B2 Spirit Bomber Plane | How Stealth Works?
This is the B-2 Spirit, designed as the tip of the spear in strategic bombing operations. It is a deep penetration bomber intended to pave the way for the B-1 Lancer and ultimately for the massive Cold War era bomber, the Boeing B-52 Stratofortress
Stealth by Design: Deflecting and Absorbing Radar
The B2 Spirit achieves its Mission thanks to its unique Wing structure which deflects radar while the paint absorbs the remaining radar signals rather than deflecting them back to their Source enhancing its stealth capabilities to break it down further the aircraft is constructed from a combination of materials titanium graphite epoxy fiberglass polyamide graphite polyamide and fiberglass epoxy particularly on the Leading Edge and wing tips however don’t be deceived by its seemingly soft outer skin beneath the surface lies a robust framework of high strength steel ribs that allow the wings to flex and bend as needed during flight
Concealed Engines for a Minimal Heat Signature
To further maintain its stealth profile and reduce its heat signature, the engines are buried deep within the aircraft’s body. They draw air from the front and expel only slightly warm air, which prevents these heat-seeking missiles from locking onto the aircraft due to its minimal thermal signature
The Next Generation: B21 Raider
After three decades, the US has sanctioned the newly developed B21 Raider is significantly smaller when placed side by side with an average human. We can notice the difference in size. The new B21 Raider is expected to utilise Advanced stealth Technologies to further reduce its radar cross-section, increasing its survivability against modern air defence systems
Inside the Cockpit
Moving to the B2 Spirits cockpit is compact with the commander and pilot seated side by side interestingly the aircraft is equipped with ejection seats when in an emergency the protective covers pop open to allow the crew to safely evacuate the1 billion aircraft if necessary inside the cockpit Advanced avionic systems are present these include a fuel control system an attitude display umit the weapon control system and a Terrain following radar together these Technologies enable the pilot and co-pilot to navigate and operate the aircraft even in darkness or regions with blind spots area

Historical Foundations: Jack Northrop’s Flying Wing
We will also look into the split Rudder system along with the secret stealth pain material composition all in the video ahead a little history about the B2 Spirit dates back to the designs of revolutionary engineer Jack Northrup who invented the Flying Wing aircraft this design was first introduced in the year 1949 as the LI b49 unfortunately it was rejected at the time but North’s flyby wire technology laid the foundation for advances in stability systems these systems allow inherently unstable aircraft like the D2 Spirit to be flown the conventional aircraft
Internal Structure and Massive Fuel Capacity
Let’s take a look inside the D2 Spirit frame structure at the front is the composite wing tip this section comprises the ribs of the outer part of the wing both integral fuel tanks can hold approximately 167,000 lb which translates to about 75,000 kg of fuel which is a significant amount just a small comparison this aircraft’s fuel Reserve can fill up two tanker trucks making it an in Sly gas guzzling machine moving further back there is another section of the fuel tank these fuel tanks were specifically designed to penetrate deep into Russian territory about 6,900 Mi which is around 11,000 km furthermore it can travel double that distance deep into Enemy Lines while avoiding radar detection thanks to this rotary air refueling system that extends all the way out as shown here this maximizes its range to 12,000 Mi with the Boeing KC 135 Strat tanker and allows it to remain Airborne for 44 hours that is almost 2 Days in the air which is a remarkable engineering feat
Engine Technology and Heat Reduction
All that fuel are consumed by these four General Electric f118 turbofan engines each with 17,300 lb of thrust let’s take a look from the side profile as you can see it has its engine buried deep in the airframe with an S curve in front and behind this is how it reduce it Heat Signature Air is sucked by the fan rotor as it draws in which under goes powerful compression in both the low pressure and high pressure compressors as the air enters the combuster this is where fuel injection occurs this process generates a continuous combustion of fuel and air reaching temperatures of more or less than of 1,000° C the resultant heat causes the gas to expand.
Leading it to escape from the combuster with high energy flowing through both the high and low press turbines as a consequence the turbine blades rotate the energy liberated by this process drives both the compressor and the fan thus producing frust just a reminder the B2 Spirit does not use afterburn because as a stealth bomber it has to compromise on speed to lower its heat signature the exhaust from the engines is mixed with ambient air before it exits the air frame this significantly lowers the temperature of the exhaust hence reducing the Heat Signature suitable for the stealth bomber to remain undetected as much as possible
Unique Flight Control Systems
For a conventional aircraft it has aerons at each wing tip that move opposite one another to roll the plane it also has elevators at the tail that affect pitch and the rudder controls yaw or rotation however if we look at the B2 Spirit it doesn’t have all of those control surfaces like a standard aircraft you’ll notice that there are no leading EDG slats the massive Wing which essentially comprises the entire aircraft generates enough lift on its own instead the B2 Spirit has outboard elevons located here close to the split drag Rudder mid elevons and inboard elevons near the engine exhaust these control surfaces are located all over this area and move independently as a single unit they can move opposite one another to achieve role and work together for pitch control they also use a combination of both for Maneuvers that require some roll and Pitch at the same time
The Split Drag Rudder System
As stated almost every aircraft has a Rudder and elevators to turn and stabilize the plane but the B2 Spirit has none of these this is because any vertical structure would reflect radar waves which is why they had to design it without vertical stabilizer or Rudder at the rear instead they use this technique of split drag Rudders to provide directional stability and control in a flying wi aircraft but there is a catch as opposed to Conventional ruds the control efficiency of split drag Rudders is typically low for small defle ction angles that is why the B2 sprit turns very slowly compared to other military plane each split Rudder consists of two separate panels That Swing Out vertically in opposite directions when the left split Rudder opens it produces drag and causes the B2 Spirit to yaw to the left in the direction of the open split Rudder the same effect occurs with the opposing right side split Rudder this is what happens inside the bit when the pilot pushes the left Rudder pedal the left split Rudder opens causing the aircraft to yaw to the left similarly when the pilot pushes the right Rudder pedal the right split Rudder opens causing the aircraft to yaw to the right
Advanced Material Composition
The B2 Spirit composite can be divided into several parts here we find that all the edges are made of fiberglass epoxy to reflect radar while the largest part of the wing is primarily made of graphite epoxy interestingly the cruise station assembly is made up of aluminum at the base since these areas have to withstand a lot of heat from the engine they are made of titanium a super strong expensive material finally we have fiberglass polyamide a stealthy material able to withstand Heat this is what it looks like with all the labeling and segments assigned to it
Classified Stealth Paint Technology
To give you a better picture, let’s take a look at the 1 billion radar paint technology, which is still classified, but here’s what we know from Aviation experts: it involves the use of radar-absorbing material, also called RAM, which is a polymer-based material applied to the surface of stealth military aircraft like the F-22 Raptor and F-35 Lightning 2
Formidable Payload and Bombing Capability
Moving to the belly of the Beast and opening the Bom Bay door is this weapon adapter suspension which makes this bomber formidable while the B2 Spirit might look small it can fit around 80 numbers and Mark 82 bombs weighing 500 lb yes all these 80 weapons can fit inside this weapon adapter totaling around 40,000 lb which is approximately 18,000 kg of freef fall gravity weapon system depending on the mission the B2 Spirit can switch to this rotary weapon system enabling it to carry around 16 numbers of agm1 158 missiles which can cost around $1.5 million each
Precision Bombing Procedure
When ready a B2 Spirit can drop this weapon payload discreetly the AGM missiles unfold their wings to fly towards the target traveling up to 230 Mi which is around 370 km let’s take a look at how this works step one the bomb deployment platform as previously mentioned a B2 stealth bomber flies in a very high altitude when the aircraft reaches the designated location and the conditions are optimal it can release this specialized M Moab weapon system the bomb is designed for precision. And the deployment height plays a crucial role in its trajectory and Effectiveness then step two comes the targeting Precision the bomb is outfitted with Advanced guidance technology including GPS and inertial navigation systems.
Which are military-grade satellites then comes step three that is adjusting the trajectory the guidance information and data is then transmitted to the bomb’s four lattice Motors fins located at the rear these fins can move and adjust in real time allowing the bomb to correct its core Force as it descends under the force of gravity these adjustments are essential because the weapon does not have thrusters to change its trajectory instead it relies on the movement of these fins and a high altitude drop to control its flight path this is why the bomb must be deployed from a very high altitude so it has enough time and distance to adjust its trajectory accurately here comes the most difficult part.
That is step four impact and penetration the bomb known as the massive ordinance penetrator weighs approximately 30,000 lb which is around 14,000 kg when it reaches its Target it strikes with immense Force designed to penetrate deep into hardened structures such as bunkers the energy upon impact allows the bomb to bury itself over 200 ft into reinforced concrete ensuring it delivers its payload precisely where it is intended for maximum effect
Strategic Bomber Triad: B2, B1, and B52
But why do we need the B2 bomber when we have the B52 out of Fortress animated in our recent video and the B1 Lancer let’s take a look at how this works the first line attack involves the B2 stealth bomber moving in to destroy high value air defense systems like the famous S400 Triumph and other surfac to- a missiles effectively disabling them by using its stealth technology next the B1 Lancer flies at a very low altitude towards enemy targets to take out older anti-aircraft guns and missiles this clears the way for conventional aircraft like the B52 strata Fortress. Which can then sweep into to destroy any critical infrastructure without facing anti-aircraft threats this is the reason they need both the B2 stealth bomber and conventional bombers as there are only 19 units of the B2 spirit in service to date we also make original engineering content so please subscribe and hit the notification Bell for more videos.
