    Correct but this first UDF (Un Ducted Fan ) tech by NASA and GE was put on the backburner in the 80's. The prove of concept worked, but at that time do the higher noiselevel, extreme high production costs and low fuel costs made the UDF financial uneconomical and political unwanted. Due to modern composites, new tech and high fuelcosts GE, P&W and Safran/CFM work togheter for the the 2nd generation UDF. The 2nd gen UDF makes now less noise then a "regular' ducted fan due to the fact that one set of blades is stationary instead of counter rotating in the original UDF. This Makes this low fuelburn/noise engine a sustainable option for "regional" jets. Point to point travel did explode so the demand for economic to operate "regional" jets has drastic increased. The term regional has been watered down today. The baby Airbus the A318's with luxury seatings is operated by British Airways as an intercontinental aircraft on the London to New York route!. Smaller aircraft more departures in a day. And budget/holidaycharter airlines use f.e 737's in cattletruck seat configuration for the low and medium routes.

    @@cgirl111 Depends on what regulation you're talking about. For propellors, look at 14 CFR Part 25.905(d) Design precautions must be taken to minimize the hazards to the airplane in the event of a propellor blade fails or is released by a hub failure. Hazards that must be contained include damage to structure or vital systems due to failed blade and the unbalance created by such failure. For turbofans, 14 CFR Part 25.903(d)(1) Design precautions must be taken to minimize hazards to the airplane in the event of rotor failure or fire within the engine which burns through the case. Interestingly enough, as stated in FAA AC 25.905-1 Section 5.a. states that amendment 25-45 to 14 CFR Part 15 in 1978 added to Part 25.571 "(e) the airplane must be capable of completing a flight during which structural damage occurs as a result of ... (2) propellor and uncontained fan blade impact. So there used to be a distinction between props and "uncontained fans"... but now the legal definition of propeller from 14 CFR Part 1.1 is "Propellor means a device for propelling an aircraft that has blades on an engine-driven shaft and that, when rotated, produces by its action on the air, a thrust approximately perpendicular to its plane of rotation..." Which encompasses the "uncontained fan" - it's really just a bunch of fancy propellor blades. I guess what I am getting at by throwing all of this FAA policy at you (which I had to research to make this comment, nobody memorizes that stuff lol) is that there isn't really a specific reg that the blade has to be contained today as far as I could find (at least in FAA)

    I thought, although reduced, the noise was still an unsolvable problem especialy after more restrictive noise reduction policies especialy in the EU. It is a general issue if you have some blade system rotating near some kind of edges. Be it second blade system, rotating or not, fins, or other kind of aerodynamicly acting edges and surcases. You know this kind of problem by pusher props as well. If you've noticed they've avoided talking about the noise issue for this system entirely.

This disc (or 2 discs) spin thr fastest and are very heavy, as they have to withstand very high centrifugal forces at high temperatures. I'm sure that Cfm and airbus are considering the failure modes. Now this might just be an educated guess, but I suspect that a broken prop blade could cause pressure hull breach, but it would not slice right through thr aircraft and cut electrical / hydraulic lines like a failed disc would. In aircraft design you have to reach a 10^-6 chance per flight hour chance of a catastrophic failure. I'm sure they can achieve that.

    Tupolev Tu-95 has twin propellers on a turbo fan ,,.. interesting tech, don't see how this is much different aside from the propellers

    Yes, you are right. I was stationed at Kadena Air Base at Okinawa, Japan. I had gone home for lunch right outside Gate 4. On the way back on my bicycle I heard a very distinct and different sound. I looked up and saw a Tu-95 bomber flying up Hwy. 58 maybe 100 feet AGL. You could easily read the markings on the aircraft. I waved and could make out them waving back. That A/C was very loud and you could definitely feel it as it flew over. Respect for the crews that can fly those and still function. Thanks for the reply.

    The open rotor technology is great but what happens if and when a material failure occurs? You have a lot of shrapnel moving at high speeds .With enclosed turbines the pieces are slowed down minimizing passenger injury.I wouldn`t want to be sitting by a window seat opposite these knife throwers.Not to mention they are loud as hell, ask the Russian bomber pilots.
