The present invention relates to a muffler (40) devised particularly for use with an engine of the type used on unmanned aerial vehicles (UAVs), and a UAV (10) having an engine (30) fitted with the muffler (40). The muffler (40) comprises a main body (51) having an interior chamber (60). The muffler main body (51) has a first end section (53) and a second end section (55). The first end section (51) is adapted for mounting onto the engine (31) by way of a first mount (81), with the interior chamber (60) in communication with an exhaust outlet of the engine (31) to receive exhaust flow therefrom. The second end section (53) is adapted to be mounted by way of a second mount (82) in a manner resisting movement with respect to the engine (31). In one arrangement, the second mount (82) is configured to yieldingly resist movement with respect to the engine (30). In another arrangement, the second mount (82) is configured to mount the second end section (55) under a preload resisting movement of the second end section with respect to the engine (30).
一种特别为用于无人驾驶飞行器(UAV)上使用的发动机而设计的消声器(40),以及一种具有装配有消声器(40)的发动机(30)的UAV(10)。消声器(40)包括具有内室(60)的主体(51)。消声器主体(51)具有第一端部(53)和第二端部(55)。第一端部(51)适于通过第一安装件(81)安装到发动机(31)上,使内室(60)与发动机(31)的排气出口连通以从其接收排气流。第二端部(53)适于通过第二安装件(82)以抵抗相对于发动机(31)的移动的方式安装。在一种布置中,第二安装件(82)配置成屈服地抵抗相对于发动机(30)的移动。在另一种布置中,第二安装件(82)配置成在抵抗第二端部相对于发动机(30)的移动的预载荷下安装第二端部(55)。
