      Yes and no. Fatigue WAS a major issue in the early years of aviation, but now it is well understood. As long as you have a proper understanding of the material's properties and the stresses induced by the application, then you can design to forestall or eliminate fatigue cracking. Some materials (certain types of steel) actually have infinite fatigue resistance as long as the stresses are below a critical threshold. Stress cracks are not an issue where one can employ a combination of good design, good "life" testing, good operator training, and good inspection/maintenance procedures.

Its loss rate was more than double that of the war's other leading U.S. combat jets. Five Harriers were shot down and two pilots died.

      One likely reason the British Harriers had a higher accident rate is that they fly more low-altitude missions, leaving less margin of error. Another explanation may be that the current British Harriers use older, less reliable engines.

      At the same time, maintenance mistakes account for far fewer accidents in England. Rolls Royce, the British firm that makes the Harrier?s Pegasus engine, overhauls the Royal Air Force engines. The Marines handle this task themselves with the help of civilian mechanics. Also, Royal Air Force mechanics tend to be much more seasoned than the Marines and civilians who work on U.S. Harriers. Some British air force maintainers have 22 years of experience; some Marine maintainers are not yet 22 years old.


      So, the British pilots tend to fly more dangerous missions, whether in peace time or during war. The RAF treat the Harrier as a multifunction aircraft, and use it for missions that the US Marines would deem unsuitable for it. For example, in the Balkans, RAF Harriers have been used for precision bombing missions, whereas similar sorties flown by US forces tend to be with newer, faster and more capable aircraft, such as the F-15E, F-16, F/A-18, F-117A, etc.

      A like-for-like comparision of the maintenance records of the RAF/RN Harriers and the US Marine Corps Harriers is possible but, before you compare the records of the aircraft in the air, you first have to take into account their different usage profiles.

    Now they have an a/c which can not only take off vertically (or very sharply with high load), fly at 400mph and carry a ton of stuff. For it's role it beats the shit out of any helicopter (fast enough to do the job more fuel efficient, heavier loads,) and and cargo plane (no need for a JATO unit, can't run a C5 off a carrier).

    This new technology is (like the tilt rotor concept was) unproven, and requires a complex set of engineering decisions to be made to get it to fly safley (like the tilt rotor). In 20 years, with a few deaths, it might be great - but the tilt rotor is here now.

    FWIW there is now a commercial version of the V22 in prototype, the BA commuter aircraft. Small enough to land on helipads, but fast enough for intercity (and in Europe) international work.

      The cause of the Arizona accident that killed 19 Marines was a form of vortex ring state that formed around one proprotor that caused an imbalance of lift from one side to the other. The ship rolled sharply and nosed in. All helos are susceptible to VRS and it forms when you are travelling down too fast in combination with low forward airspeed. At the time, the Osprey had a vertical descent rate limit of 800 ft/min at low forward airspeeds. The ship in question was descending at ~2100 ft/min, almost three times the recommended rate. Pilot error. The other crash later that year was due to a combination of hydraulic and software failures that reduced the redundancy of some control systems.

      The VRS has now been shown to not be a symptom of tiltrotors only, its boundaries have been mapped out, warning sensors have been installed, and VRS exit strategies developed. In a helo, you just gain some forward speed or sideward speed. In a tiltrotor you have the additional option of tilting the nacelles a few degrees. In addition, plenty of improvements have been made to all sorts of subsystems and the computers have been through the cleaners to check for more bugs.

    You are correct. However, a paradigm change is in order here. The Osprey and the various rotary wing aircraft (helicopters) require two highly trained pilots and the aircraft themselves are very expensive. A vehicle like the Moller SkyCar does not require a highly trained pilot because you do not truly "fly" it. Thus, your combat soldier can fly it to a fighting location.

    Think in terms of mounted calvary instead of a troop transport truck. The SkyCars are much cheaper and faster. It would be easy to store and maintain a lot of the M-600's. The very modular design and very simple components would make it relatively easy to even do a field replacement of entire engines.

    I could see a modified version of the M-400 being used in scouting and pilot rescue missions.

    The Avro Arrow was a plane produced by Canada that was years ahead of its time. Unfortunately, because of the immense pressure from the U.S. (they didn't want Canada to sell the technology to other countries), the project got shut down.

    From the article you linked to:

    As costs rose, other divisions of the armed forces saw their own budgets cut, and even groups inside the RCAF in charge of European operations were worried that there would be no money left over for a new tactical fighter needed there. In-fighting soon reached the top of the military. In August 1958 the CSC advised the government to cancel the Arrow, and buy two Bomarc and 100 interceptors from the US, as well as constructing two SAGE control installations in Canada.

    The Avro Arrow was an interceptor designed at a time when everybody else was shifting to missles for anti-bomber defense. The plane's expense threatened funding for other programs, so it was killed in budgetary battles.

    Then there's this:

    The US is also often blamed for the demise, often with claims that the US aerospace industry was upset about the 'upstarts' in Canada that were making them look foolish, or alternately that they were hunting for Avro employees. A cursory examination of the historical record shows the falsity of this claim. Quite to the contratry, the US military was distressed at the prospect of losing a first-rate staff in their own North American ally, and even considered buying 50 Arrows to give back to the RCAF in order to ensure production.

    I know it's fashionable to blame the Americans for everything. Don't get me wrong, I find it quite entertaining. But you shouldn't be too quick to rule out the Freemasons or the Illuminati, or perhaps even something so mundane as internal politics.

As for the Osprey, the Army was at one point planning to procure 231 Ospreys, but they cancelled years ago, a good decision.

      The basic problem with the Osprey is the drivetrain. There are five gearboxes, three clutches, flexible shafts with multiple couplings, and in the Navy version, disconnect points where the wings fold. Most of this mechanical nightmare is part of the backup system through which one engine can power both rotors. The rotor/tilt wing system requires huge amounts of maintenance, enough that maintenance records have been falsified to make it look better. It's also a very expensive aircraft for its size.

      Despite this, Osprey crashes occur mostly for other reasons.

      • Software failure when recovering from a hydraulic failure.
      • Rotor stall blamed on pilot error, but reflecting a hole in the flight envelope at low speed operation.
      The Osprey may eventually become reasonably safe, but it will always be an overpriced maintenance headache.

      VTOL aircraft tend to crash even more then helicopters. The Harrier, the only VTOL produced in quantity, has many, many crashes on the record, especially with pilots in training.

    Some grip on reality is needed here. Especially for any article with a quote like, "It dawned on me that the key to survival and victory in today's battlefield is information," said Garcia That pearl of wisdom has been around in written form since Sun Tzu so what vaccuum has this person been working in? That aside look at the various conceptual flaws in the article.

    "nature can provide ready-made solutions." is a comment made in many fields including computer science. The problem is that nature developed solutions for a carbon based lifeform. Imitations in silicon, steel, polymers cannot hope to achieve the same results. Flocks of birds do fly but they also eat and their cells reproduce and die. Steel and silicon simply dissipate energy (with nothing close to a Krebs cycle for renewal) and wear out (since repair or replacement of steel or silicon is hideously demanding of energy). So on a very fundamental level, solutions found in nature do not completely translate to the current materials of technology. You can get aspects of them, like the imitation of flapping flight, but not the whole package.

    But lest you think, "Fine. We'll go with _some_ of the benefits." Think: what are they? The article says Flapping wings allow insects and birds to fly at low speeds, hover, make sharp turns and even fly backward. The latter cite trying to imitate a hummingbird's flight. A hummingbird's flight can already be imitated by helicopters and even the V-22 Osprey. But both the helicopter and the Osprey achieve the desired result (within bounds dictated by inertia and thrust-to-weight ratios) with a structure evolved for maximum efficiency given the materials i.e. the propeller. Even if you are utterly fanatic and feel that flapping is the way to go, consider further the imitation of a hummingbird. The birds virtually eat constantly. In fact, you could argue that the researchers haven't looked to nature very closely for their solutions. Even if you could translate the physical properties of a hummingbird to a machine, nature itself demonstrates that the energy requirements are huge for that type of flight. At least the researchers acknowledge this at the end of the article but the impression is more that it is an afterthought rather than an evident truth even before the research had started.

    And is the flapping flight really the goal of ornithopters in this article? In this article it's a flock of small, lightweight robots hovering over Martian land rovers and guiding them to places of interest that seems to be the pitch. So what advantage do ornithopters have over other "eye in the sky" objects like helicopters, blimps, gliders, or high power satellite cameras? There don't seem to be any.

    At this point one might even ask, how appropriate is a solution inspired by nature (on Earth) to the environment on Mars? Environments on Earth that are similar to Mars don't have an abundance of life because there isn't much to support the energy requirements of life. Therefore a solution based on "nature" is arguably inappropriate.

    And finally, Mars exploration has top priority at the CSA. Sorry but Canada officially bowed out of its option to participate in the Mars exploration program via lack of federal funding. Maybe some Canadian companies will keep their hand in without the CSA but odds are NASA will buy American, and why not?

    (As for the submitter's comments, let's put on our thinking caps people. What kind of ride would people in the hull of a flapping aircraft get? Replacement for the Osprey indeed!)
