Postwar Aircraft Projects / Re: Miles Aerovan variants?

You're welcome!  One caveat, as it was nagging at me that I thought that they had tried retractable, external airfoil flaps on something.  Per Wikipedia:

Quote
In 1944 the prototype [M.38] was rebuilt as the M.48 Messenger 3 with fully retractable electrically-operated split trailing-edge flaps and a 155 h.p. Cirrus Major III engine. This model was not further developed as it did not provide any advantage over the other variants.

Recently posted on YouTube by NASA Armstrong Flight Research Center (Edwards AFB), December 12, 1969 footage of the remote controlled flight (piloted by Milt Thompson on the ground) of the Hyper III, after being dropped from altitude by a "borrowed" US Navy Sikorsky SH-3 Sea King helicopter (piloted by Bruce Peterson).

Good Day All -

There's no one specific X-24C thread that I can find and of the threads that mention the X-24C, this seems the best fit for this McDonnell Douglas images.  The three photos are from a collection donated to the Museum by a retired McAir Engineer.  Not sure of this was tunnel tested as part of McAir's own hypersonic projects or done as a contract.  Noe the dates on the 2nd and 3rd images.

Enjoy the Day!  Mark

Good Day All!

Here are a few of the negative scans - thoughts on whether this is Model 192, Mach 12 Demonstrator or?!?!

Enjoy the Day!  Mark

Per the latest SAR summary, it looks like the extended range GMLRS variant (150 km range with room for payload growth)
is more definite:

Guided Multiple Launch Rocket System/Guided Multiple Launch Rocket System Alternative Warhead (GMLRS/GMLRS AW) Program costs increased $734.1 million (+10.74%) from $6,834.0 million to $7,568.1 million, due primarily to increased production capacity (+$386.5 million), development of the Extended Range GMLRS (+$372.3 million) , a revised estimate to reflect the actual cost of production units (+$82.1 million), support for GMLRS variants (+$20.0 million), and revised escalation indices (+$5.0 million). These increases were partially offset by accelerating the procurement buy profile to meet maximum production capacity of 6,000 rockets in FY 2018 (-$93.3 million) and acceleration of production activities in FY 2022-FY 2029

At MAST Asia 2017 (Maritime Air Systems & Technologies), the naval defense exhibition currently held in Tokyo, Japanese company Mitsui Engineering & Shipbuilding (MES) unveiled a new Landing Platform Dock (LPD) concept.

Mitsui's LPD is designed for large scale transportation of LCACs, MBTs, vehicles, cargo and equipment, with multi-mission features. MES drew on its experience from constructing and delivering "Osumi" and "Shimokita" LPDs to the JMSDF when designing the new LPD.

Company representative didn't want to provide specific details, but based on a MES brochure the LPD has a deck with two helicopter spots and a hangar large enough to receive two V-22 Osprey tilt-rotor aircraft and a small size VTOL UAV (similar in size to the MQ-8B Fire Scout).

The LPD is fitted with a well deck large enough to accommodate two LCACs. Vehicles can be stored on two decks. Total vehicle capacity is classified, however, based on an image in the brochure, up to 40 vehicles (including AAVs, MBTs and APCs) may fit on the lower deck. The image might be conceptual so this figure may not be an accurate data.

In terms of systems, (based on the brochure) Mitsui's LPD is fitted with a Phalanx CIWS forward and a SeaRAM launcher on top of the helicopter hangar. There are two shafts and two rudders, as well as two bow thrusters. The hull form also features two retractable fin stabilizers.

The Japanese LPD concept measures 210 meters in length, 30 meters in width and 7 meters in draft for a displacement of 16,000 tons and a speed of 22 knots. The maximum complement of the vessel is 200 people (including troops). For comparison, the US Navy's San Antonio-class LPD displaces over 25,000 tons eventough it is roughly the same size (208 meters in length and 32 meters in width).

According to Mistui, the main missions of the LPD include island defense as well as humanitarian assistance / disaster relief.

The Japan Maritime Self-Defense Force (JMSDF) is reportedly looking to boost its amphibious capabilities in order to protect its Southern Islands.

At MAST Asia 2017 (Maritime Air Systems & Technologies), the naval defense exhibition currently held in Tokyo, Japanese company Mitsui Engineering & Shipbuilding (MES) unveiled its Mobile Landing Platform (MLP) concept.

Mitsui's MLP is designed for large scale transportation of LCACs, MBTs, vehicles, cargo and equipment, with multi-mission and modular features. In addition to its aviation operations and amphibious capabilities, this MLP can act as an offshore base.

The design differs from the American MLP which comes in two variants: The Expeditionary Transfer Dock (ESD) variant for amphibious operations and the Expeditionary Sea Base (ESB) variant focusing on aircraft operation. Mitsui's design appers to combine both roles on a single design.

Unlike the ESB, there is no aviation hangar forward. There are four helicopter spots on the "almost" flat top. There is an elevator for stores and equipment next to spot #2. There is also a ramp allowing vehicles access between the two main decks.

The Japanese MLP concept measures 240 meters in length, 39 meters in width and 7 meters in draft for a displacement of 21,000 tons and a speed of 15 knots. The maximum complement of the vessel is 240 people.

According to Mistui, the main missions of the MLP include island defense as well as humanitarian assistance / disaster relief.

The Japan Maritime Self-Defense Force (JMSDF) is reportedly looking to boost its amphibious capabilities in order to protect its Southern Islands. MES, which delivered "Osumi" and "Shimokita" LPDs to the JMSDF a few years ago, also unveiled a new LPD and a new LHD design at MAST Asia. Navy Recognition will be covering these designs soon.

MLP designs and the "sea basing" concept in general seems to be getting popular outside of the US. You may recall from our LIMA 2017 coverage that the Royal Malaysian Navy is also exploring (and using to some extend) this concept.

At MAST Asia 2017 (Maritime Air Systems & Technologies), the naval defense exhibition currently held last week in Tokyo, Japanese company Mitsui Engineering & Shipbuilding (MES) unveiled a new Landing Helicopter Dock (LHD) concept.

Mitsui's LHD is designed for large scale transportation of LCACs, MBTs, vehicles, cargo and equipment, with multi-mission features. MES drew on its experience from constructing and delivering "Osumi" and "Shimokita" LPDs to the JMSDF when designing the new LHD.

Company representative didn't want to provide specific details, but based on the MES brochure, the LHD has a flat top with five helicopter spots and a hangar large enough to large helicopters such as the CH-47 Chinook tandem rotor heavy-lift helicopters.

The LHD is fitted with a well deck large enough to accommodate two LCACs. Vehicles can be stored on two decks. Total vehicle capacity is classified, however, based on an image in the brochure, at least 24 AAVs may fit on the lower deck. The image might be conceptual so this figure may not be an accurate data.

In terms of systems, (based on the brochure) Mitsui's LHD is fitted with a Phalanx CIWS forward and a SeaRAM launcher at the stern. There are two shafts and two rudders, as well as two bow thrusters. There is a main elevator for helicopters aft and a smaller one for stores and equipment forward, near the island.

The Japanese LHD concept measures 210 meters in length, 35 meters in width and 7 meters in draft for a displacement of 16,000 tons and a speed of 22 knots. The maximum complement of the vessel is 200 people (including troops). For comparison, the French Navy's Mistral-class LHD displaces over 20,000 tons eventough it is slightly smaller in size (199 meters in length and 32 meters in width).

According to Mistui, the main missions of the LHD include island defense as well as humanitarian assistance / disaster relief.

The Japan Maritime Self-Defense Force (JMSDF) is reportedly looking to boost its amphibious capabilities in order to protect its Southern Island.
