  • BUSINESS OPPORTUNITIES FOR GUIDED DIVING ON SUBMERGED B-29

    WarbirdsNews has learned that the National Parks Service has decided to allow divers to visit the Boeing B-29 Superfortress which has lain on the bottom of Lake Mead on the border between Arizona and Nevada. As many WarbirdsNews readers will be aware, divers first rediscovered B-29A 45-21847 following a lengthy investigation in 2001.

    The Superfortress crash-landed on the lake on July 21st, 1948. It was involved in scientific experiments with the Upper Air Research Project to study the variation in solar radiation with altitude. The plans required the aircraft to measure the radiation profile from nap-of-the-earth to 30,000′ and back. Flying from Inyokern, California, the crew were performing one of the last scheduled profile flights of the day. They had just descended from the stratosphere, and were leveling out low over the lake, flying at 250knots. Unfortunately, the aircraft’s altimeter had an incorrect setting, and the lake was so smooth and reflective that judging altitude visually proved very difficult. The pilot thought he was at 300′, but he was actually so low that the propellers struck the water’s surface, and struck it hard. Three of the four engines tore from their mounts, while the fourth caught fire. The left wing and empenage received significant damage as well. The crew were able to skip their aircraft back up a couple of hundred feet, but flying on one, damaged engine was not an option, so they carefully set her down, tail first into the water. The bomber floated for a short while, long enough at least for the five man crew to safely take to their life rafts. Then she slipped beneath the rippling water and that was the last anyone saw of her for the next five decades.

    We’re running out of B-29s to restore. It would be nice if we could have a material condition survey conducted, and explore the possibility of salvage and restoration. Fresh water should have been a better environment than most.

  • Military Pallets, Boxes and Containers – Part 7 Air Despatch – Think Defence

    Air Despatch, air drop, heavy drop or aerial delivery, makes use of a range of specialist equipment such as containers and platforms (pallets) to get stores and vehicles directly to the point of need, quickly, from the air, exploiting one of the characteristics of air power, immediacy.

    Air despatch, or air dropping stores, is yet another of those subjects where its history is chock full of British military and industrial innovation but the present is hanging on by the skin of its teeth due to continued budget erosion and changing priorities.

  • Poll of the day

    We buried my father-in-law the Saturday after Thanksgiving. He was a WW2 veteran, 15th Army Air Force. The local chapter of the VFW did a great job as honor guard. Minutes before the service at the cemetery, the funeral director asked, “Who’s the oldest?” And so it was that the flag was presented to my sister-in-law.

    At my maternal grandfather’s funeral, the flag was presented to the second-oldest aunt, and there was a great deal of squawking about it. Consensus seemed to be that the oldest uncle (also a veteran) should have received it.

    At my oldest brother’s funeral, the one who received the flag was not the oldest, but the son currently serving in the Army. Everyone was fine with this.

    So my question is this:

    Just to keep the record straight, I think it’s fine that my sister-in-law received the flag. She had the lion’s share of caring for my father-in-law. I plan on giving her a display case for the flag. I just wondered if there’s a dominant tradition out there.

  • Boeing X-53 Active Aerolastic Wing

    NASA F/A-18 as the X-53 AAW.

    Today in 2006, was the first flight of the Boeing X-53 Active Aeroelastic Wing. While I’m aware of the Active Aeroelastic Wing (AAW) program and aware of the role the F/A-18 plays as NASA, including it’s roles as an airborne laboratory and as a chase aircraft, I had no idea that the AAW program had formally received an “X” designation:

     12/11/2006 – WRIGHT-PATTERSON AIR FORCE BASE, Ohio  — Air Force Research Laboratory researchers recently received word that the Active Aeroelastic Wing (AAW) flight demonstrator has been assigned the Mission Design Series number X-53. The designation makes it the first successful X plane initiated within the Air Vehicles Directorate since the X-24 lifting body concept, which was later employed on the Space Shuttle.

    The AAW program is control technology that uses wing flex (in the AAW program case of 5 degrees) in conjunction with conventional flying surfaces (ailerons, flaps and leading edge slats) to give increased control moments. This would mean less drag when these surfaces are moved at high speed, decreased structural weight. In a way the AAW comes full circle in aviation. The Wright Flyer used wing warping in much the same manner.

    The Wright Flyer used aerolastic "wing warping" as control services in flight.
    The Wright Flyer used aerolastic “wing warping” as control services in flight.

    As mentioned, the X-53 is a pre-production F/A-18 Hornet and the structural modifications to the aircraft are:

    The wings from NASA’s now-retired F/A-18 #840, formerly used in the High-Alpha Research Vehicle (HARV) project, were modified for the AAW flight research project and installed on the AAW test aircraft. Several of the existing wing skin panels along the wing box section of the wing just ahead of the trailing-edge flaps and ailerons were replaced with thinner, more flexible skin panels and structure, similar to the prototype F/A-18 wings.
    Original F-18 wing panels were comparatively light and flexible. During early F-18 flight tests, however, the wings were observed to be too flexible at high speeds for the ailerons to provide the specified roll rates. This was because the high aerodynamic forces against a deflected aileron would cause the wing to deflect in the opposite direction.
    In addition, the F/A-18’s leading-edge flap was divided into separate inboard and outboard segments, and additional actuators were added to operate the outboard leading-edge flaps separately from the inboard leading-edge surfaces. By using the outboard leading-edge flap and the aileron to twist the wing, the aerodynamic force on the twisted wing provided the roll forces desired. With AAW control technology, a flexible wing will now have a positive control benefit rather than a negative one.
    In addition to the wing modifications, a new research flight control computer was developed for the AAW test aircraft, and extensive research instrumentation, including more than 350 strain gauges, was installed on each wing.

    NASA’s 853, the X-53 AAW is one of the oldest F/A-18 Hornets still flying. This model in particular is one of the early production aircraft. Here’s photo walkaround of the X-53:

    No. 853’s nose is home to an array of navigation and guidance gear, along with research equipment like the Airborne Research Test System. ARTS  is a computer that allows engineers to quickly and easily test new software and equipment without installing a dedicated computer for each project. That gray box at the bottom of the nose is an ARTS.

    These tubes protruding from the wing spars of No. 853 once were connected to the static pressure sensors on the wing. The sensors measure air pressure over the top of the wing to help determine the airflow during various maneuvers. The lift generated by the wing is dependent on the flow of air around the wing. Engineers can better understand the effects of various tests such as the wing warping if they have a precise way to measure the air pressure over the wing
    nasaf1814_0
    No. 853’s left wing details the longest history of the plane’s role as a test mule. It bears little resemblance, aside from its shape, to the sleek, smooth wing the plane had when it left the factory. The wing is dotted with sensors, equipment and remnants of the epoxy-like material engineers use to hold everything in place.
    nasaf1815_0
    To accurately measure and monitor the wings during the project, sensors along the wing measured air pressure as well as strain on the wing structure.
    nasaf1816
    The blue box houses the transmitter and receiver that work in conjunction with the reflectors to measure wing strain. All of those sensors and other equipment require miles of wire, and No. 853 is packed with them.
    nasaf1819_0
    Small reflectors are placed along the wing. Light emitted from a transmitter along the spine of the airplane is bounced off the reflector back to the box, allowing engineers to precisely measure wing strain in three dimensions.
    nasaf1822
    NASA researchers found wing warping could produce adequate roll rates at transonic and supersonic speeds. The software control laws that manage warping to control roll offer several advantages over traditional roll control, including reduced drag and improved maneuverability. And perhaps counter intuitively, a lighter structure can be used because aerodynamic forces on the wing can be more closely controlled, reducing strain
    nasaf1825
    Aside from NASA’s test equipment, the X-53’s cockpit doesn’t differ that much from the production Hornet.

    You can learn a bit more about the X-53’s Wikipedia page here and from NASA itself at the X-53 fact sheet.

    It’s an interesting program with future technoloigcal applications to both civil and military airplanes.

  • A Time For Choosing

    I don’t really have  a dog in the Army/Navy game. It’s almost a foregone conclusion that Army will lose. And the only thing West Point ever did for me was send me 2nd Lieutenants. Some very good. Some very bad.

    But Ronald Reagan’s 1964 A Time For Choosing Speech just keeps getting better and better over the years. Any time someone argues our current President is eloquent, I want to slap some earbuds on them and play this.

  • Pearl Harbor: 5 things you didn’t know about the Coast Guard that day « Coast Guard Compass

    They told us that the pilot was dead (and) that he was killed by a Hawaiian during a fight with the Hawaiian, who started to grapple with the pilot, who was holding him at pistol point-blank range. The pilot fired his pistol three times hitting the native in the groin, thus enraging the Hawaiian who grabbed him around the waist and turned him upside down and smashed his head into the ground killing him instantly. The Hawaiian was a 6-foot 6-inch giant and the three shots to his groin apparently didn’t affect him that much. … We then got to inspect all the items they brought back with them. First there was the synchronized machine gun from the fighter plane, then the fish skin water proof wrapping that the pilot had wrapped around his waist … (containing) local maps, money and things necessary if he had to bail out over Oahu. The machine gun still had about twenty bullets hanging from the breach of the gun. I snapped one of the cartridges from the belt figuring it would be a easy souvenir to keep. I asked where was the pilot and they told me that the wounded Hawaiian they brought aboard had killed him and that the natives were going to bury him on the Island. They thought that the stuff they took from him would be enough to verify that he had been taken care of.”

  • Leftists become incandescent when reminded of the socialist roots of Nazism – Telegraph Blogs

    On 16 June 1941, as Hitler readied his forces for Operation Barbarossa, Josef Goebbels looked forward to the new order that the Nazis would impose on a conquered Russia. There would be no come-back, he wrote, for capitalists nor priests nor Tsars. Rather, in the place of debased, Jewish Bolshevism, the Wehrmacht would deliver “der echte Sozialismus”: real socialism.

    Goebbels never doubted that he was a socialist. He understood Nazism to be a better and more plausible form of socialism than that propagated by Lenin. Instead of spreading itself across different nations, it would operate within the unit of the Volk.

    So total is the cultural victory of the modern Left that the merely to recount this fact is jarring. But few at the time would have found it especially contentious. As George Watson put it in The Lost Literature of Socialism:

    It is now clear beyond all reasonable doubt that Hitler and his associates believed they were socialists, and that others, including democratic socialists, thought so too.

    The clue is in the name. Subsequent generations of Leftists have tried to explain away the awkward nomenclature of the National Socialist German Workers’ Party as either a cynical PR stunt or an embarrassing coincidence. In fact, the name meant what it said.

    via Leftists become incandescent when reminded of the socialist roots of Nazism – Telegraph Blogs.

    Daniel Hannen is quite possibly the only useful member of the European Parliament.

    I think he gives too much credit to his current opposition, and ironically, after telling us to listen to what Hitler said, refuses to hear what his contemporary political opposition says.

    But the general theme of his piece is correct.

  • Osprey APKWS

    Aviation Week & Space Technology has the story, but it’s behind the paywall.

    A Marine MV-22B fires an APKWS guided rocket during trials.

    The APKWS is the Advanced Precision Kill Weapon System. You have to look fairly closely to see the rocket leaving the pod mounted to the port cheek of the fuselage.

    APKWS takes an unguided 70mm Hydra rocket. Hydra rockets are modular. There are various motor and warhead configurations that can be mixed and matched.  The APKWS is a guidance section. Unscrew the warhead from the motor section, screw the APKWS to the motor, and the warhead to the guidance section. Suddenly, you have a guided missile that’s very precise, and has a much longer effective range than an unguided rocket. It has a small warhead, but its quite sufficient to take out a truck, other unarmored vehicle, gun emplacement or similar target. And it is comparatively cheap, as opposed to say, a Hellfire missile.
