The Pratt & 'W hitney Aircraft Di vision of United Aircraft Corporation concentrates on the manufacture of high.powered radial air-cooled engines. It was founded in 1925 as T he Pratt & Whitney Aircraft Company by a small group of aeronautica l engine exper te and has since become affiliated as a division of United Aircraft Corporation. The first engine developed in ita laboratories was the famou8 radial air.cooled '''Wasp,'' ori~inall y rated at 400 h.p. Later, its engineers d eveloped a larger engine of higher power, the "Bomet," and 8till later a smaller engine unit, t he ""'{asp·Junior." These three engines are aU or the nine ·cy linder Bingle ·row radial type. In 1929. Pratt & Whitney Aircraft began to experiment with t he t wo-row engine. In J 933 the Company announced the produ ction of a fourteen-cyHnder two-row engine to develop 700 h.p., t he "Twin W asp-Junior," and a 8lmilar engine o f 800 h .p., t he "Twin,WMP ." Success of the two-row models was immectia.te. They provide the power fo r many modern types of commercial and military n.ircrnft, including Buch outstanding examples as t he Martin Paci6c Clippers, Cur tiss P-30 Pursuit8, Consoli dated Na vy

Wit h t he two· row design completely accepted, new requirements for 0. high -output engine were met in 1937 by the production of t he 1,400 h.p. "Twin H ornet." To date, t he co mpony h68 produced more than 13,500 engines which have been winely used in military, commercial, and private aircraft ill a ll parts of the \Vorld. The company's p rt"Bent p roduction compr ises the two basic a ir-coolerl types-the single-row radial and ~he double-row radial. All models of both types are now available with the latest Pratt &0 ·W hitney desi!ln fea tures, and they cover a wide range of power adaptable for all types of service. They are equipped with completely automatic valve gear lubrication , as well as with patented Pratt & \Vhi tney automatic 'Power and mixture control. Th is latter feature, when used in conjun('tion with the R6Jnilton-St.onda.rd Constant Speed Airscrew, makes pOSSible a.ccurate control of cruising power and fuel consumption, with maximum performance, at any selec ted cnlising hf'ight. During the PMt year, Pratt & Whitney engineers have continued to concentrate on addition,,1 refinements in all models, with the resu lt t hat substantially.Jncrea.sed horscpowers have been made av ailable for take-otT and cruising opera tion. The cont.inued perfonnance record of Pratt &. Whitn~y aero-engines in all type8 of flying has justified the long periods of testa and expe rimentation which have p receded the adoption of all t he now standard Pratt & Whitney fea.tUl'Cfl, THE PRATT" WHI T NEY "WASP-.lUNIOR."

The ociote Zodiac hus developed for t he Air Ministry II mobile balloon, which co nsists essentially of a standa.rd Type B.D. kite-baUoon envelope nnd 0. detachable nacelle provided with au engine.

From that date up to the end of 1915 a ver y la rge num ber of airships was built, but with t he signing of the Treaty of Versailles, which restric ted tho size of Cerman airships to 30,000 cu b. m.

Two small passenger E\irships, conforming to the Treaty requirements and known 68 the " Bodensee" and "Nordste m," were built soon after the ,Var but these slups were confiscated under the reparations agreement ex isting at the time, the " Nordstern" being llllocated to France and the " BodcDSe(''' to

This ship, which WRS su bsequently named "C mf Zeppe lin, " was comp leted in 1928. The "C rnf Zeppe lin" made its first fli g ht on Sept. IS, 1928.

LARCE R JGlO AIRSHIPS :- Include large airships in t h e D epartment's p rogro.mme for ai rship development, but to defer auy d efinite p lallil pending t.ho clarification o f a ct ivities in the commercial a irship field , in which acti v itics the D epartment s hould co·operate w herever possible. EXPE lUM ENTAL :- Obt.l.I.in funtla and Legio immediately the construction of a me tal -hullcd airship of abou t 1,600,000 cub . fli. S in ce t.h e Joss of t.he " Macon," the Navy has only maintained one Airship Station, Lakehurst, in conunisaion. Sunnyvale, Co.!., w hich was s pecially buil t for rigid airships, was handed over to the Army . The non-rigids K . l , J .4 , which is about. ten yea.rs old , and 0. 1, w h ich was forme d y the Goodyear " Defender," and the l\Ie talellld Z,M.C.2 have been retained in com mission for trai.ning Ilnd experimental purposes. Two new no n -rig ids were ordered in 1937, in accordance wit.h thc progralllme mentioned above. In 1937, the Army .Air Corps abandoned the use of a irships. This d ecision was arrived at early in the year, and n o fina ncial p rovis ion \"as made for the ITIaintelHlnce of t he t h.ree Army non · rigid arships after July I, 193 7. Thef:!C ships have been deBated a n d the p ersOlUlcl dispersed . The airship s heds at. Scott Field, Ill., and Sunnyvale, Cal.. will probably be adapted for aircraft. use. The Air Corps con tinues to lise observation balloons for artillery a nd infa ntry co ·operation , In 1936, two motor balloons and a rnotor·bnll oon te nde!' wit.h colJapslble mooring. mast were o rdered.

GOOD YEA R -continued. THE GOODYEAR FLEET OF NON · RIGID AIRSHIPS. This fleet of non -rigid airships has bee n pr imarily developed for experimental Mld t raining purposes. It consists of five ships, all helium·inflated. Ill. their operation since 1925, t hese ships have a.massed 8 splendid record of performance, operating wit hout injury to a single passenger. Up to May 1, 1938, their record included 115, 176 ftighta, with 31 1,759 p B&Sengers carried, 3,096.010 miles fl own , and 69,409 hours in the air .

Founded: 1921. President: Carl B. Fritsche. Vice -Presiden t: Arthu r G. Sch losser. Secretary: George W . F ritsche. Treasurer: Earle 'W . Parcells . Manager: Edward J. Hill . The Company is the successor to the Aircraft Development Corporation , and continues to concen trate its efforts on the development of the metal.clad rigid type of airship, ,~ hi c h development has been continued in accordance with t he policy established seventeen years ago, when t he Company was organised to develop and build 8. small metal airship as an e xperimental uni t. The Z..M.C.2, the world's first successful metal·clad a irship, was the result of t he research and development eO,!Z8ged in since 1922. TWa airship wos comp leted in 1929 and delivered to the United States Navy in September of t,he same year, hav ing
'l"he shipa are 123,000 cu b. ft . in volume, contain t wo air bnllonet.a, are eac h powered with two 146 h .p . Warner
comp leted a ll contract requ irement£; to the complete satisfaction of the Naval authorities. Each trial was successful on t he first attempt. This airship has been in cootinuous operat ion s ince its delivery at Lakehurst No.vBI Air Station as an experimen tal Rod training ship, and has performed to the satisfaction of the personnel at that station. It is of interest to note that the metal envelope is still holding helium g88 as well as fonnerly f\.nd no serious deterioration of the " Alcl9.d" mate rial has been noticeable. The Z.M .C.2 has been fully described a nd illustrated in pre,~ious issues of this book. This ship was deflated for overhaul and iOBpection in 1935 a nd t he en velope was found to be in excellent condition . Up to t he ti me of deflation, the Z.M. C.2 bad made 468 flights, totall ing 1,232 hours. T he Company is continuing its experi mental a nd design work, concen trating on a type and size o f airship suitable for coast patrol, mine survey and submarine search, and eq uipped w ith a nacelle keel which. it is believed, will enable the s hip to alight on a ny protectcd harbour and moor to u il ollting buoy eq uipped with an adjustable stub mast.
