1ºTheir military men aren't gutless wonders like Biden and our military brass who let a Chinese surveillance Balloon cross the U S transmitting information as it did so--Hope U S citizen are aware they face a nuclear war leaving Biden President for life as he, our Congress, and top Brass and their families sit in well stocked and prepared Nuclear fallout shelters scattered across the U S, and contemplate how wise it was for Biden to give the Ukraine Oligarchs a promise of carte blanc support if they invaded Russian Crimea in their quest for a seaport ---almost a trillion dollars already and by the time they sit in the shelter ? ? all that in return for giving Hunter a multi million dollar know nuttin do nuttin position
2ºAJ Starling ,I think you don't know much about what your leaders are doing in Ukraine.Good day from Romania that will soon be pushed into Ukraine's position for your interests in eastern Europe.You should realize that there are people dying and that your interests are being realized with a lot of sange.Nu we like the Russians but we know very well that there is a fight between them and you and Ukrainians deliver the cannon fodder.Keep informed.Those of us in eastern Europe who are one step away from war because of the U.S. We don't digest easily What You're doing in Ukraine.
3ºMcIntyre Manix Morrison K first of all sowjet union wich includes 15 or more countries lost against afganistan. second one on one russia would not stand a week against usa in a conventional war. usa 300 milion people russia 144 milion. nato is not a part of the war imagine nato would send 1000 tanks to ukraine they will be in moscow in 10 days. selling weapons is not beeing a part of a war. at vietnam war russia sells all kinds of conventional weapons to the vietcong including mig 21 jets but they are not part of the war
4ºLinda Alcala-Harvey ...No. The entire region, Black Sea included, is an active war zone. It became a war zone when Ukraine used arm drones to sink a Russian ship & Russia retaliated by firing missiles from ships. Any military aircraft, manned or unmanned, is a legitimate target...since we are in an active proxy war with Russia. All this hand wringing & whining from a bunch of fake, triggered patriots on social media. It was an UNMANNED DRONE folks. No one but the Russian pilot was in any danger. I would expect our military to do the same thing if a Russian or Chinese drone encroached over the Gulf of Mexico. If they did not down a drone in that area...they would not be doing their jobs. The purpose of the military is to break things & that is the Russian pilot did. Our pilots would do the same.
5ºKg Kg that's due only to your ignornace and the degree and stupidity on your behalf.
Either do your search and know your subject or, shut the F**K up on it.
Aircraft Propeller Balancing
Propeller unbalance, which is a source of vibration in an aircraft, may be either static or dynamic. Propeller static imbalance occurs when the center of gravity (CG) of the propeller does not coincide with the axis of rotation. Dynamic unbalance results when the CG of similar propeller elements, such as blades or counterweights, does not follow in the same plane of rotation. Since the length of the propeller assembly along the engine crankshaft is short in comparison to its diameter, and since the blades are secured to the hub so they lie in the same plane perpendicular to the running axis, the dynamic unbalance resulting from improper mass distribution is negligible, provided the track tolerance requirements are met. Another type of propeller unbalance, aerodynamic unbalance, results when the thrust (or pull) of the blades is unequal. This type of unbalance can be largely eliminated by checking blade contour and blade angle setting.
