Dornier Sets Hot-cycle Helicopter Tests

Immenstaad, W. Germany—Relatively low purchase price of the Dornier Do. 132 light turbine helicopter and low maintanance requirements resulting from the hotcycle aircraft’s reaction rotor system are said to offset the somewhat higher fuel consumption inherent in the system's lower efficiency.

Major Role in Electronic Air War Earned By Radar Chaff

Los Angeles—American aircraft are increasing the use of chaff, one of the oldest techniques for confusing enemy radar defenses, as part of the quickening pace of electronic warfare over North Vietnam. The practice of confusing enemy radar operators and masking the presence of bombers by dispensing from attacking aircraft large quantities of metal foil, or chaff, cut to lengths resonant at the defense radar frequency to return spurious radar returns, dates back to the now famous Royal Air Force raid on Hamburg in 1943.

Air Reserve Activation Strains Resources

Any future reserve call-up of the Air Force, National Guard or Navy air units will cut deeply into this nation’s reserve capability. Within the Pentagon, such a call-up is expected in view of the tightening manpower requirements of the war in Southeast Asia—South Vietnam, Laos and elsewhere.
