FLEXIBLE SUSPENSIONS FOR TURBOPROP AND TURBOJET POWER PLANTS 550183
The turbine power plant has inherent vibratory disturbances. It is also a fragile device. A flexible suspension holding the power plant in the airframe must protect one from the other. To do this, the suspension must control natural frequencies to limit vibration transmission, hold the power plant in the airframe through ultimate load conditions, distribute loads into a desirable pattern, maintain stability, provide adequate service life, and permit simple installation removal without size, weight, and complexity disadvantage to the installation.
There are many power plant, airframe, and general installation factors which contribute to these characteristics. The use of these factors and their effect, as well as a tabulation of required data are presented.
