Неподвижные электрические заряды размещаются в пространстве или дискретно - в отдельных точках, или непрерывно - вдоль какой-то линии, на поверхности какого-либо тела, или, наконец, в каком объеме.
Для случая непрерывного распределения электрических зарядов вводится понятие плотности зарядов. При непрерывном распределении зарядов вдоль линии вводят линейную плотность электрических зарядов.

Как Вы думаете заряды какой группы в шаре являются скомпенсированными, а какие нет?

jnet смотрите. легкие аэроионы кислорда воздуха живут в естественной среде 40-60 секунд. Ок допустим прогоняя ионизированный воздух через сильное магнитное поле мы успеем разделить эти аэроионы до того как они сформируют нейтральную молекулу.  То есть произойдет дисоциация ионизированного воздуха. А сколько они проживут в этом самом резиновом шаре? Какова продолжительность жизни такого изолированного рт внешней среды аэроиона? На чем зиждеться Ваша уверенность, что отрицательные аэроионы в шаре будут стабильны длительное время?

PRESS RELEASE  UPDATED: MAR 13, 2017 17:06 CET

This milestone opens the door for safer and more efficient Space access for small satellites

Barcelona, Spain, March 13, 2017   (Newswire.com) - Zero 2 Infinity, a company specialized in Space transportation systems, successfully launched its first rocket from the Edge of Space on March 1st.

Part of the Zero 2 Infinity team sailed a few miles off the Spanish coast to launch the balloon carrying the rocket. After soaring to 25 km (more than twice the cruising altitude of commercial airplanes), the other part of the launch team gave the order of the controlled ignition of the first Bloostarprototype from the facilities of the National Institute of Aerospace Technology (INTA) in El Arenosillo (Huelva, Spain).

The goals of the mission were: (i) validation of the telemetry systems in Space conditions, (ii) controlled ignition, (iii) stabilization of the rocket, (iv) monitoring of the launch sequence, (v) parachute deployment, and finally, (vi) sea recovery. All these goals were achieved in full.

This mission is part of the development of Bloostar, the first small satellite launcher to use a stratospheric balloon as a first stage. By initiating the rocket ignition from above  airspace, the targeted orbit can be reached with expediency and efficiency.

This patented technique is less risky than any systems used until now. The rocket-powered phase starts already from above 95% of the mass of the atmosphere, getting there with no polluting emissions. Besides the environmental angle, this new method lets Zero 2 Infinity launch satellites with more flexibility (2 weeks notice), at a drastically lower cost and more often than ever before.

Господа, а нет ли желающих (спецов по микроконтроллерам, программированию оных) реально поработать на идею этого аэростатного запуска? Писать лучше по делу на указаный в профиле мейл.
В Москве.

А что конкретно? 

Всё остальное кроме чипа уже готово? 

Или есть место для творчества?

Using Balloons to Launch Rockets
Since the turn of the century, space exploration has changed  dramatically thanks to the unprecedented rise of commercial aerospace  (aka. NewSpace). With the goal of leveraging new technologies and  lowering the costs of launching payloads into space, some truly  innovative and novel ideas are being put forth. This includes the idea  of using balloons to carry rockets to very high-altitudes, then firing  the payloads to their desired orbits.


Also known as "Rockoons", this concept has informed Leo Aerospace's  fully-autonomous and fully-reusable launch system – which consists of a  high-altitude aerostat (balloon) and a rocket launch platform. With the  first commercial launches slated for next year, the company plans to  use this system to provide regular launch services to the microsatellite  (aka. CubeSat) market in the coming years.


The concept of the Rockoon is one of many air-launch-systems that have been investigated and validated since the Space Age  began. Unlike conventional rockets, which rely on massive amounts of  propellant to achieve escape velocity and send payloads to orbit,  air-launch-systems rely on the comparatively cost-effective method of  transporting a payload to high altitude where it can then be sent to Low  Earth Orbit (LEO).

All of this allows for much smaller  and lighter launch vehicles to be used, which leads to significantly  reduced costs. This method is especially effective when it comes to  small payloads like microsatellites, which are becoming all the more  common.


Today, most air-launch-systems that are being pursued involve  aircraft bringing rockets or spacecraft with rocket motors to launch  altitudes – such as Virgin Galactic's SpaceShipTwo, Virgin Orbit's LauncherOne, or the Stratolaunch  air carrier. However, the Los Angeles-based Leo Aerospace company chose  to investigate the equally valid method of relying on a  lighter-than-air (LTA) platform to get payloads to space.


As Dane Rudy, co-founder and CEO of Leo Aerospace, told Universe Today via email:

 
 "Fr om a first-order physics  perspective, balloon launch is a very elegant solution to providing an  efficient and cost-effective launch for small payloads. Additionally,  this architecture dramatically reduces the amount of launch  infrastructure required, enabling a fully mobile solution."


The central components of this launch system are the Regulus Orbital launch platform and the Orbital Rocket.  The Regulus platform provides autonomous flight control through a  series of burners (which ensure that the aerostat remains buoyant) and a  rotational control system of bipropellant thrusters, all of which are  mounted to an insulated body composed of composite material.

Once the  aerostat reaches a deployment altitude of 18,000 meters (60,000 ft), the  rocket will launch and carry the payload to its desired orbit.  According to the company's mission profiles page, the system will be capable of conducting multiple types of deliveries to different altitudes.


"The development and production cost of a balloon system is orders of  magnitude less than using an airplane," said Rudy. "Compared to other  balloon systems that use lifting gas, our hot-air architecture is fully  and rapidly reusable. We can conduct dozens of launches with a single  system before refurbishments are required."

 
 These will range from suborbital missions – wh ere payloads are sent  to altitudes over 100 km (62 mi) – to orbital missions, wh ere CubeSats  will be sent to sun-synchronous orbit (SSO) of 550 km (340 mi). Another  possibility they are sure to mention involves the delivery of  humanitarian aid or emergency communications equipment to remote regions  that are inaccessible to fixed-wing aircraft, drones, or other aerial  vehicles.


The company also plans to incorporate gliders and drones that can  deploy from their aerostats, thus offering other mission profiles – such  as drone monitoring, scientific experiments, and communications  services. In addition to being a more cost-effective means of placing  small payloads in orbit, the launch system also has the benefit of being  very compact.

Credit: Leo AerospaceBecause  of this, the rocket, aerostat, and machinery needed for inflating it  can all be placed into a standard shipping container, loaded onto a  semi-truck, and then shipped wherever it is needed. The trailer cab also  serves as the initial communications station for the launch. This level  of mobility and flexibility is one of the characteristics that could  make aerostat platforms effective at delivering emergency aid and relief  services. As Rudy said:

 
 "We are beginning to uncover  many different use cases for the reusable and autonomous aerostat  platform that we are developing. It is entirely mobile and fits into a  standard shipping container, making it easy to transport and store.  Additionally, it is simple to operate and incredibly robust. Unlike  lifting gas balloons, our system can still operate with a hole the size  of a car in the balloon material. Our collaborators are excited to  leverage these capabilities to rapidly deploy sensor suites in disaster  areas post-hurricane or provide emergency relief supplies in places that  are difficult to reach. It has been incredible to work with groups like  the Army Space and High-Altitude Experiments branch to identify and  solve such a range of problem cases."


All of this puts companies like Leo Aerospace, and others that are  pursuing lighter-than-air concepts, in good stead to take advantage of  the growth in the satellite market. Between the proliferation of  microsatellites (aka. CubeSats) and the emergence of light-payload  launch services (like Rocketlab and Virgin Orbit), this market is  expected to explode in the coming years.


What sets Leo Aerospace apart, however, is the way they are focused  on the delivery of satellites that weigh less than 25 kg (55lbs). As  Rudy explained, there isn't a dedicated solution yet for microsatellites  that fall into this range. Typically, CubeSats are forced to  "rideshare" on launch rockets, wh ere they take up free space alongside  heavier payloads.

  "This is extra surprising  given that almost half of all satellites in the next 10 years are  projected to fall within this segment. We have worked hard to capture  and maintain a first mover advantage in the 25kg segment. We have  conducted the most extensive operations and testing of our vehicle.  Additionally, we are the furthest in regulatory work through our close  relationship with the FAA and active membership in the Commercial  Spaceflight Federation. Finally, our system is tailored to provide the  dedicated launch that our customers need, and at a high enough frequency  to address the incredible demand."


By the end of 2018, the company had successfully completed a launch-test campaign and secured funding through the National Science Foundation  and a venture capital firm. In 2020, they hope to fully flight-qualify  their platform by conducting their first flight, which will be followed  by commercial operations and maybe even contracts with NASA.


"These commercial operations will be our entry into the $2.6B High-Altitude Platform Services  market with a range of civil, defense, and commercial customers," said  Rudy. "We have been working with NASA JPL to explore several different  use cases. One example is carrying Martian entry vehicles into the upper  atmosphere here on Earth and dropping them to collect data and test  aerodynamic performance."


From its humble beginnings, the full-scale commercialization of space  has been progressing by leaps and bounds in recent years. Between  declining launch costs, the development of smaller payloads, and the  rise of commercial launch providers that can accommodate smaller  payloads, Low Earth Orbit (LEO) is likely to become a very busy place in  the near future!
