hobbitcid Posted July 9, 2015 Share Posted July 9, 2015 (edited) From the weird side of aviation... According to the web site, the idea of an Amphibious C-130 was considered back in the early 70's... or is it fake? Can't tell these days... Anyway its an interesting diversion. http://foxtrotalpha.jalopnik.com/a-c-130-hercules-amphibian-makes-too-much-sense-to-be-t-1716610531 Edited July 9, 2015 by hobbitcid 1 Link to comment Share on other sites More sharing options...
HerkPerfMan Posted July 9, 2015 Share Posted July 9, 2015 (edited) It's all true. I saw design reports on the earlier flying boat, and I remember seeing photos of wind tunnel testing with the later float plane model. It always seemed to me like a natural extension of the C-130 design, especially the flying boat design. Trust me, anything you can possibly imagine bolting on a Herc has already been thought up...and thoroughly analyzed.

HerkPerfMan Posted July 9, 2015 Share Posted July 9, 2015 (edited) Here's the closest flying boat in reality: ShinMaywa US-2. Operated by Japan and in production. It's a little smaller than a C-130J, but uses a variant of the AE2100 engines and 6-blade Dowty props.

M2 Posted July 10, 2015 Share Posted July 10, 2015 Old news... NAVAL AIR STATION PATUXENT RIVER, MARYLAND 20670-5400 PUBLIC AFFAIRS DEPARTMENT TELEPHONE: (301) 342-7512 DSN 342-7512 FAX (301) 342-7509 RELEASE #97-131 Aug. 18, 1997 NAVAL AIR STATION PATUXENT RIVER, MD - - - Officials at the Naval Air Warfare Center Aircraft Division recently announced the latest variant of the ubiquitous C-130 Hercules, the C-130 Floatplane. The C-130 Floatplane is proposed as a low-cost modification to existing aircraft which would add considerable flexibility to logistic, special forces, and other missions. It would have field installable amphibian floats replacing the landing gear on C-130E/H/J models allowing open ocean, beaching, and hard surface operation without the need for a dedicated seaplane. For the last two years, the warfare centerís aircraft division has contracted to Lockheed Martin Aeronautical Systems to perform a feasibility study and a technology risk reduction effort. These were done to identify and quantify the risk areas: hydrodynamic drag and impact loads, spray patterns, and aerodynamic stability. To mitigate this risk, a subscale model with a radical split float design was built and tested. The split float eliminates inboard spray, deflects outboard spray clear of the props and wings, reduces water impact loads, retains full cargo ramp operation, and has excellent sea-keeping qualities. Tow tank tests showed that water impact loads were lower than expected allowing sea state three operation. Drag was acceptable and spray patterns were excellent. Computational Fluid Dynamic Analysis indicated that aerodynamic stability degradation is within acceptable limits. Payloads up to 27,000 pounds and ranges more than 2,200 nautical miles with 10,000 pounds of cargo are possible. The C-130 Floatplane opens vast new missions that were formerly not feasible.

hobbitcid Posted July 10, 2015 Author Share Posted July 10, 2015 (edited) From aviation week - http://aviationweek.com/defense/lockheed-martin-offer-converted-c-130js-maritime-patrollers The article requires free registration. So excerpts from the article: Lockheed Martin To Offer Converted C-130Js As Maritime Patrollers " RNAS YEOVILTON, U.K. — Lockheed Martin is to offer a U.K-specific variant of its SC-130J Sea Hercules to Britain, as the U.K. looks to re-generate a maritime patrol capability." "The company says it could convert the U.K. Royal Air Force’s existing fleet of C-130J airlifters into SC-130Js, reducing procurement costs and technical risks, company officials told Aviation Week on the eve of the RNAS Yeovilton Air Day." "The company plans to formally announce its plans in the coming weeks. If selected, the British Sea Hercules’ would be fitted with the same mission system fitted to the Royal Navy’s AgustaWestland EH101 Merlin Mk. 2 helicopters, which were upgraded by Lockheed Martin as part of the U.K. defense ministry’s Merlin Capability Sustainment Program. Currently the Sea Herc is being offered to international customers with Lockheed’s Artamis mission system, which was developed for use on the P-3 Orion." I think the Herc may actually outlast the B-52... Edited July 10, 2015 by hobbitcid Link to comment Share on other sites More sharing options...

JarheadBoom Posted July 12, 2015 Share Posted July 12, 2015 Here's the closest flying boat in reality: ShinMaywa US-2. Operated by Japan and in production. It's a little smaller than a C-130J, but uses a variant of the AE2100 engines and 6-blade Dowty props. Back in '96 at the MCAS Futenma Open House/Flightline Fair, the Japanese (Coast Guard??) brought in a US-2 for static display. Older one (obviously...), with T-56s and 3-blade props. I got to walk/climb through it with a very enthusiastic crew member as an escort, and just like every other Japanese military aircraft I've ever been on, you could safely eat off of just about any surface of the aircraft. It truly was that clean. Not a spot of corrosion visible, either. Monday morning I made sure I was out on the line when they departed. Very little pitch change at rotation, but it looked like it just levitated off the runway after about a 1500ft roll. It reminded me of a Harrier rolling takeoff, just much slower & quieter. With the AE2100s and 6-blade props the newer ones must climb like an elevator... Link to comment Share on other sites More sharing options...
Clark Griswold Posted May 11, 2016 Share Posted May 11, 2016 (edited) Thread relight. Found some gems on the Herc on Water concept the USN researched in the 60's & 70's... http://www.secretprojects.co.uk/forum/index.php?topic=26090.0 and on the C-130 float plane pitched in the 90s: https://www.flightglobal.com/pdfarchive/view/1996/1996%20-%202626.html We NEED a Float Plane Herc or Sea Plane Herc, this is a national security issue, trust me Congress, just fund it.

Clark Griswold Posted May 18, 2016 Share Posted May 18, 2016 More seaplane ideas for the venerable Herc, retractable floats with testing done on 1:6 RC models from Tigerfish Aviation in Australia. Thought this was another Stavatti but the company seems legit. Where do we send the check? http://www.tigerfishaviation.net/index.html Link to comment Share on other sites More sharing options...
