Abstract

Abstract An airborne air-to-ground ''''wide angle'''' sighting device which avoids optical aberrations inherent in aligning sights and target with vision through transparencies which are not optically inert or caused by faulty alignment of eye and sight. Narrow beam light, preferably monochromatic, e.g. a laser, is projected from aircraft onto ground and pilot viewing illuminated spot through viewer which enhances spot against varied background uses spot as sight. Device includes means for orienting fixed or moving beam in predetermined relationship to aircraft or armament to allow for various parameters such as altitude, speed, trajectories, etc.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 110 words
In an aircraft control system, the combination of: a. a source of a narrow beam of light mounted on the aircraft; b. means for projecting said beam of light out of said aircraft along a predetermined direction with respect to said aircraft; and c. viewing means fixed with respect to and moveable with the pilot''s line of vision for enabling said pilot to distinguish the point of impact of said beam on terrain flown over by said aircraft while moving his line of vision without causing optical aberrations affecting orientation of said point of impact with respect to said terrain whereby said point of impact will constitute an aiming point.
Claim 2
Dependent Claim 110 words
In an aircraft control system, the combination of: a. a source of a narrow beam of light mounted on the aircraft; b. means for projecting said beam of light out of said aircraft along a predetermined direction with respect to said aircraft; and c. viewing means fixed with respect to and moveable with the pilot''s line of vision for enabling said pilot to distinguish the point of impact of said beam on terrain flown over by said aircraft while moving his line of vision without causing optical aberrations affecting orientation of said point of impact with respect to said terrain whereby said point of impact will constitute an aiming point.
Claim 3
Dependent Claim 140 words
Airborne wide angle sighting apparatus for an aircraft control system comprising: a. means attached to an aircraft for generating a narrow, intense beam of substantially monochromatic light; b. reflecting means for directing said beam out of said aircraft in a predetermined direction with respect to said aircraft so that impact of said beam with the terrain over flown illuminates a spot on said terrain with respect to which said aircraft has a predetermined attitude; c. light viewing means moveable with the pilot of said aircraft and interdicting the sight of one eye of said pilot to permit him to maintain unimpaired observation of said spot while performing normal functions; and d. said light viewing means including means for enhancing visibility of said spot against the terrain background whereby said pilot sees said spot as a bright spot on the terrain.
Claim 4
Dependent Claim 140 words
Airborne wide angle sighting apparatus for an aircraft control system comprising: a. means attached to an aircraft for generating a narrow, intense beam of substantially monochromatic light; b. reflecting means for directing said beam out of said aircraft in a predetermined direction with respect to said aircraft so that impact of said beam with the terrain over flown illuminates a spot on said terrain with respect to which said aircraft has a predetermined attitude; c. light viewing means moveable with the pilot of said aircraft and interdicting the sight of one eye of said pilot to permit him to maintain unimpaired observation of said spot while performing normal functions; and d. said light viewing means including means for enhancing visibility of said spot against the terrain background whereby said pilot sees said spot as a bright spot on the terrain.
