25 January 1952 107 Principal features of the "modern Montgolfier" outlined in the letter from Mr. B. van der Klaauw. A = Turboprop (one of four). B~Duct conveying hot air to interior. C = Centra I hot-air distribu tion duct. D = Burners (16inall). E = Fuef tank for burners. F= Fuel lines. G —Air pocket (eight in all). SECTION a-a The inventor has calculated the dimensions of the air pocket to be 820ft by 147ft diam, and goes on to give the following weights : lb Construction of ship 176,360 Passengers (100) 17,63 Crew (50) 8,80 Turboprop fuel 147,700 Burner fuel 66,00 Miscellaneous , .. 24,250 Total weight 440,7401b Dealing with the lift expected, the inventor calculates a gross lift of 529,100 lb when the air is heated to 288 deg, giving a pure lift, at sea level, of 88,000 lb. This would result in a ceiling of some 2000 m, or 6,500ft. The ideal ceiling, however, is 16,400ft, which demands an air-pocket temperature of 495 deg. The inventor has calculated a loss of heat at that altitude of 7,577.6 calories per second, and says 5,950 lb of diejsel oil per hour will be necessary to compensate for this loss; the exhaust gases from the four turboprops are estimated to supply 5,752 calories per second and can thus compensate two-thirds of the loss. If a better kind of impregnated fabric were used for the envelope the loss might be much reduced. The airship has two horizontal surfaces, situated at one-third and two-thirds of its length for stabilizing and control purposes. Their angles of attack may be altered independently, or together, for producing alterations in the ship's height or trim. The inventor prefers turboprops, since at the calculated cruis ing speed of 250 m.p.h. the fuel consumption of a pure jet is about four times that of a turboprop. A maximum range of about 6,000 miles has been calculated, and an endurance of 26 hours might be possible. Mr. Favejee believes a prototype of such a ship can be built, and he is anxious to hear comments from readers. Wassenaar, Holland. B. VAN DER KLAAUW. FORTHCOMING EVENTS This week we give a full list of events so far notified. Also included are the Royal Aeronautical Society's branch fixtures for the current session, normally, it is impracticable to fist these events, 01 there are now so many branches, all of which arrange numerous lectures and other functions. The extent of the list, and the calibre of many of the lecturers, bears witness to the healthy state of the Society's provincial offshoots. Jan. Jan. Jan. Jan. Feb. Feb. Feb.
