MAY 26, 1927 BRISTOL "JUPITERS"IN CZECHOSLOVAKIA: This successful air-cooled radial engine has found favour in several foreign countries, and our illustrations show the "Jupiter " installed in three Czecho-Slovakian machines Left, the AviaB.H.21 single-seater fighter; centre, the Avia B.H. 33 high-altitude single-seater fighter (Series VI engine) ; and, right, the Avia B.H. 26 two-seater fighter. IN PARLIAMENT Airships REAR-ADMIRAL BEAMISH, on May 17, asked the Secretary of State forAir whether the R100 can be rehoused at Howden without first being trimmed and ballasted at a mooring mast at that station : and what is the estimatedcost of a mooring mast ? Sir Samuel Hoare : There is some misapprehension ; the trim of an airshipriding at a mast is different from that required for her housing in a shed, and consequently she has to be retrimmed for this purpose after she has leftthe mast. The cost of a mooring tower is approximately £51,000, if similar to that erected at Cardington. or £44,000 if certain features are omitted. Rear-Admiral Beamish asked what arrangements were proposed forrehousing the R100 if no mooring mast is available at Howden. since Rim will be in the Cardington shed ; and can RlHl, when completed, be housedat Howden ? Sir S. Hoare : It is proposed to construct a second shed at Cardington.and this shed will be available for rehousing R100 during her trial;, which will be carried out from the Cardington mast. The height of R101 will not permitof her being housed at Howden. The cost of the new shed (included in the Estimate for this year) is some-thing over £100,000. Cairo-Karachi Air Route and Persia LIEUT.-COMDR. KENWORTHY, on May 18, asked the Secretary of State forForeign Affairs whether permission is still being refused to British aeroplanes to fly over Persian territory on the Cairo-Karachi air route ; if. so, what stepsare being taken to remove the difficulties ; and if he will state the reasons put forward by the Persian Government for the prohibition ? Mr. Locker-Lampson : No reason has been given by the Persian Governmentfor their recent decision not to open a route along the southern coast of Persia to international air traffic. They have, however, stated that, shouldthe Persian Parliament eventually approve the International Air Convention of 1919, to which the Persian Government acceded in 1920, they will beprepared to fix another line for international traffic, but that, in that event, the internal situation and frontier considerations will lead them to choose alineacross Central Persia. I have no further statement to make regarding the present negotiations on the subject with the Persian Government. Airships MR. VIAVT asked the Secretary of State for Air (1) if he can give thefactor of safety aimed at in the new airships, in view of the fact that two experts are now examining the designs and factors of safety of the two airship* •and have the constructors of the R 100 been apprised of this examination', with a view to delaying the construction until the experts' Report is issued -(2) if he is satisfied that the strength of the airship R 100 has, in fact, been doubled ; when the change in design took place and was it notified to, andconfirmed by, the Air Ministry or any other authoritative panel or committee ; and, as the design of this airship is settled and the ship is now underconstruction, can he state the increase of weight in the structure of the ship consequent upon the reported increase in the strength ? Sir S. Hoare : R 100 (as also the Government airship R 101) has to conformto the general principles of airworthiness (including certain factors of safety) which were laid down in October, 1924, by the Airworthiness of AirshipsPanel of the Aeronautical Research Committee, whose Report is on sale as No. 970 of the series of Reports and Memoranda issued by that CommitteeThe two distinguished scientists, to whom I referred in my reply on Mav 4 were appointed to examine the actual designs of both airships and determinetheir airworthiness in accordance with the Panel's Report The Airship Guarantee Company were informed in July, 1926, of the appointment of thesegentlemen as the Airworthiness Authority for the two airships, and have since been in direct communication with them. I am aware that the AirshipGuarantee Company have considered the question of embodying additional factors of safety and their suggestions have been communicated to the Air-worthiness Authority, but I do not think I can properly make any more detailed statement on the strength of R 100 at the present time, when theAuthority's examination of the design is still in progress PUBLICATIONS RECEIVED Eagle VIII and Falcon III Aero Engines.
