В.Кондратьев Самолеты первой мировой войны

С IV являлся бомбардировщиком. Он отличался увеличенными размерами, крыльями с небольшой стреловидностью и двигателем Мерседес D.IV (220 л. с). Он мог брать до 70 кг авиабомб. Машины этого типа первыми совершили дневной бомбардировочный налет на Лондон. Было выпущено небольшое количество самолетов варианта СIV.

O.Thetford, P.Gray German Aircraft of the First World War (Putnam)

L.V.G. C IV
   This 1916 aircraft was a slightly enlarged edition of the C II designed round the straight-eight 220 h.p. Mercedes D IV engine. The reduction gearing enabled the engine to be almost completely buried, and a slow-revolving propeller of massive proportions was fitted. The introduction of a balanced rudder for the first time on an L.V.G. two-seater may be noted. An L.V.G. C IV made the first daylight aeroplane raid on London 28th November 1916. Engine, 220 h.p. Mercedes D IV. Span, 13.6 m. (44 ft. 7 1/2 in.). Length, 8.5 m. (27 ft. 10 3/4 in.). Height, 3.1 m. (10 ft. 2 1/8 in.). Area, 38.2 sq.m. (413 sq.ft.). Weights: Empty, 1,050 kg. (2,310 lb.). Loaded, 1,600 kg. (3,520 lb.). Armament, one Parabellum machine-gun.

Форум Breguet's Aircraft Challenge

The Luft-Verkehrs Gesellschaft (L.V.G) C.IV was a development of the most succesfull reconnaissance machine of L.V.G. - till then - the C.II. The C.II was actually built in the hundreds (in 1916 there were about 250 of them at the Front). The C.IV was built in small numbers.
   The C.IV was bigger and could be distinguished by its engine installation (alsmost or totally enclosed) and its really huge airscrew to move the air.
   If you size the airscrew with the personnel it may be about 4 or 4,5 meter in diameter ! It will probably be a slowly revolving screw, moving a lot of air.
   Other distinguishing parts are the unequal span wings, which seems actually to be a trademark of the early L.V.G. machines. Another point is the balanced rudder, which was a first time use of L.V.G. The typical 'split' in the aileron also shows on other pictures of this machine and is I think a trademark of the C.IV.
   Exceptional for this machine is the big exhaust (cowhorn model), which can be clearly seen. Think it was intended for night flying to suppress the exhaust flames, which would than give away the position of the machine.
   A little known feat is that on 28 November 1916 a lone L.V.G. C.IV dropped six 10 kg bombs in the neighbourhood of Victoria Station London. It was the first daylight raid on London from the Germans.

SOME 1917 TYPE GERMAN AEROPLANES.

The L.V.G. (Type C. IV).

   Differs very little from the L.V.G.'s already dealt with in the columns of "FLIGHT." It is of slightly larger overall dimensions, and has an 8-cyl. vertical Mercedes engine. The armament consists of two machine guns mounted as usual and of four bombs.
