What is Realbigbird?
RBB is a jumbo catamaran biplane so large it could even splash down safely on the open ocean. Framed up with plastic resin laminated oak, its lighter than a metal version, impervious to corrosion, with an infinite modulus of elasticity; turbulence may flex the wings, but it'll never cause stress fractures.
Biplanes have greater maneuverability at lower speed with a shorter wingspan to use narrow meandering rivers. allowing it to maneuver following a fire without ever having stress fractures, and treated to be fire proof. RBB will operate in remote areas. If there is damage from collision or structural problems arise, the materials and craftsmanship for repair is common with wood, not metal.
It is diesel powered, which is less of a fire hazard, and for a given long range, the weight of the engine with its fuel is less than that of AV gas. We see planes burn after a crash because the light alloys are combustable. Because the wood airframe is so light, the stall speed is so slow it can crash land without injury, esp if passengers have airbags.
With slats and Active Aeroelastic wings, stall speed is reduced to 50km/hr (35mph) for air foils that are still efficient at 320 km/hr (200mph), or 100km/hr (60mph) splash down while cruising at 400 km/hr (250). If sheltered water is available, STOL can be sacrificed along with fuel economy allowing top cruising at 600-650 km/hr. However, into a headwind, take off is under 100 meters. This is never gonna run out of runway. Elastic airfoils, which produce this flexibility, also bend metal wings- risking stress fractures; which is not a problem with wood.
The slat, redirecting the air hitting the nose of the air foil, creates a zone of low pressure beneath it, say 10% of the Camber. But when a wing is so big the camber is 8 meters, that zone is 80cm wide, allowing a balcony, like on a ship's bridge, offering passengers an unobstructed view ahead, rather like riding a motorcycle. Or the bow of a flying Titanic.
The tree trunk thick masts of a clipper ship are its drive shafts. RBB has the engines in the bilge of each hull and uses similar timbers to drive the props, which are mounted high as seen on other sea planes. Only, having the weight of the engines so low vastly improves stability.
RBB has no electric, much less computer control. It is impervious to gamma ray burst, lightening, or any other EMP source. The Diesel engines dont even use electronic ignition, impervious to hacking or cyber attack.
Since the cabin is not pressurized, the air is not circulated with the microbes picked up, but constantly refreshed with air intakes. For those who suffer breathing distress, each berth is equipped with an oxygen mask. The cabin air is not enriched with oxygen to compensate for altitude, so the fire hazard on board is minimal.
What is the RBB for?
designed to carry enuf water to be effective fighting record size wildfires. It is also a global Emergency Services vehicle that can splash down in a disaster zone harbor rather than waiting for an airport to be cleaned up. The same tanks used to fight fires can provide potable drinking water, the same berths for smoke jumpers do for medical personnel, or for entrepreneurs looking for opportunity in remote communities. When the ice melts and the NorthWest passage opens, the trick will be in getting goods & services to Churchill to/from East Asia.
Airport security problems resulted in the recent United Airlines passenger problem trying to replace them with security personnel. But with RBB, you get a berth, not a seat, and keep all your luggage with you. But even a bomb does go off, it wont bring RBB down. Like wood framed aircraft 100 years ago, a bomb would merely blow out the fabric cover leaving the timbers intact. Flying at low altitude the cabin is not pressurized, which means the timber frame is not stressed.
Simple design allows the crew to handle refueling and all other services in port, eliminating the risk of saboteurs on airport staffing. Propellers mounted in the upper wing is safer, but powering them with steam turbines rather than aircraft engines saves weight, improving stability, and also increases reliability. While sacrificing some fuel economy, both propellers and airfoils can be adjusted before takeoff- admittedly also longer- to increase cruising speed to 550kmh, meaning from the Hudson to the Thames is a ten hour over nght flight in a comfy berth.The same high pressure pumps that power the jet skis to & from the dock and then take off, power the water canon to fight fire. It is "STOL", ie Short Take Off & Landing, to utilize rivers, lakes, & reservoirs, which also allows it to fly slow to better aim water canons at hot spots. Biplanes have shorter wingspans so it can use narrow meandering rivers & oxbow ponds. The catamaran has shallow draft so it can adapt to low water conditions such as droughts commonly cause.
During the wet season, or when not needed for emergency disaster services, Realbigbird can profitably deliver freight & passengers to remote communities that have lakes, rivers, reserviors, or harbors. Altho it cruises slower, 300mph, it is roomy enuf inside that passengers get a cabin, not just a seat, and can sleep all night to arrive in the morning. They can stow their own luggage in the cabin with them never loosing it.
