Computations of the rise maneuver with surfacing compare well with experiments, including a crashback maneuver to stop the submarine. Operation Zigzag Operation Locksmith Operation Broadsword Operation Treasure Operation Sherlock Operation Cameo Operation Rose Operation Watchmaker Operation Overlord Operation Jedburgh Operation Butterfly Operation Liberty. The results show that computational fluid dynamics can predict well motions and speeds for free-sailing conditions, but controller commands are harder to replicate. This study analyzes a 20-degree turning maneuver with vertical control commanding the stern planes and a 20/20 zigzag maneuver with vertical control commanding both sail and stern planes, both of them at a nominal speed of 10 knots, and a 20-degree rise maneuver with horizontal control at 12 knots. Computations were performed with explicitly gridded sailplanes, tail planes, and propellers using a dynamic overset technique. Booktopia has Spy Runner, Ronnie Reed and Agent Zigzag, Operation Mincemeat and the Cambridge Spies by Nicholas Reed. The 14-month grand-jury investigation, known as 'Operation Zig Zag,' led to the arrests of 11 of 16 people. The free-sailing experiments, performed at Maritime Research Institute Netherlands (MARIN), are unique in that they present an open dataset for the community to benchmark maneuvering prediction methodologies. Pennsylvania Attorney General Tom Corbett and Delaware County authorities announced yesterday that they have shut down a 1.5-million drug ring, dealing a blow to Southeastern Pennsylvania's methamphetamine trade. We present simulations and experiments of the generic submarine Joubert BB2 performing standard turn, zigzag, and surfacing maneuvers in calm water at depth.
