  "textContent": "A turbomachine dual spool transmission system (700) can include a direct drive assembly (701) configured to selectively allow bypassing of a dual spool differential combination output (107) to allow selective direct engagement of a low pressure spool (LS) to directly drive a rotational member (703; 109) or to be directly driven by the rotational member. The system can include the dual spool differential. The dual spool differential can include a gear assembly configured to combine a low pressure spool input and a high pressure spool input into a combination output to provide an output speed range smaller than a low pressure speed range alone.",
