APRIL 24, 1919 Fig. 9 shows the framework construction at the rear of the fuselage. 5. Undercarriage p~ This component was not salved, and in the scale drawings the D III undercarriage has been supplied, as the two are conjectured to be substantially similar. Fron the sockets on the fuselage, it is clear that the limbs of the undercarriage vee finished in ball joints. The following particulars regarding the undercarriage are taken from a French source. It is of the same type as that shown in dotted lines in the scale drawings, but the centre line of the axle is vertically underneatli the leading edge of the lower planes, and 31J in. below this leading edge at the centre section. The track is given as 61 in. in the French drawings. Engine and Mounting The engine, a 180 h.p. Mercedes (reported to be No. 42932, B.N. 827, M.N. 63, guaranteed till 30/1/19), is carried on rectangular-section ash bearers (^i'a *n- by i£ in.), which are lightened in places to I section. At the front end the bearers project a few inches beyond the U-shaped front bulkhead. Two other similarly-shaped bulkheads support the bearers in the places shown by dotted iines in the side view o1 the scale drawings, and at the rear the bearers are mortised into the behind-engine bulkhead, so that the end of the bearers are flush with the rear surface of the bulkhead. The top ol the bearers is covered on either side with a 3-ply shell which extends to the side of the fuselage. In the three- quarter front view photograph may be seen an aluminium scoop (there is also one on the starboard side), which leads air round the crankcase for cooling purposes. The air escapes by holes which are visible just above the leading edge of the lower plane. Radiator The radiator no longer occupies the position it had^on the D III model—i.e., in the centre section—but now closely follows Fokker practice. Fig. 11 shows the shape and con struction, and it will be noticed that the whole radiator is ^tuated above the crankshaft. The tank at the head ot the radiator is of sheet brass, covered with an aluminium lacquer. ^J L.H&_L The construction, it will be observed, ls^very simple. " A large number of oval-section tubes of thin^brass (9 mm. by 4 mm. cross section), are arranged vertically between the /*?-., Some constructional details of D XII Pfalz.—1. Attachment of bottom wing spar to body. 2. Top plane section compared with R.A.F. 14. 3. Spars and ribs. 4. Reinforcement of wing spars at point of attachment of struts. 5. Strong support of false spar, to which aileron is hinged. 6. Spar fitting. 7. Diagrams of struts. 8. Tubular support for pilot's seat. 531 II
