No matter what is currently going on in aviation, everyone always asks, What is next As you probably have learned from this site, or others like it, helicopters have a very limiting factor common to all of them Airspeed. The question for many has always been how to get around this limitation. How do we make a helicopter that will take off vertically and go faster than conventional helicopters, then land again vertically as it took off One answer to this question has been the very successful AV 8 series of airplanes known as the Harrier.

No matter what is currently going on in aviation, everyone always asks, What is next As you probably have learned from this site, or others like it, helicopters. A helicopter is a type of rotorcraft in which lift and thrust are supplied by rotors. This allows the helicopter to take off and land vertically, to hover, and to fly. This form is for our existing customers, students, employees and airport neighbors to provide feedback on matters related to our operations. The form is anonymous and. V FM 1112 PREFACE This manual is the Armys doctrinal manual for attack helicopter operations. It is designed to assist attack helicopter commanders, their staffs. Helicopter Operations Manual' title='Helicopter Operations Manual' />While the AV 8 Harrier has been a success for military operations, it is impractical for civil use due to the large quantities of fuel required to maintain a hover and the amazing amount of noise produced by the engine to maintain vertical flight. Other projects have been undertaken such as the Advancing Blade Concept ABC, The Cheyenne Project and numerous Tilt wing aircraft. None of these concepts were pursued to completion for one reason or another. Another project that was attempted was the Fairey Rotodyne Gyroplane concept project which was successfully flown, but had many noise problems as well and was never really accepted for civilian use. This is the Advancing Blade Concept aircraft. Notice that it looks a lot like both an airplane and a helicopter. Brown Skinned Girl Chris Brown Downloads. The side mounted jets were to push the aircraft along using jet thrust as the primary means of propulsion. It has contra rotating Contra. One on top of the otherto eliminate retreating blade stall characteristics. This Tilt wing design is unlike the Tilt Rotor in that the whole wing tilts and not just the engine nacelles. A design like this loses the lift generated by the wing at lower speed and is less versatile than a pure Tilt Rotor design. The engines could only lift it straight up and it had no form of helicopter controls. The Rotodyne used jet thrust at the rotor blade tips to propel the rotor to a high speed for takeoff and landing. The rotor would be unloaded in flight and the aircraft would fly like an airplane at cruise speeds. The major problem with this was the noise created by the jet powered rotor system. Enter the V 2. 2, one of the most controversial aircraft to ever be built and go into production. The V 2. 2, commonly called the Osprey, is controversial because it is new, it is different, and it is a true innovation. By its nature the V 2. First, lets look at what it is. The V 2. 2 is a twin engine tilt rotor helicopter airplane combination aircraft. The two engines are interconnected. The counter rotating airfoils at the end of each wing Called prop rotors are used as propellers in forward flight, and as articulated rotors in vertical take off and landing modes. It uses. the concepts of differential collective pitch used in tandem rotor helicopters, rotor tilt concepts used in single rotor helicopters, the concept of. This aircraft has a lot to. Here is the real kicker The whole thing folds up automatically to take less space on military ships. See the photo lt Left. What makes the V 2. This aircraft has safety built into every aspect of its design. Some examples of this are the triple redundant hydraulic systems with an added. The composite fuselage structure has a metallic wire mesh. The prop rotors have lights in the rotor tips for night safety and de icing blankets built into them. They. are designed to fail in such a way that they will turn into strands of composite material upon impact Broom Stranding. This eliminates the hazard. The engine and transmission systems have double, triple and. The aircraft can fly with any degree of nacelle tilt in both single and multi engine modes. This would. pose a lubrication problem for the engines if a dual lubrication system were not installed for the level and tilted engine modes of flight. Should the lubrication system run completely dry, the aircraft could fly for an additional 3. The nose of the aircraft was designed as an anti plowing structure and the panels on both sides of the cockpit are ballistically jettisonable for rapid egress of the cockpit crew. In a high impact landing, the wings are designed to fail outboard near the engines so wing structures will not contact the fuselage. The self sealing fuel system has self closing safety fittings and breakaway fuel lines designed to contain the fuel in a high impact situation and reduce the hazard of post crash fire. Dual automatic flight control systems monitor and adjust control inputs to reduce the workload on the pilots. And this is just the tip of the iceberg. There are so many safety systems built in to this aircraft, one person could not begin to tell you all about them. Click for a larger picture. V 2. 2 Specifications Graphic. So then, why all of the controversy Even though all of the safety information about the aircraft is readily available, some critics of the aircraft still say it is unsafe by design. I have. read numerous articles concerning the safety of the aircraft, which make claims about the susceptibility of the rotor systems to encounter a. Vortex Ring State. For those of you familiar with Settling with Power Also known as Power Settling in the Naval Aviation. Vortex Ring State is the re circulation of air within the rotor system that makes Settling with Power the. Basically, the rotor system is processing the same air continuously and is not producing enough lift to maintain hovering flight. Is Vortex Ring State or Settling with Power unique to the V 2. No, it is not unique at all. Every helicopter can get into it if the situation is allowed to exist. There are three conditions that must exist for Settling with. Power to begin Significant power applied Always present at a hover, a descent rate greater than 3. If. descent rates are not allowed to become excessive, then the aircraft will usually not settle into its own downwash. Why is Vortex Ring State such an issue with the V 2. To explain this, let s make a comparison to the most similar aircraft available, the CH 4. D Chinook. The V 2. Boeing web site for vertical takeoff. The CH 4. 7 also has a 5. The. V 2. 2 uses two engines that produce around 4. Shaft Horsepower Almost 5. USN and USAF models and almost 6. SHP for single engine. The CH 4. 7D also has two engines that produce 4. SHP. The engines on the V 2. The Chinook also has the engines interconnected so it too can power both rotors with both engines or just one engine. The main differences between the two aircraft are that the V 2. The V 2. 2 uses two 3. Chinook uses two 6. Basically the V 2. Some of the difference is made up in the design of the prop rotor and the overall surface area of. Because the V 2. Settling with Power. Another factor, which could possibly contribute to the creation of Vortex Ring State, is the location of the rotors. On a Chinook, the rotors overlap. On the V 2. 2, the rotors sit at the same height, and are side by side at the. In certain crosswind conditions during a rapid descent, the rotor wash from one system could effectively be blown into the other. One VERY IMPORTANT thing to point out here is that the V 2. Settling With Power Army or Power Settling Navy, has a unique ability to get out of it. It does so without aggravation of the situation that normal helicopters do not have.
