UB-06 "Yang" Stealth Bomber
Introduction
When the Shaitan Corporation started the new bomber program, they were looking for one thing; innovation. The new UB-06 "Yang" Stealth Bomber now provides the armies supplied by the Shaitan Corporation an ordinance delivery system like none other in the world. Fusing a number of current technologies with a number of brand new innovative aviation and aerospace technologies, the new UB-06 "Yang" delivers the best in stealth and speed. Consequently, both stealth and speed were put in mind when designing the new bomber, all the while still being able to deliver a large payload. The Air Force claims the Yang Stealth Bomber to be one of the last manned bombers in the military, and even feature a faster (albiet more expensive) variet to be introduced later.
The Design
The new Yang Stealth Bomber provides innovative technologies all the while retaining a sleak and stealthy design. As if it were something straight out of a science fiction movie, the UB-06 Yang Stealth Bomber links its future design to its low radar signature. the design of the aircraft has continuous curves. Many of of the surface shapes of the UB-06 are curves with constantly changing radii. These scatter radar beams in all directions instead of back to the radar source. There are no right angles on the exterior of the design. The leading and trailing edges of the wing and tail have identical sweep angles (a design technique called planform alignment). The fuselage and canopy have sloping sides. The vertical tails are canted. The engine face is deeply hidden by a serpentine inlet duct and weapons are carried internally. The design as with the SC-14 fighter-bomber stop virtually all regular radar, visual, acoustic, and electro magnetic signatures from returning to the sending antenna.
If that were not enough, the most innovative feature of the Yang's stealth is its composite materials. Aside from new composites to protect the aircraft from the new high speeds, the Shaitan Corporation created a new radar-absorbing material to be fitted exclusively to the new line of Stealth Bombers. The material, although expensive, reduces virtually all current radar waves including current systems of Over-the-Horizon to a near zero. Esentially, if any radar signature is caught by current systems, the return signature would read the plane as if it were a haze, cloud, or small flock of birds. Also present in the Yang, are a number of other systems to reduce IR and visual signature of the plane also; such as high powered lasers for blinding certain weapons, the SH/AFE-05 system, flickering skins, blurred edges, and even active camoflauge that continuously changes to match it's environment. This gives the military an unprecedented level of stealth, being able to enter airspace, deliver the ordinances and exit without the enemy ever knowing who dropped the bomb.
The SH/AFE-05 is a new "Active out-of-phase emission" system, designed for the Air Force rather than the Navy. Reduction of radar cross section of nozzles is also very important when it comes to stealth, and is complicated by high material temperatures. The approach taken by the Army is to use ceramic materials. The ceramics may be either lightweight, parasitic sheets mounted on conventional nozzle structures or heavier structural materials forming saw-toothed edges.
Also, the cockpit. The pilot's head, complete with helmet, is a major source of radar return. This effect is amplified by the returns of internal bulkheads and frame members. The solution is to design the cockpit so that its external shape conforms to good low radar cross section design rules, and then plate the glass with a film similar to that used for temperature control in commercial buildings. Here, the requirements are more stringent: it should pass at least 85% of the visible energy and reflect essentially all of the radar energy. At the same time, one would prefer not to have noticeable instrument-panel reflection during night flying. On-board antennas and radar systems are a major potential source of high radar visibility for two reasons. One is that it is obviously difficult to hide something that is designed to transmit with very high efficiency, so the so-called in-band radar cross section is liable to be significant. The other is that even if this problem is solved satisfactorily, the energy emitted by these systems can normally be readily detected.
A lot of the structural material itself is made from carbon composites to reduce the weight and help increase the overall speed and preformance, but much is also made from Titanium composites, which although more expensive, the costs are made up for themselves with low maitenence costs; which gives the plane a further weight loss, and better overall preformance. Also, much of the outside layers, and that of the wings are made up of a special composite made by the Shaitan Corporation itself to protect the plane from its high speeds. It is made up of a number of different top-secret polymers reinforced by carbon fiber bismaleimide (BMI) which helps to protect the plane from high temperatures and the pressures of the soaring winds. Not only the new polymer is there to help from the plane from simply disentegrating in mid flight from such high speeds; the bomber's structural design itself helps combat such discrepencies and the curvature of the aircraft allows it to consolidate its scramjets. Also instituted is an active cooling system which coolant circulates thoughout the vehicle skin.
The engines are that of the newest in scramjet/TurboRAM technologies. Scramjet technology is relativey simple, fuel efficient (fueled by hydrogen), and even economical (because that the materials required for construction are somewhat reasonably priced), and is able to have a range in excess of 10,000 miles (although infinite if refueled in-air) and a cruising speed of 8.5 miles per second (Mach 10). The bomber would take off from a conventional runway, and then use scramjets to accelerate to Mach 10 while climbing to 115,000 to 120,000 feet, where the air-breathing engine would be shut down as the aircraft left the atmosphere. The aircraft would at this point continue to climb to about 200,000 to 250,000 feet, using its own momentum, and then make a descent back to around 200,000 feet. At this altitude, it is out of range and too fast to be hit by any and all SAM systems or virtually any other current air-to-air missiles. The aircraft would fire its engine every 20 or 30 seconds after that, the aircraft would quite literally surf though the air on its own shockwave, like a rock skips across a pond. The turbofan portion of the TurboRAM is duel-spooled, to allow a boost to the existing ramjet engine to further its maximum speed and excellerate it to a speed which the scramjet engine could be initiated. Also, the TurboRAM has splitted exhausts and a straight-edged engine muscle chassis to lower wind impact.
Avionics
The UB-06 Yang and the SC-14 Puca both contain one of the most advanced ever integrated avionics and software systems. It is linked, as all units are, to the military's Network Centric Warfare System, that connects all units into a universal program of 'harmonic tactics' (as explained in the Kuan Ti Infantry System section). Pilots of the Yang can communicate with units of sea, ground, air, and even space with it being included in the new system. The Yang along with all other aircraft and sattelites can send images to the ground units and be displayed by the HUD systems. Such technologies can warn ground units of incoming enemy forces.
It also uses integrated avionics, where the radar, weapons management system and electronic warfare system work as one, giving the pilot unprecedented situation awareness. This is contrary to most of other aircraft systems that have a so-called federated systems architecture. This means that each avionics function has its own processor and essentially works independently. What that does is make the pilot the integrator of data and the manager of all the supporting subsystems, distracting him/her from more relevant tasks during air-combat. The Yang avionics concept however, integrates all of the various systems like radar, communications, navigation, identification, electronic warfare, stores management, sensor control and the displays that are the primary means of communication with the pilot. Using the power of the onboard computers, coupled with the extensive maintenance diagnostics built into the Yang by the maintainers, that workload has been significantly reduced. The idea is to relieve pilots of the bulk of system manipulations associated with flying and allow them to do what a human does best – be a tactician.
The Yang features one of the most powerful on-board computers ever to be designed for an aircraft. The reason for the plane to have a supercomputer on board, is not only to process thousands of different targets in the air, sea, and on the ground; but also to deliver some of the more advanced radar and IR jamming technologies. The radar is also key to the Yang's integrated avionics and sensor capabilities. It will provide pilots with detailed information about multiple threats before the adversary's radar ever detects the Yang (See more in radar section).
Coupled with advanced all-weather ground detection, imaging, and camera technologies; the Yang can detect and target hundreds of airbound threats far before any of the threats can (if it could in the first place) detect the Yang. Also linked to the supercomputer Common Integrated Processor (CIP), is the Electronic Warfare system; in which it detects and locates signals from other aircraft and controls the Yang's expendable countermeasures. he EW aperture locations provide all-aspect coverage, and the system includes a missile launch detection capability.
The Yang uses the AN/APG-77 radar, which in the Yang works with the weapons management system and the electronic warfare system as one, giving the pilot unprecedented situation awareness.
The AN/APG-77 radar is designed for air-superiority and strike operations and features a low observable, active aperture, electronically-scanned array with multi-target, all-weather capability. Also featured in the radar is Highly-Advanced Synthetic Aperture Radar (SAR), in which the radar can detect inbounds some 300 nautical miles away.
Payload
The Yang can carry some 100,000 pounds of ordinances. It can carry a number of different weapons, including free-fall bombs, guided-munitions, nuclear bombs, and a number of different missiles. The bay itself is hidden and would open up upon command by the pilot. The bay is capable of carrying eight cruise or anti-radiation missiles. Also featured on the two sides of the plane are two small places in which doors are power-opened to reveal its subsequent air-to-air missiles. A total of four smaller air-to-air missiles may be carried in these bays.
