Openings for Young Business MenTHE Air Ministry announces that 15 to 211 vacancies for permanent commissions in the Stores Branch of the Royal Air Force will be offeredfor competition among young men between 23 and 25 years of age, who have had not less than five years' business experience in a firm of standing.This is the second competition under the scheme initiated last year to obtain men with a business training to control and administer the supply of thehighly valuable and complex equipment of the Royal Air Force. From among applicants a limited number will be selected to sit for anexamination in the light of the information furnished by them and by gentle- men whom they will be asked to name as referees. The examination willbe held in London and Will consist of two parts, an interview before a board and a written examination in English, general knowledge and arithmetic.The written examination will be of such a character that men of good general education can take it without special study. Accepted candidates will be gazetted to commissions as Pilot Officers onprobation and will receive six months' training in their future duties. After a year's satisfactory service, they will be eligible for confirmation in theirappointments and for promotion to the rank of Flying Officer. Promotion above the rank of Flying Officer will be by selection. . The pay of a Pilot Officer in the Stores Branch is 12 s. 'Id. a day, and, includ-mg the value of allowances which may be provided in kind or in cash, the lpta] emoluments amount at present to approximately £365 a year. The similar figure for Flying Officers on promotion will be £401, and for Group'-aptains (the highest rank for which provision is made) £1,140. The ex- penses in Royal Air Force messes are strictly regulated, so that officers even<'f the most junior rank can live on their pay. Rates of pay are subject to variation in accordance with the cost of living. The appointments arepensionable. Enquiries for copies of the regulations and for application forms should be made in writing to the Secretary, Air Ministry, London, W.C.2.Completed application forms should reach the Air Ministry not later than May 23. Institution of Aeronautical EngineersAT the General Meetingof the Institution, held on March 29, the following resolution, regarding the amalgamation with the Royal Aeronautical Society,was unanimously passed :— That this institution being of opinion that it is desirable in the best interestsof the British aeronautical profession that this Institution should amalgamate with the Royal Aeronautical Society, Hereby Resolves to amalgamate withthe Royal Aeronautical Society upon the terms agreed between the Council and the Council of the Royal Aeronautical Society, and dated 27th January,1927. And this Institution authorises the Council of the Institution to do all thingsnecessary for the purpose of carrying the agreed terms into effect. Torsional VibrationAT a meeting of the Junior Institution of Engineers, held on March 18, Mr. J. Calderwood, M.Sc, read a paperentitled " An Investigation of TorsionalVibration with particular reference to Aircraft Engines." Mr. Calderwood said that there was available a vast amount of publishedinformation on the general subject of vibration, but on examination it would be found that very little work, mathematical or experimental, had been doneon the particular problems which had to be considered by the designer of a machine liable to suffer from critical periodic torsional vibration of its shafting.In many cases, where trouble had been experienced due to torsional vibration, damping devices had been used. While a machine might, with heavy damping,run at a critical speed without fracture of the shaft, it was not under those conditions running economically, for a large amount of power was absorbedin damping the vibration. The alternative was to arrange the shafting of an engine in such a manner that the critical speeds were all either above orbelow any speed at which the machine might be required to operate continu ously in service. In an appendix to his paper, Mr. Calderwood gave some formula? for thecalculation of the natural frequency of vibration of various arrangements of shafting such as occurred in aeroplane and airship engines. The paper concluded with a brief note on the measurement of torsionalvibrations. 211
