Minimum Effort Required to Pilot Bell's HU-1 Iroquois

Fort Worth, Tex.—Designed from scratch as a turbine-powered utility helicopter for the U. S. Army, with components capable of minimum 1,000 hr. of operation between overhauls, Bell Helicopter’s all-new HU-1 Iroquois is a highly stable rotorcraft that requires a minimum of pilot effort.

AW 650 Freighter Nears First Flight

London—Armstrong Whitworth AW 650 Argosy, twin-boom, turboproppowered freighter and coach transport is scheduled to make its first flight this month as the initial aircraft in a family based on the packet fuselage principle. Two other prototypes, now under construction, are the AW 660, a pressurized military transport which can be fitted with alternative tail doors (AW Feb. 11, 1957, p. 41), and the AW 670 Airbus, a short-haul configuration which has a wider fuselage and can be used for passengers, freight or ferry missions.

LETTERS

At the National Symposium on Extended Range and Space Communications, I presented a paper on “Optimum Frequencies for Space Vehicle Communication.” I received letters and long distance calls from interested readers of your publication referring to p. 88 of the Oct. 20 issue (reporting on the symposium) about an obvious misquotation . . . (Discussing radar echoes from the aurorae, the article reported, “Echoes were also detected at 800 mc., with Doppler shifts as great as several hundred megacycles”).

Critical Airway Gaps Remain in Far East

Bangkok—Despite rapid development of air navigation facilities throughout the Far and Middle East during the past two years, dead reckoning is still a navigational rule of thumb on many routes in these two areas. Critical gaps in the projected chain of airways facilities are being filled as rapidly as the present Civil Aeronautics Administration’s technical assistance program permits.

First ARPA Satellite Launches To Seek Key to Improved Vehicle

New York—Advanced Research Projects Agency plans to launch several satellites during the forthcoming months for the sole purpose of learning how to build better satellites, according to ARPA’s chief scientist, Dr. Herbert F. York. Before it becomes possible to build something as complex as a reconnaissance satellite or a communications satellite, it will be necessary to develop vehicles much more advanced than the "spinning cans” lofted into the air by the first Explorers.

N. Y. Airways Studies Turbine Conversion

New York—New York Airways has its eye on several new helicopters now in the development stage, but a likely first move would be conversion of its present fleet from piston to turbine power, according to President Robert L. Cummings, Jr. Next round of equipment for the helicopter airline, which recently shifted from Sikorsky S-55s and S-58s to Vertol 44Bs, will come in 1960 if the company decides its best bet is “turbinized” Vertols.
