Lockheed Tests Unmanned Minehunter Using Innerspace’s 4500 Thruster

An unmanned minehunting vehicle developed by Lockheed Martin showed improved reliability in tests, moving it a step closer to use on U.S. warships. This information came right from a Navy spokesperson. An improved version of the Remote Minehunting System went through 850 hours of testing, clearing the road for 10 weeks of development and operational [...]

Relationships – Self Propelled Underwater Vehicles In Steady Motion

RELATIONSHIPS FOR SELF PROPELLED UNDERWATER VEHICLES IN STEADY MOTION - by Calvin A. Gongwer ABSTRACT A method is given for estimating propulsion performance for underwater vehicles in which the effect of the vehicle wake is taken into account. Computation charts for use of designers are included. The method is generalized so that it is applicable to [...]

Static Testing Dissertation

STATIC TESTING OF UNDERWATER THRUSTERS - by Calvin A. Gongwer ABSTRACT Acceptance testing of thrusters involves static thrust measurements.  Various static thrust measuring systems are shown. Thrust balance types include: parallelogram, bell crank, vertical beam, direct hanging, direct weighing, floating lateral, rolling lateral, and sliding lateral. The principle of null positioning to insure accuracy [...]
