NASA Contracts with BWXT Nuclear Energy to Advance Nuclear Thermal Propulsion Technology

NASA

NASA wants to reach Mars with nuclear power

How powerful does a space rocket have to get to Mars? Apparently, rather more than the more modern we have. This is what NASA thinks, which has reopened the door to Advance Nuclear Thermal Propulsion Technology whose possibilities in space exploration seemed forgotten: nuclear fusion.

Nuclear power propulsion is a fairly popular idea in science fiction. NASA has already done some experiments with it in the 1970s, although the risks of using it outweighed the benefits. Instead, he sent Apollo missions to the Moon with conventional fuel, much less powerful and efficient. The tests will take place at the Nevada National Security Site near Las Vegas. Its ultimate goal is to provide enough energy on the surface of the Red Planet for the production of fuel, habitats and other equipment, when humans settle there.

The last time NASA tested a fission reactor was during the 1960s Systems for Nuclear Auxiliary Power (SNAP) program, which developed two types of nuclear power systems. The first system - thermoelectric generators of radioisotopes, or RTGs - takes advantage of the heat released from the natural decomposition of a radioactive element, such as plutonium. RTGs have fueled dozens of space probes over the years, including the explorer Curiosity currently exploring Mars.

The second technology developed under SNAP was an atom division fission reactor. SNAP-10A was the first - and so far, only - US nuclear power plant to operate in space. Launched on April 3, 1965, the SNAP-10A operated for 43 days, producing 500 watts of electrical power, before an unrelated equipment failure ended the show. The spacecraft remains in Earth orbit.

Russia has been much more active developing and flying spacecraft powered by small fission reactors, Radar Ocean Reconnaissance including 30 Satellites, or RORSAT, which flew between 1967 and 1988, and increased power TOPAZ systems. TOPAZ is an acronym for Thermionic Experiment with Conversion in Active Zone.

However, if the agency wants to meet its goal of sending a manned mission to Mars, it must get a whole rabbit out of the hat. It needs an energy source that will shorten the journey to the red planet for several months, thus reducing the exposure of astronauts and spacecraft to space radiation. The options are not too many, so they have ended up turning a blind eye to nuclear power.

To investigate whether it is possible to equip Advance Nuclear Thermal Propulsion Technology by testing such a motor in a manned spacecraft, NASA has awarded a contract worth 18 million to BWXT, a company specializing in generating atomic energy. His challenge is to create an atomic engine powerful enough to go and return to Mars without risking - at least not too much - the life of astronauts.

On the previous occasion they encountered a seemingly insurmountable problem: for an engine of this type to work, it should be heated to more than 2,000 degrees centigrade, a fairly high temperature that can cause an explosion.

The dilemma is there: if we want to explore the Solar System we need a better source of energy for our rockets. Otherwise, they will never be able to go beyond Mars with the greatest possible risks.

Rolls-Royce Reveals Plans for Autonomous Naval Vessel

Rolls-Royce unveils plans for autonomous naval vessel

The ship concept is designed to be capable of operating offshore for more than 100 days, will shift 700 tons and will reach speeds above 25 knots.

Rolls-Royce has unveiled plans for a single-role, autonomous navy vessel concept with a range of 3,500 nautical miles.

The ship concept is designed to be capable of operating offshore for more than 100 days, will shift 700 tons and will reach speeds above 25 knots. The 60-meter-long vessel is designed to perform a series of unique role missions, eg patrol and surveillance, mine detection or fleet screening. The heart of the boat is a robust and reliable propulsion system. This combines proven Rolls-Royce experience in gas and diesel turbines with a proven track record in electric propulsion, power storage and propellers.

According to Benjamin Thorp, Managing Director of Naval Electrics, Automation, and Control at Rolls-Royce, "Rolls-Royce is seeing the interest of the major armies in autonomous ships, rather than remote-controlled ones, reduce crew risk and reduce construction and operating costs.

"Over the next 10 years, Rolls-Royce expects to see the introduction of medium-sized unmanned rigs, particularly in the main armies, as the concept of mixed manned and unmanned fleets develops.".

The largest manned ships will cover multi-role missions. By allowing the composition of the fleet to blend in this way, the marinas will reap the operational and cost benefits of autonomous navy vessel concept.

The initial design features a complete electric propulsion system that requires fewer auxiliary systems (lubrication, cooling system, etc.) and offers better reliability levels than mechanical counterparts. It has two groups of Rolls-Royce MTU 4000 series that provide about 4MW of electrical power to a 1.5MW propulsion unit. An alternative to diesel engines could be small gas turbines, further improving system reliability and reducing on-board maintenance. Azipull permanent magnet propellers, along with a tunnel pusher mounted at the bow, will make the vessel highly maneuverable. To reduce fuel consumption and extend the range of operation, an additional 3000 kWh of energy storage will facilitate efficient low-speed operations and the vessel will also be equipped with photovoltaic solar panels to generate power when the vessel is on hold.

The absence of crew increases the need for very reliable power and propulsion systems. Rolls-Royce's approach is to combine advanced intelligent asset management and system redundancy in a cost-effective way that avoids sacrificing the cost savings and volumes achieved by eliminating the crew. A set of autonomous navy vessel concept support tools, developed by Rolls-Royce, such as energy management, equipment health monitoring and predictive and remote maintenance, will ensure the availability of unmanned vessels.

Many of the technologies needed to make autonomous navy vessel concept ships a reality already exist. Rolls-Royce has created what it believes.

Google X and the Science of Radical Creativity

Google X

Google X is empowering invention with bust of radical creativity

 

Google parent company Alphabet has a very special wing which is working on developing highly influential and quite unbelievable technology, product or service for all. This special wing is called Google X wing which brings together highly powerful minds in varied fields that have a common shared goal of developing solutions to the crucial problems plaguing modern society. In simple words this wing is a kind of Moonshot Factory whose solutions are nothing less than the science fiction.
 

What makes Google X so different from others?

 
Google X will comes as simply one such company where members are encourages to perform regular investigation in the absurd ideas which are permitted anywhere in the world. In this case ‘absurd ideas’ are limited to the science fiction and their task is to investigate whether it is possible to implement in modern day and how feasible will it be. Over the this wing has quietly investigation space elevators and cold fusion which are remarkable absurd ideas in reality but so much in the field of science fiction.

This Moonshot factory has tried and even abandoned wide range of projects over the years which ranges from the developing hoverboards with magnetic levitation technology to extremely cheap fuel from the sea weed. It has met with varied degree of success in different projects and one of its most notable and widely reported projects is self-driving cars. Apart from it it had made drones which can deliver aerodynamic packages and even designed such contact lenses which can measure glucose level from the diabetic person’s tears.
 

Google X is the need of the hour

 
The ideas followed or made into by Google X might appear to be farfetched or too random to show any worth to usual reader. But the engineers and brightest minds at this Moonshot factory adhere to a very simple and potent three part formula. At the very beginning they address a huge problem, secondly they do it by offering a radical solution and thirdly this is achieved by employing a feasible technology.
It is worth noting that Google has created the Google X wing to solve its own problems as there is already massive workforce to deal with it. Rather the Google X division is literary made with the aim of creating such companied which helps in changing the world we live in and become the next age- Google. This wing considers more than 100 such absurd ideas every year which encompasses varied areas like artificial intelligence, clean energy and much more.
 
Innovation powered by secrecy
 
The Google X wing innovation is powered by the highest level of secrecy. Google doesn’t ever share the allotted budget or the number of employees working in the Google X wing even to the investors. Journalists simply has no clue what’s happening behind the closed doors of the Google X wings but it is worth noting that this Moonshot Factory is led by the finest mind in their respective field who knows what they doing or dealing with.

Open Rotor Jet Engine That Could Revolutionize Air Travel

Open Rotor

A new design of with an open rotor jet engine is expected to revolutionize air travel

 
Aerospace will see a new egg shaped jet engine which has the potential to dramatically cut down the fuel consumption and simply change the scenario of modern air travel. This new technology or more importantly the new ‘open rotor’ prototype has been designed by a French engine maker going by the Safran and he is hoping to see them in action by the year 2030. This new technology based engine was developed in association with European Union and it is being tested currently at a French military based present near Marsellie. The Open Rotor engine technology simply bring out the usually hidden whirring part outside in order to capture more air and provide more powerful thrust to the plane.
 

How it works?

 
This new technology based engine design is expected to help in cutting down fuel consumption which will in turn help in reducing the air fares. This engine is designed like an elongated egg having two rows of blades present at the back end. This engine is designed with an aim of burning 15 percent lesser amount of fuel than the current generation of turbofan engines. Even the traditional technology used in the turbofan had improved significantly in the recent past but the prospects & potential of the new egg shaped engine is massive.

This newly engine will be placed right at the back of the airplane rather than being placed right under the wings which has been common place with today’s technology. It will also leave some room for the two rows carbon blades shaped like scimitar which will swirl in the opposite direction.
 

Tinkering with the traditional engine technology & design

 
This isn’t the first that people had decided to tinker with the traditional engine technology and design of our airplanes. In the 1980 a number of US engine makers worked on the unducted fans but this design and technology was dropped as the oil prices steeply declined. During that time airplane engines were considered to be extremely noisy. The current study and change in the popular engine design and technology is powered by the continuous rise in the energy costs and the impositions of different resolution for fewer emissions.

One of the researchers has stated that if we are looking forward to turn this engine into reality by 2030 then the development has begin from today. In case the oil prices ever jumped over $100 then the whole industry will get more interested in such a viable engine technology which reduces the amount of fuel consumption.

It shouldn’t come as a surprise that Rolls Royce has shown its interest in this new peculiar engine technology. A another question which is being thrown at the developers is how the passengers are going to react to find two find two naked engine right at the back of the airplane. Developers have no answer for it and this technology still has to be certified by the regulator before it debuts on the modern planes.
