Spotter's Quiz No 7
Twin-Engine, Single-Tail Bombers

[missing]

50 Bristol Beaufort

Developed from early Blenheim designs, the Beaufort is now serving in its second combat version; actually bears closer resemblance in size to the Beaufighter than to the Blenheim. Powered by two Bristol radial engines, each developing, 1,065 hp, it has top speed of about 310 mph. It has wing span of 58', is 44' 2" long, and measures 14' 3" in overall height. Use as torpedo plane indicates long range.

Wing is mid cantilever type with marked dihedral on outboard panels, equal sweep-back and taper.

Engines have radial cowlings completely under- slung, extend forward to cockpit line.

Fuselage has slab sides, high conservatory in fore section, rounded turret aft of trailing edge.

Tail is monoplane type, semi-wasp design. Tail~ plane, parallel with fuselage top-line, is tapered.

Stepdown Aft of Wing

51 Douglas Boston

Developed from the highly successful A-20 designs and used by the British and American as a light bomber and night fighter, this is the finest plane of its type to serve widely in the desert. Powered by two 1,300-hp Wright radial engines, it has top speed of more than 300 mph. It has a wing span of 61' 4", is 47' long, measures 16' in overall height. Actual figures on armament and performance are restricted.

Wing is high cantilever type with slight dihedral, straight leading edge, tapered trailing edge.

Engines have radial cowlings, underslung nacelles taper aft of trailing edge.

Fuselage is streamlined to pronounced step-up aft of wing trailing edge, extremely long nose.

Tail is monoplane type with high triangular fin and rudder, dihedral on swept-back tailplane.

Dihedral Tailplane

52 Junkers Ju-88

Although powered by liquid-cooled engines, the Junkers Ju-88 actually resembles radial powered planes because of circular radiators. Powered by two Junkers Jumo 1,200-hp engines, it has top speed of 321 mph, carries a bomb load of 2,200 pounds. Resembling the Bristol Beaufort in outline and size, it has wing span of 59', is 46' 6" long, measures 15' in overall height. It has off-center bombing post.

Wing is low cantilever type, straight center section, irregular taper and sweep-back outboard.

Engines have circular radiators, long nacelles extending far forward and back to trailing edge.

Fuselage has snub-nose, compact conservatory fully forward of wing, off-center bombing post.

Tail is monoplane type, full wasp design, equal taper and sweep-back on tailplane set far forward.

Bombing Post, Conservatory

53 Martin Martian

Known to most readers as the Marauder, the B-26 has recently changed its name. But whatever the name, it remains the hottest medium bomber in service — with ability to fly faster, farther, with greater load than any similar Axis plane. Powered by two Pratt & Whitney radials rated at 1,850 hp, it has speed of over 350 mph, lands at only 112 mph. It has wing span of 65', is 58' 3" long.

Wing is high cantilever type set far back on fuselage, equal sweep-back and taper, round tips.

Engines have radial cowlings which taper to point aft of trailing edge, extend far forward.

Fuselage is almost round, cigar-shaped, gun em- placement aft of tail, turret on top.

Tail is monoplane type, high triangular fin and rudder, equal sweep-back, taper on high tailplane.

Small Wing, Round Fuselage

54 Vickers Wellington

With six versions so far used in three years of war, the Vickers Wellington stands as a long-lived veteran of combat. Powered by two Bristol radial engines developing total of 2,750 hp, it has speed of 280 mph and ceiling of 24,000 feet. It has a wing span of 86'' 2", is 64' 7" long, measures 17' in overall height, has bomb load exceeding 4,000 pounds. Some Wellingtons have liquid-cooled engines.

Wing is cantilever midwing type set far back, equal sweep-back and taper, elliptical tips.

Engines have radial cowlings and are inset into wing, tapering back to ailerons.

Fuselage has perfectly straight top line, nose to tail, slab sides, long nose and tail gun turret.

Tail is monoplane type, narrow triangular fin, straight rudder, swept-back tailplane far forward.

High, Narrow Tail

55 Martin Baltimore

Developed from the excellent Maryland design, the Martin Baltimore is designated A-30 by the US Army Air Forces, and ranks as one of the highest-climbing, fastest-flying medium bombers in service. Powered by two Wright radials, each developing 1,600 hp, it has estimated top speed of 320 mph. It has 61' 4" wing span, is 48' 6" long, and measures 17' 9" in overall height.

Wing is cantilever mid type with marked sweep- back, slight taper, elliptical tips, no dihedral.

Engines have radial cowlings, tubular nacelles terminating in blunt tip at trailing edge.

Fuselage is narrow, deep-bellied, with step-down from conservatory, step-up on bottom aft of wing.

Tail is very high, with sloping dorsal fin, elliptical rudder, equal tailplane taper and sweep-back.

Tubular Nacelles

56 Martin Maryland

Work horse of the Martin bomber family during the early months of lend-lease operation, the relatively low-powered Maryland has excellent flying characteristics. Powered by two Pratt & Whitney radial engines, each developing 1,050 hp, it has speed of 304 mph, ceiling 29,500 feet. It has wing span of 61' 4", is 46' 8" long, measures 10' 1" in height. Like the Baltimore, it has marked step-up aft of wing.

Wing is mid cantilever type with equal taper and sweep-back, elliptical tips, no dihedral.

Engines have radial cowlings, tapered nacelles terminating in point at trailing edge.

Fuselage is narrow, deep-bellied, with straight top line broken by transparent turret aft of wing.

Tail is monoplane type with triangular fin, elliptical rudder; tailplane has taper, sweep-back.
