292 FLIGHT I // // j • from left to right, these three Hussion ! drawings show the nosewheel assembly, the / main-undercarriage assembly and the retractable tail bumper AntOIlOV An-10 (continned from page 289) . . . spars, are of the high-strength light alloy B-95 [V-95], while allother structure members are of an Al-Cu-Mg alloy. The wing is divided into the centre section, two intermediate sections andtwo tip sections. The centre section is of two-spar stressed-skin construction, and the intermediate sections have two spars con-nected to form a stiff box structure, the rear pan housing the double-slotted Fowler-type flaps. The maximum flap deflectionof 41 deg gives an increase of ACL=1.0 in lift coefficient, thuscontributing to the low landing speed. The tip sections are similar to the intermediate sections. Wing profile "varies throughout thespan, thus giving effective aerodynamic twist." The landing gear consists of the nosewheels and mainwheelsand a tail-skid. The nose-gear unit has twin wheels (without brakes). The wheels have a common axle, suspended on anoleo-pneumatic leg and having a stroke of 420 mm. The nose- wheel may be turned 35 deg to the left or to the right. Wheelsteering control is hydraulic, and the leg has a built-in hydraulic damper. The main landing-gear units have four braked wheels, built intoone bogie unit; tyre size is 1,050 X 300 mm. Hydraulic disc brakes are used. The oleo legs "again use nitrogen instead of air" andhave an effective stroke of 340 mm. A tail-skid serves to protect the rear section of the fuselage "if the aircraft attitude exceeds the prescribed limit angle." The gear can be lowered in 10 to 12 sec.The Russian description concludes: "The hydraulic system serves for actuating the landing gear and the flaps. Hydraulicpower is also provided for nosewheel steering, for braking, window cleaning and for supplying certain instruments, among them theautopilot. Rated fluid pressure equals 150 kg/sq cm [2,140 lb/sq in]. The hydraulic system consists of two parallel-connected.independent units, each fed from two hydraulic pumps driven by the engines on the respective side of the aircraft. An auxiliarysystem may be actuated by a hand pump. Stainless steel tubing has been used throughout. "The rudder is supported in three bearings, the lowest of whichis a thrust bearing. Both halves of the elevator are supported in four bearings each. All tail surfaces are built up from extrudedaluminium-alloy profiles and from sheet. Rudder aerodynamic compensation amounts to 32 per cent chord; elevator and aileroncompensation attains 29 per cent. Trimmers are electrically actuated but have an emergency manual control. A spring servo-compensator has been used on the rudder, relieving the pedals from excessive forces due to aerodynamic over-compensation. Allcontrol surfaces are mass-balanced units. "The control system contains no boosters; all movable surfacesare actuated by pushrods." NORTHROP NATO PROJECT A DESIGN by Northrop, the N-156F, has been approved bythe U.S. Government as a low-cost but high-performance fighter for use by America's smaller NATO allies. The aircraft,which is twin-engined (J85s with afterburners) and has been projected by the Northrop Corporation in parallel with theU.S.A.F. T-38 programme, will go into production soon and a first batch is expected to be available—presumably for sale—in the1961-65 period. The N-156F project was briefly described in Flight for June 20, 1958. JOHN DE HAVILLAND AWARD WHEN John de Havilland was killed on a test flight in 1943a trust fund was set up in his memory by Sir Geoffrey and Lady de Havilland. Since 1945 this has been administered by theSociety of British Aircraft Constructors, and until recently was used to assist boys wishing to take up apprenticeships in theindustry but unable to do so without additional financial help. But over the last few years, economic conditions of training in theindustry have changed, and for some time there have been no requests for help from the fund. It is therefore being used for a new form of award, to developpowers of leadership by experience in any form which may help to widen a man's outlook, and is again to be administered by theS.B.A.C. The value of the award is £400; only one is tenable in any year; and candidates are invited to make their own proposalsfor the use of the money, such as for travel, academic training (at home or overseas), or technical, commercial or other experience(again either at home or overseas). The experience gained should be of benefit to a man working in the aircraft industry, thoughthis may be widely interpreted. Candidates should be between 18 and 25 years of age in the yearof the award and will be judged on their record, merits and character and on the originality and resource of their proposedscheme and efficiency in presenting it, both in writing and also at an interview. Each holder will be required to make a monthlyreport on progress and (at the end of his period) a full report on what he has done and the experience gained. The first tenuremust not stan before August or September this year, and applica- tions should be sent in not later than May 15 to the Society ofBritish Aircraft Constructors Ltd., 29 King Street, St. James's. London, S.W.I. FERRANTI A.T.C. SYSTEM? "pROM a recent personnel advertisement in The Observer•*• it appears that the computer department of Ferranti Ltd. is preparing to enter the field of air traffic control. They call forlogical designers, programmers and engineers for air traffic con- trol and radar data-handling systems and also for electron!. andmechanical engineers to work on high-density magnetic recording! analogue-to-digital conversion and other techniques for data-transmission systems. The Ferranti computer department, >.vhK* is based at Bracknell, Berks, was not willing to amplif' "^sinformation.
