Petrie and published by . This book was released on 1967 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presented are the results of engineering flight test of the UH-1C (UH-1B/540 rotor) helicopter equipped with the M-5 grenade launcher and the XM-158 or XM-159 airborne rocket launcher pods suspended from the X-156 multiarmament helicopter mount. Tests included 32 jettison flights for the XM-158 pods, 20 jettison flights for the XM-159 pods and 16 firings of the XM-159 pods. The objective was to determine quantitative effect of the XM-159 pods installed from the XM-156 mount on the stability, control and performance of the helicopter; to determine the XM-158 and XM-159 jettison characteristics and define the flight envelope for safe jettison of the pods; and to determine the flight envelope for firing the XM-159 pods. There were no significant adverse changes in the stability and control characteristics of the UH-1B/540 due to the installation of the XM-159. Previously reported longitudinal dynamic instability in climbs was also present throughout the tests. Self-excited undamped lateral 2/3-per-rev vibration was prevalent during the tests. Insufficient rocket-to-aircraft clearance for firing the XM-159 on the XM-156 mount was present without the addition of 4-inch cast aluminum spacers between the XM-156 mount and the universal pylon. The XM-159 was adjusted to maximum elevation to provide sufficient clearance for firing with the spacers installed. No major stability and control problems were encountered during the firing tests of the XM-159 or during the jettison tests of both the XM-158 and XM-159. Recommended flight envelopes were developed for jettison of both systems. (Author).

Download or read book Engineering Flight Test of Uh-1b Helicopter Equipped with Xm-47 Antipersonnel Mine Dispensing Subsystem written by Manfred Reif and published by . This book was released on 1966 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: A limited engineering flight test was conducted to provide sufficient engineering data for a safety-of-flight release for the UH-1B helicopter equipped with the XM-47 antipersonnel mine dispensing subsystem. An additional objective was to provide sufficient performance and stability and control data to update the operator's manual data to be used for UH-1B helicopters equipped with the XM-47 subsystem. Testing consisted of 42 productive flight hours. When the XM-47 mine dispensing subsystem was installed on the UH-1B helicopter, antipersonnel mines could be safely dispersed within the recommended flight envelopes. In cases of emergency the dispensers could be safely jettisoned within the recommended envelopes. Jettisons during entry into autorotation and in close proximity to the ground should be avoided. The flying qualities of the UH-1B were essentially unaffected by the installation of the XM-47 mine dispensing subsystem.

This book was released on 1970 with total page 427 pages. Available in PDF, EPUB and Kindle. Book excerpt: The AH-1G helicopter manufactured by Bell Helicopter Company (BHC) was designed specifically to meet the US Army requirements for an armed helicopter. Tandem seating is provided for a two-man crew. The main rotor system is a two-bladed, semi-rigid, 'door hinge' type with the stabilizer bar removed. The engine is derated to 1100 shp due to the maximum torque limit of the main transmission. Distinctive features of the AH-1G are: the narrow fuselage (36 inches), the stub midwing with four external store stations, the integral chin turret. The flight control system is of the mechanical, hydraulically boosted, irreversible type with conventional helicopter controls in the aft cockpit (pilot station). The controls in the forward cockpit (copilot/gunner station) consist of conventional antitorque pedals and sidearm collective and cyclic controls. An electrically operated force trim system is connected to the cyclic and directional controls to induce artificial feel and to provide positive control centering.

This book was released on 1970 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: Within the scope of this test, the AH-1G helicopter is suitable for the armed helicopter mission provided the insufficient directional control power and inadequate tail rotor drive system torque limitations are corrected. A directional control margin of 10 percent while hovering is the minimum acceptable for normal operation. Installation of the engine inlet screens and the engine particle separator decrease the performance capability of the AH-1G when maximum power available is the limiting parameter. The level-flight performance capabilities of the AH-1G vary with longitudinal cg location and improve as the cg moves aft. The degradation of hover performance capability when hovering in adverse crosswind is significant. The excellent climb performance, particularly from SL to 10,000 feet, enhances the capability of the AH-1G for the attack helicopter mission.

This book was released on 1967 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Army Preliminary Evaluation of the UH-1C/XM-30 weapon system was conducted by the U.S. Army Aviation Test Activity at Edwards Air Force Base and Fort Irwin, California. The degradation in level flight performance attributed to the weapon installation was defined and no objectionable flying qualities were encountered during firing or non-firing tests. The armed mission capability of the helicopter was degraded by high levels of stress, vibration, blast, and noise during firing and restrictive limitations were imposed by gun malfunctions and system gross weight. The reliability of the weapon system was poor and should be improved prior to further Army testing.
