  1. Admittedly, this might be defined as a science fiction scenario, however on the same token my friend, the same helicopter in the same situation is on a mission to pick up or rescue victim(s). It is my thought the efforts and mission being similar might be at least be considered. Some technical equipment's might find there way to the drawing board this way,
  2. Well, anyway is just a thought, but I am talking, "perfect storm", there was an attempt at refueling that failed, . . That turned out to be a disaster, I am thinking if a tank could have been delivered then a successful refueling may have occurred. Anyway last time I checked I did not find anything on the use of this technique.
  3. I do Innovation Research in the Helicopter ER & SAR technologies. It has come to my attention that in ER and SAR helicopter missions, there maybe cases when an alternative to Mid-Air Refueling can be used, . . The technology I am referring to is a pre-planned fuel delivery system, where a fuel tank can be delivered to a GPS location. This would mean a tank would be delivered to land or sea, and the chopper in a hoover above the tank can tap into the resource by connecting up and re-fueling from this source. This scenario has some usefulness and advantage over mid air refue
  4. If you say so, . . but then again, . . That's just the point, from some information I've been exposed to some rescues don't go off at night. I didn't see any wires walls or other obstructions that the mission is hampered by. Let me search around for a flash flood rescue, and I know there are more, I'm a little busy but give me time, I'll spend a couple hours this week locating some, "pendulum effects" reports. I'm not trying to pull off a hard or soft sell, I am just convinced with increase use of helicopter rescue, we will see or hear of more incidents.
  5. Thanks Chris, In other words, without reading any further, I assume that as you say it is up in the air concerning the, "swing effect", concerning the time and effort to correct, . . the point I am getting at , is as viewed in some commentaries showing the, "swing effect", is the time and distance, allowable, for example, when a rescue mission is involved with close quarters such as, where there are electric wires, stone walls, cliffs, fires and the like, the un-practicabilities, leave a certain risk factor. In these cases the time and distance to ,"correct", may be vital to the success of t
  6. Concerning technical terms in the following; CIFER - Externally Slung Loads - Ames Research Center, Moffett Field In the Abstract the following; Flight test certification of helicopter-slung load configurations can be time consuming and expensive when quantitative evaluations of the system’s handling qualities, stability, and envelope are required. These costs can be significantly reduced by conducting the analysis during the flight test using telemetry data. The analysis is done following the completion of a test point and prior to clearing the aircraft to the next test point. A method
  7. I will continue this conversation in hopefully a more technical nature, . in the Aerodynamics, Mechanics, or other... forum Discussions as Rescue Line Pendulum Effect.
  8. Thanks Much to you all, . . I will post back any progress.
  9. The wet suit model is for wet suits and would be the same material, . .The hard cap for the rescue swimmer would be made from elastic form fit material and not necessarily foam, however the rescue swimmer may have less need to be submerged, the helmet part would be form fit, and therefore would need to be designed with live model fitting etc. The idea is to protect the rescue swimmer from head injuries as per incident data which I do not have but received comments from Naval personnel involved in such developments. I did post this in the LinkedIn group ; US Navy Search and Rescue (SAR) Swi
  10. I'd like to know, Whats the story on Rescue swimmers head gear, my understanding is that there is a need for head protection concerning helicopter rescue swimmers. I have viewed the prospective problems and have developed a concept, . . .As a developer, I'd like to know what you think about this.
  11. Yep, I did the graphics, to illustrate the incident as seen in a documentary years ago, etc. I think Expensive will be what it is, but I don't think that should prevent the inevitable improvement, as envisioned. Before I make any definite promises, I am taking my concept to an aero-engineer, etc. but I'm still talking 1-3 second electro-mechanical control and or prevention. Thanks for your reply and thanks to all others, there is ample information to keep me busy, . . much appreciated.
  12. First I am not trying to solve a problem that doesn't exist, . . I am fact finding zero tolerances for error. Secondly I am not trying to be a know-it-all, but the growing needs for SAR and ER will become more complex, in all dimensions. If you think that there is enough time to correct "swing" in hazard area, fine, . . I will look into the reference for the solutions as you have made reference, etc. The following graphic is only to illustrate the situation as it, has, can and will occur. I am talking 1-3 SECONDS AUTOMATED CORRECTION WINDOW. ///////////////////////////////////
  13. Chris, It seems that the report concerning, "oscillation" which I have referred to as, the "Pendulum effect", or "line-swing", is at the discretion of the pilot, when it comes to incident reporting. My concern is in the development of avionics to solve the problem. The following is an explanation that concern one of the present day. "seat of the pants" solutions as explained by one pilot. Subject: Re: Pendulum Whenever a helicopter pilot has an external load that starts to swing (Human or non-human cargo), he will begin to slowly turn and the swinging will cease. Initiating a shallow
  14. Sorry my friend, the last thing I want to do is seem disrespectful of pilots, that comment was left over from a forum I said the same thing and the members were executive types from the Helitech group in Linked in. Anyway what I mean about technical improvement people in the field are to make, without information that concerns incident reporting, that to me is the difference between a development that can "save lives", it is necessary because without the info there is hardly anyway for the people who want to assist and improve to do so. In this case, the reference here is, . . I was info
  15. Can you tell me what the situation is, when a rescue swimmer on the line is at sea level and the line would extend under and across to the opposite side of the helicopter. How do you deal with that ? Also; I just emailed Textron concerning;. . Pilot Simulators, are not programmed for the incident of, "line swing" or "Pendulum effect", is there anyone supporting R&D in this field. I am a free lance designer in SAR development, and would really like to know, also there is no requirement for incident reporting for helicopter pilots, that's a big no-no ! How important is that to you
