AAWSAP DIRD, Antigravity for Aerospace Applications, March 2010

This Defense Intelligence Reference Document, dated 30 March 2010, was prepared by the Defense Intelligence Agency's Defense Warning Office under the Advanced Aerospace Weapon System Applications Program. It reviews theoretical approaches to antigravity for aerospace propulsion. These range from Newtonian mass arrangements and general relativistic gravitomagnetic effects to negative energy, dark energy and quantum vacuum forces. The report concludes that many of these concepts are nowhere near practical engineering implementation. It offers theoretical estimates to guide future work.

This document is a Defense Intelligence Reference Document (DIRD), a technical reference format used by the Defense Intelligence Agency (DIA) to capture baseline knowledge on a specific topic for later analytic use. DIRDs are best understood as reference and synthesis products rather than as original research. It is one of 38 DIRDs produced under the Advanced Aerospace Weapon System Applications Program (AAWSAP) between 2009 and 2011. Because AAWSAP’s scope permitted a broad range of supporting topics, not every DIRD in the series directly concerns aerospace systems or future threat assessment. The following summary reflects the DIRD’s scope and framing at the time of writing and should not be read as implying current validation of the concepts discussed. This DIRD surveys a range of proposed “antigravity,” or gravitational control, concepts for aerospace applications, drawing mainly from Newtonian gravity, general relativity, cosmology, and quantum field theory to hypothesize that gravity might someday be reduced, counteracted, or redirected as a means of propulsion. The report reviews mechanisms including ultra-dense matter, gravitomagnetic effects, relativistic moving masses, negative energy, dark or vacuum energy, and quantum vacuum or dispersion-force approaches, while presenting some of these ideas as theoretically permissible under extreme, idealized conditions within established physics. However, it notes that any practical implementation faces currently insurmountable engineering barriers, including astronomical energy requirements, currently unproven exotic matter conditions, kilometer-scale or otherwise unbuildable apparatuses, and highly immature experimental foundations. Although the report draws on broadly accepted theoretical concepts, its implication that those concepts might eventually yield viable “antigravity” propulsion systems deviates significantly from mainstream physics consensus.

According to Maxwellian electrodynamics, an electric current flowing through a wire that
is wrapped around a torus (or ring) causes a magnetic field to form inside the torus. If
the current (I) in the wire increases with time, then the magnetic field B inside the
torus also increases with time. This time-varying magnetic field in turn creates a dipole
electric field E, as shown in Figure 1. The magnitude of the electric field at the center of
the torus is given by:

where μo is the vacuum electromagnetic permeability constant (4n x 10-7 H/m), N is the
total number of turns of wire wound around the torus, i is the time rate-of-change of
the electric current flowing through the wire, r is the radius of one of the loops of wire,
and Rt is the radius of the torus.

In a similar fashion, Forward's antigravity device is a dipole gravitational field
generator. As shown in Figure 2, a mass flow T through a pipe wound around a torus
induces a Lense-Thirring field P to form inside the torus. If the mass flow is
accelerated, then the P-field increases with time, and thus a dipole gravitational field G
is created. The magnitude of the anti-gravitational field at the center of the torus is
given by:
