El costo de la defensa de misiles balísticos láser basados en el espacio
Science (New York, N.Y.)
|March 21, 1986
Resumen
La relación de intercambio de costos para los sistemas de defensa de misiles balísticos con láser infrarrojo en órbita es probablemente mayor que 1. Esto sugiere que el despliegue de misiles más ofensivos puede ser más rentable que desarrollar este sistema de defensa estratégica.
Área de la Ciencia:
- Ingeniería Aeroespacial Ingeniería Aeroespacial.
- Tecnología de Defensa Tecnología de Defensa.
- Estudios Estratégicos Estudios Estratégicos
Sus antecedentes:
- La Iniciativa de Defensa Estratégica propuso plataformas láser infrarrojas en órbita como un sistema de defensa de misiles balísticos.
- Contrarrestar dicho sistema puede implicar aumentar el número de misiles ofensivos.
Objetivo del estudio:
- Examinar los métodos para calcular la relación de intercambio de costos de los sistemas de defensa de misiles balísticos propuestos.
- Evaluar la viabilidad económica de los sistemas de defensa láser infrarrojo en órbita contra misiles balísticos intercontinentales.
Principales métodos:
- Cálculo de la relación costo-intercambio: costo de defensa por misil destruido frente al costo de ataque por misil desplegado.
- Analizando un escenario con una defensa láser infrarrojo en órbita contra lanzamientos simultáneos de misiles balísticos intercontinentales.
- Estimando los límites inferiores para los costos de defensa y los límites superiores para los costos de ataque.
Principales resultados:
- Se encontró que la relación de intercambio de costos para un sistema de defensa de misiles balísticos de láser infrarrojo en órbita era sustancialmente mayor que 1.
- Esto indica que el costo de desplegar contramedidas (misiles ofensivos) es menor que el costo del sistema de defensa.
Conclusiones:
- El sistema de defensa de misiles balísticos analizado puede no cumplir con los requisitos de efectividad si su costo excede el de la proliferación de misiles.
- La metodología para calcular la relación costo-intercambio se puede aplicar a varios sistemas de defensa estratégica propuestos.

01:18Projectile Motion: Example
The theory of projectile motion is very useful for players of several sports to improve their performance. For example, a javelin thrower needs to throw their javelin in such a way that it travels as far as possible. The javelin thrower takes a short run-up to increase the initial speed of the javelin. The range of a projectile is at its maximum at a 45° angle so javelin throwers try to angle their throw as close to 45° as possible.

01:13Rocket Propulsion in Empty Space - I
The driving force for the motion of any vehicle is friction, but in the case of rocket propulsion in space, the friction force is not present. The motion of a rocket changes its velocity (and hence its momentum) by ejecting burned fuel gases, thus causing it to accelerate in the direction opposite to the velocity of the ejected fuel. In this situation, the mass and velocity of the rocket constantly change along with the total mass of ejected gases. Due to conservation of momentum, the rocket's...
01:09Radiation Pressure: Problem Solving
The radiation pressure applied by an electromagnetic wave on a perfectly absorbing surface equals the energy density of the wave. The wave's momentum also gets transferred to the surface when an electromagnetic wave is entirely absorbed by it. The rate at which momentum is transmitted to an absorbing surface perpendicular to the propagation direction equals the force on the surface.
The average value of the rate of momentum transfer divided by the absorbing area represents the average force per...

01:02Flame Photometry: Overview
Flame photometry, also known as flame emission spectrometry, is a technique used for the qualitative and quantitative analysis of elements present in a sample using a flame as the source of excitation energy. The concept of flame photometry was realized in the early 1860s by Kirchhoff and Bunsen, who discovered that specific elements emit characteristic radiation when excited in flames. The first instrument developed for this purpose was used to measure sodium (Na) in plant ash using a Bunsen...
01:26Impact: Problem Solving
In an experiment conducted during a Mars mission, a rover propels a projectile with an initial velocity, and the projectile rebounds after colliding with the Martian surface. To ascertain the maximum height attained by the projectile after this collision, the known restitution coefficient and acceleration due to gravity are employed.
By designating the launch point as the origin and utilizing kinematic equations, the vertical component of the projectile's velocity at the point of impact is...

01:29Real-World Applications of Space Curves
Modern aerospace navigation depends on the accurate prediction of motion in three-dimensional space. In defense applications, radar systems continuously track both interceptors and moving aerial targets to find whether their flight paths will result in a collision. These motions are modeled mathematically as space curves, which represent paths that change continuously with time. Each object’s position is described by a vector function that specifies its location in terms of time-dependent...
