23* FLIGHT AUGUST 26TH, 1943 Sixty-third of the Latest Recognition Series Aircraft Types an KAWANISHI T.97 HP11 \HIS is considerably the larger of the JapaneseNavy's two four-engined flying boats, and is a development of the Kawasaki flying boat put into service on the Yokohama-Saipan service, this in its turn being developed from the Sikorsky S-42-B. Primarily intended for sea reconnaissance duties, the Kawanishi T.97 has frequently been used during the present war for bombing, and it can also be used as a torpedo-bomber. It is powered by four Kinsei 14-cylinder, dcuble-row air-cooled radial engines which are rated at 900 h.p. at 13,000ft., at which altitude the Jap aircraft has a top speed of 215 m.p.h. and a cruising speed of 165 m.p.h. Its service ceiling is 26,000ft. and its maxi- mum range about 1,500 miles, or approximately nine hours. Normal tankage accommodates 1,500 gallons of fuel, but it has an estimated maximum tankage of 1,950 gallons. Its normal flying weight is 45,000 lb., and it carries a crew of ten men. A maximum bomb load of 3,500 lb. can be carried at the expense of reducing the cruising range to 1,450 miles. Armament of the earlier versions of the T.97 comprised either 7.7 mm. machine guns or a 20 mm. cannon in the nose, and 7.7 mm. machine guns in a dorsal turret aft of the wing. Later versions, however, have swapped the dorsal turret for a tail turret. From a head-on view the T.97 nas a wide, thin wing, strut-braced to the side of the hull just above the first step, and a slight dihedral from the point of its attachment to the inverted "V" centre -section struts. In plan the centre-section of the wing is seen to extend with parallel edges to the point of attachment of the pairs of parallel main struts, which is almost to the stabilising floats. The comparatively short outer panels taper moderately on their trailing-edges and very slightly on their leading-edge^, the tips being rounded. The small tailplane has P^ edges and rounded tips, and is braced by parallel -•HIGH STRUT-BRACED fAILPLANE AND CUN TURRET MODERATE TAPER, SUCHT TAPER WIDE RECTANGULAR CENTRE SECTION STEPS ENCINES CENTRED ON PARASOL WINC HXED WINC ROATS BRACEDWING STRUTS TAPERED SLAP-SIDED HULI PARALLEL EDGES Span Length Height Wing area. .
