car, and distributes the weight by hanging it further below the balloon than usual, and also by using 2 ballonets which are placed one near each end of the gas bag. These 2 ballonets enable the ship to be trimmed by merely pumping air into either at the expense of the other. Another essential feature of the type is the system by which the valves are worked automatically. At the present time there is no other system of valve working so reliable as this. A third essential feature of the class is the use of a swinging car, in such a manner that pitching, due to alterations of propeller thrust, is automatically checked by an alteration of the position of the centre of gravity. A fourth feature is the use of limp propeller blades. A propeller of this type is very easily packed up. The shape of these vessels is in accordance with the experiments of Professor Prandtl.

(Parseval class.) [Illustration] ~Length,~ 197 feet (60 m.) ~max. diam.~ 31 feet (9.4 m) ~capacity,~ 113,000 c. feet (3,200m cubed) ~lifting power,~ 7,800 lbs. (3,583 kgs.) ~Gas bag.~--Cylindrical, with semi-conical front. Of rubber-proofed material in longitudinal strips. Pressure in ballonets and gas bag, 30 mm. of water. ~Motor.~--One 85 h.p. Daimler. ~Fuel.~--700 lbs. (325 kg.) 88 gallons (400 litres) ~Speed.~--20 m.p.h. (32 k.p.h.) ~Propeller.~--One 4-bladed. Semi-rigid Parseval. This vessel was somewhat altered on being bought by the Society. Her essential principle is that she can be taken to pieces in a few minutes, and carried in a truck. Her main feature is that she has a ballonet at each end. This is described in the case of type A (_P.L. 2_). This class rise with the forward ballonet empty, and inclined up by the bow. The propeller is similar to that of _P.L. 2_. The car also is mounted on wire runners. She was originally 4,000 m cubed. capacity. Built 1908. Station: Bitterfeld. The car is at present in Deutsches Museum, Munich. PARSEVAL P.L. 2 = P. I. Military. (1908.) [Illustration] Built by the "Society for the Study of Motor Air Ships," and taken over by the German War Office. ~Length,~ 197 feet (60 m.) ~maximum diameter,~ 34 feet (10.40 m.) ~capacity,~ 111,270 cubic feet (4,000 cubic m.) ~lifting power,~ 9,200 lbs. (4,180 kgs.) ~Gas bag.~--Front end semi-ellipsoidal with semi-axes 15.4 feet (4.7 m.) and 11.8 feet (3.6 m.), from which it increases to its maximum diameter. This is maintained for about two-thirds of its length, when it begins to taper to a point at the stern. Made of 2 layers of transverse strips of rubber proofed material, crossing each other diagonally. Fitted with a tearing strip. ~Ballonets.~--One at each end, together amounting to about one-quarter of the total capacity. Owing to this disposition, the trim can be altered, and steering effected in the vertical plane by filling either more than the other. Pressure in the ballonets and gas bag, 20 mm. of water pressure. ~Motor.~--4-cylinder 85 h.p. Daimler placed at one side of the car to give more room. 1,000 to 1,200 r.p.m. ~Propellers.~--12-1/3 feet (3.75 m.) diameter, 250 to 300 r.p.m. 4-bladed, the blades being of peculiar construction. When stopped, the fabric of which they are made hangs down limply; when running, these flaps fly out under centrifugal force. ~Speed.~--27 miles per hour. 43 kilometers per hour. ~Car.--Length~, 22-1/3 feet (6.8 m.) Width 4.1 feet (1.22 m.) Made of nickel steel, U bars, screwed together so as to take the pieces rapidly. The sides are lattice girders. The whole is boat shaped and covered with canvas. Contains motor, chart table; trail rope 480 feet (146 m.) long, weighing 220 lbs. (100 kg.) Wheel for horizontal steering at the bow. 110 gal. (500 litre) cask of petrol on the girders at the after point. 41 feet (12-1/2 m.) below the gas bag. It is capable of swinging horizontally on wires running over rollers. Whereas without this device a forward swing of the car would lift the nose to a possibly dangerous extent, the free motion of the car shifts the centre of the gravity forward and so preserves stability. ~Steering.~--In vertical plane, by altering the trim. In horizontal plane, by a rudder of 80.7 sq. feet (7-1/2 m squared) immediately behind the vertical plane. Two fixed horizontal planes are placed at the rear end of the gas bag above the central line. [Illustration: PARSEVAL II.] ~Table of weights~:-- Gas bag 1,653 lbs.

Military. S.L. I. (1911.) H. Heinrich Lanz, Rheinau bei Mannheim. [Illustration] ~Maximum length,~ 426 feet (130 m.) ~maximum diameter~, 60-1/2 feet (18.40 m.) ~volume~, 706,000 c. feet (20,000 m cubed.) ~Total lift.~--About 20 tons (20,000 kgs.) ~Useful lift.~--About 5 tons (5,000 kgs.) ~Gas bags.~--These are of great strength and of unusual shapes, made to fit the interior, which is encumbered with cross stays. All but two of the bags are always full, and when the gas expands it flows into the remaining two, which are nearly empty at sea level, and full at 6500 feet (2,000 m.) A centrifugal pump is used for distributing the gas. There are 14 gas bags. ~Motors.~--2 Maybach of 270 h.p. each. The propellers are at the ends of the car, driven through 1 set of reduction gear. ~Speed.~--38-43 m.p.h. About 59-64 k.p.h. ~Propellers.~--2 aft. Also 1 with its axis vertical. ~Steering.~--Vertical and horizontal rudders at both ends of the ship. Also see Propellers. Remarks.--Two of these ships were under construction, and one was to be presented and one sold to the German government. The hull is built of special 3-ply wood made of Russian white fir; this wood is pressed into channel bars, angle bars, and all other requisite shapes. The strength of the hull is such that it can be supported at the ends without damage; its lightness is such that although the ship is nearly half as large again as _Zeppelin II_, yet the hull weighs about 3 tons less. Designed by Prof. Schuette. In 1910, structural defects were found in _Schuette I_ when the loads were applied. This has necessitated extensive alterations and much delay. In 1911 it was completed, and sold for L25,000 to the German Army. SCHUeTTE-LANZ 2. Military. S.L. II.

Graf von Zeppelin, Friedrichshafen. The features of this type are--A rigid framework of aluminium, a number of drum-shaped gas bags, and a thin outer cover. [Illustration] At the end of March, 1913, the total of _Zeppelins_, limit and building was 16, including one (number 18) for Austria. Of these several had come to grief in various ways, and the actual total at the date mentioned, was:-- ~8 effective~ = 4 Army (of which one _Z4_ was still on trials), 1 naval and 3 private. 3 completing or building = 1 naval, 1 private and 1 for Austria. Others projected but not actually in hand. All are on the lines of the above plan, differing only in minor details, such as the provision of a cabin amidships, etc., and in dimensions.

Venice. Verona. ~ITALIAN MILITARY AVIATION.~ ~ORGANISATION, etc.~ The _Battaglione Aviatori_ has its headquarters at Turin. In July, 1912, it was re-organised along the following lines:-- 1 command at Turin. 1 flying work. 1 technical work. 2 troop duty. 6 at the aviation schools, with a certain number of mobile squadrillos. The recognised grades are:-- _a.a.p._ aspirante allievo (learners). _a.p._ allievo pilota (certificated pilots). _p._ pilota militare (superior military brevet). In flying work the superior pilots are mostly using _Bleriots_; the ordinary pilots _Bleriot-Caproni_, _Bristol_, _Antonis_, _Deperdussins_ and _Voisins_. The technical section chiefly supervises the theoretical instruction of the _a.a.p._ The 2 companies on troop duty practical work, preparation for the schools. ~FLYING SCHOOLS.~ The military schools are:-- ~Aviano.~--Central school. Size about 5x2 kilometres. Sheltered from all winds except westerly, by banks of trees. Numerous hangers. ~Mirafiori (Turin).~--Mixed military and civil school. Hangers. School machines confined to _Asteria_, _Bleriot_, _Nieuport_ and _Savary_ types. ~Pordenone.~--School for superior brevets. Treeless plain. Principal school machines _Breguets_ and _Farmans_; but some _Bleriots_ and _Caproni_. ~S. Francesco al Campo.~--_M. Farman_ machines. At present for officers trained in France. ~Somma Lombarda.~--Camp school for _Nieuports_. ~Venaria Reale.~--Formed late in 1912. _Bristol_ monos for certificated pilots. ~GENERAL TRAINING.~ 50 officers in training during the first quarter of 1913. Aspirants commence with instruction in the theory of heavier than air machines, resistance of material and particular instruction in the various type of aero motors in use. They are taken for flights as passengers. All then go to the training camp about 80% for monoplane work, the remainder for biplanes. Monoplanes. Special attention paid to teaching _Gauchis Dessent_. Biplanes. Much shorter course. Principal feature: _Vol Plane_. For the _military brevet_ the examination is most comprehensive, special attention is paid to flying in wind, manoeuvring, climbing, good landings without inconvenience to passengers, cross country flights, etc. The course is generally modelled on war experiences. ~TOTAL FLYING STRENGTH.~ No particular distinction between naval and military aviators. Total by end of June, 1913, to be about 225 certificated aviators of whom a fair percentage hold the superior brevet. In addition all the best civilian aviators are held at disposal. ~Military Aeroplanes.~ At the end of 1911 there were about 20 machines, mostly _Bleriots_ and _Farmans_. The majority of these are still in use for school purposes. At the end of March, 1913, the machines effective for war purposes were roughly as follows:-- _Bleriot._ } _Bristol_ (mono.) } _Caproni._ } _Deperdussin._ } Total _about_ 50, plus a number _Farman._ } of school machines. _Hanriot._ } _Nieuport._ } _Savary._ } About 40 machines were on order, including 12 _Bristol-Capronies_. ~Naval Aeroplanes.~ Effective at end of March, 1913. 1 _Calderara_. 1 _Guidoni-Farman_. 4 or 5 others. ~ITALIAN AVIATORS.~ Military.
