Available in PDF, EPUB and Kindle. Book excerpt: The US Army Aviation Test Board (USAAVNTBD) conducted the product-improvement test of the OH-6A Helicopter Winterization Kit to determine the suitability of the helicopter and winterization kit for arctic testing. The test was conducted in a simulated Arctic environment at the Climate Laboratory, Eglin Air Force Base, Florida. Testing included 30.5 hours' helicopter operating time and some firing of 7.62mm weapons. It was recommended that the design deficiencies be corrected, that further testing be accomplished in the actual arctic environment utilizing the 'Py-derichment' fuel control, that the validity of the MC's in long-duration mission performance evaluation with crew-area temperatures between 0 F. and 10 F. be investigated, that further testing of the effects of cold weather on the sliding Teflon bearing surface be conducted, and that suitable equipment be developed to permit a reliable aircraft starting capability down to -65 F.

Download or read book Product Improvement Test of OH 6A Helicopter Tail Rotor Balancing Equipment written by James P. Maguire and published by . This book was released on 1968 with total page 4 pages. Available in PDF, EPUB and Kindle. Book excerpt: Maintenance problems associated with high-frequency vibrations in the OH-6A were encountered in the reliability test program and in tactical use by field units. These vibrations frequently were attributed to improper balance of the tail-rotor assembly. Since this assembly could not be balanced using equipment presently in the Army inventory, the LOH Project Manager requested that the airframe manufacturer develop suitable balancing equipment. The tail-rotor balancing equipment consists of an accelerometer with mounting bracket, a vibration analyzer, a protractor, and electrical cables, which are contained in a fiberglass carrying case. These items are used in conjunction with the blade-tracking strobe light assembly. Power required for equipment operation is 24 volt's direct current which is obtained from the auxiliary fuel tank connector in the aircraft.

Nagata and published by . This book was released on 1968 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: An engineering flight test of the OH-6A helicopter equipped with the XM-27E1 armament subsystem was conducted at Edwards Air Force Base, California, by the US Army Aviation Test Activity. The objective of the test was to determine what effects the armament subsystem had on the performance and stability and control characteristics as compared with an aircraft without the armament subsystem. The testing consisted of 10.25 productive test hours and was conducted from 2 October 1967 through 24 October 1967. Performance degradation resulted from the drag imposed by the armament subsystem. The specific range at 2400 pounds gross weight decreased by 8 percent. The stability and control characteristics were essentially unchanged by the addition of the armament subsystem. During firing tests, there were no adverse control problems. However, during flight at 12 degrees left sideslip at 105 knots indicated airspeed (KIAS), the upper right windshield imploded. The sideslip angle should be limited to 8 degrees or less at 100 KIAS until the cause of the implosion can be determined. Noise level and vibration tests should be conducted during firing with the 'doors off' configuration. The performance data should be incorporated into the operator's manual. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Performance and stability and control tests were conducted on the OH-6A helicopter to determine compliance with the detail specification HTC-AD 369-Y-8003 and to provide information for the operator's manual. The testing was conducted at Edwards Air Force Base, California and at auxiliary test sites at Bakersfield and Bishop, California. The OH-6A met all performance guarantees except for the OGE Standard Day, 2613 pound gross weight, sea level hover guarantee. For this condition the hover height was 15 feet. The overall stability and control characteristics were considered satisfactory and complied with the requirements of military specification 8501-A with the allowed deviations in the detail specification with the exception of the maximum roll rate allowed in paragraph 3.3.15, which was exceeded but was satisfactory.

Download or read book Engineering Flight Test of the Production OH 6A Helicopter with Fairings Removed written by Marvin W. Buss and published by . This book was released on 1969 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flight tests were conducted to determine the effects on performance and flying qualities with various fairings removed from the OH-6A helicopter. The fairings removed were the lower anticollision light cover, the main rotor blade root end fairings, the main rotor center hub fairing and the landing gear strut fairings. Individually removing the lower anticollision light cover, the main rotor blade root end fairings and the main rotor center hub fairing did not significantly affect the performance of the helicopter; however, removing the landing gear strut fairings resulted in a definite decrease in performance. The performance in all fairings removed configuration was also significantly decreased. Stability and control tests were conducted in the all fairings removed configuration. Slight changes in control positions were evident but no major effects on flying qualities were observed. From a performance and flying qualities standpoint, it is feasible to operate the helicopter with these fairings removed. Although the performance changes are relatively small, allowances should be made in mission planning for all fairings removed and skid strut fairings removed configurations.
